+# About Icinga Web 2 <a id="about"></a>
+
+Icinga Web 2 is a powerful PHP framework for web applications that comes in a clean and reduced design.
+It's fast, responsive, accessible and easily extensible with modules.
+
+## Installation <a id="about-installation"></a>
+
+Icinga Web 2 can be installed easily from packages from the official package repositories.
+Setting it up is also easy with the web based setup wizard.
+
+See [here](02-Installation.md#installation) for more information about the installation.
+
+## Configuration <a id="about-configuration"></a>
+
+Icinga Web 2 can be configured via the user interface and .ini files.
+
+See [here](03-Configuration.md#configuration) for more information about the configuration.
+
+## Authentication <a id="about-authentication"></a>
+
+With Icinga Web 2 you can authenticate against relational databases, LDAP and more.
+These authentication methods can be easily configured (via the corresponding .ini file).
+
+See [here](05-Authentication.md#authentication) for more information about
+the different authentication methods available and how to configure them.
+
+## Authorization <a id="about-authorization"></a>
+
+In Icinga Web 2 there are permissions and restrictions to allow and deny (respectively)
+roles to view or to do certain things.
+These roles can be assigned to users and groups.
+
+See [here](06-Security.md#security) for more information about authorization
+and how to configure roles.
+
+## User preferences <a id="about-preferences"></a>
+
+Besides the global configuration each user has individual configuration options
+like the interface's language or the current timezone.
+They can be stored either in a database or in .ini files.
+
+See [here](07-Preferences.md#preferences) for more information about a user's preferences
+and how to configure their storage type.
+
+## Modules
+
+Modules extend Icinga Web 2 with additional functionality. They allow the integration of
+capabilities into existing views and even other modules. Be it a graph provider such as
+[Graphite](https://github.com/Icinga/icingaweb2-module-graphite) or a UI for the Icinga 2
+configuration like the [Director](https://github.com/Icinga/icingaweb2-module-director).
+
+See [here](08-Modules.md#modules) for information on how to install and configure modules.
+
+### The monitoring module <a id="about-monitoring"></a>
+
+> **Note for Icinga DB Users**
+>
+> This module is only for the IDO backend. Use [Icinga DB Web](https://github.com/Icinga/icingadb-web) instead.
+
+This is the core module for most Icinga Web 2 users.
+
+It provides an intuitive user interface for monitoring with Icinga 2.
+There are lots of list and detail views (e.g. for hosts and services)
+you can sort and filter depending on what you want to see.
+
+You can also control the monitoring process itself by sending external commands to Icinga.
+Most such actions (like rescheduling a check) can be done with just a single click in the UI.
+
+More details about this module can be found in [this chapter](../modules/monitoring/doc/01-About.md#monitoring-module-about).
+
+### Documentation <a id="about-documentation"></a>
+
+With the documentation module you can read the documentation of the framework (and any module) directly in the user interface.
+
+The module can also export the documentation to PDF.
+
+More details about this module can be found in [this chapter](../modules/doc/doc/01-About.md#doc-module-about).
+
+### Translation <a id="about-translation"></a>
+
+Icinga Web 2 and all modules by Icinga utilize gettext to provide translations into other languages from the default
+English (en_US). However, the actual language specific files (locales) are not separately included in every project.
+
+Icinga uses a central repository to manage locales: https://github.com/Icinga/L10n
+
+If you want to provide or update a translation for your own language, please head over there where you will find
+[instructions](https://github.com/Icinga/L10n/blob/main/CONTRIBUTING.md) on how to contribute.
+
+## Accessibility <a id="about-accessibility"></a>
+
+In the Icinga Web 2 interface even the blind can see -
+easy navigation with a screen reader and specific themes for different kinds of vision deficiencies
+make it possible for everyone to monitor their systems without impairments.

+# Installation <a id="installation"></a>
+
+The preferred way of installing Icinga Web 2 is to use the official package repositories depending on which operating
+system and distribution you are running.
+
+Please follow the steps listed for your operating system. Packages for distributions other than the ones
+listed here may also be available. Please refer to [icinga.com/get-started/download](https://icinga.com/get-started/download/#community)
+for a full list of available community repositories.
+
+## Browser Support
+
+Icinga Web 2 and modules made by Icinga don't require a particular browser or set of browsers. The
+vendor of the browser in question doesn't matter much. However, the features a browser supports do.
+
+This generally applies to CSS and Javascript features. Since there a plethora of features in each
+category which Icinga Web 2 and modules may require, we will only mention the most prominent feature
+or sub-category here:
+
+* For CSS this is [the flexible box layout module](https://caniuse.com/flexbox)
+* For Javascript it is [the ECMAScript 2015 specification](https://caniuse.com/es6)
+
+If your desired browser and its version is showing up in green when visiting the respective link,
+it's probably okay to use it for Icinga Web 2.
+
+## Upgrade <a id="upgrade"></a>
+
+In case you are upgrading from an older version of Icinga Web 2
+please make sure to read the [upgrading](80-Upgrading.md#upgrading) section
+thoroughly.
+<!-- {% elif not from_source %} -->
+
+## Installation Requirements <a id="installation-requirements"></a>
+
+* [Icinga 2](https://icinga.com/docs/icinga-2) and [Icinga DB](https://icinga.com/docs/icinga-db) to
+ monitor your infrastructure
+* A web server, e.g. Apache or Nginx
+* PHP version ≥ 7.2
+
+### Optional Requirements
+
+* The [pdfexport](https://github.com/Icinga/icingaweb2-module-pdfexport) module (≥0.10) is required for the
+ export to PDF
+* LDAP PHP library when using Active Directory or LDAP for authentication
+
+## Add Icinga Package Repository <a id="add-icinga-package-repository"></a>
+
+You need to add the Icinga repository to your package management configuration for installing Icinga Web 2.
+If you've already configured your OS to use the Icinga repository for installing Icinga 2, you may skip this step.
+
+<!-- {% if debian %} -->

+rpm --import https://packages.icinga.com/icinga.key
+wget https://packages.icinga.com/centos/ICINGA-release.repo -O /etc/yum.repos.d/ICINGA-release.repo
+```
+
+The packages for CentOS depend on other packages which are distributed
+as part of the [EPEL repository](https://fedoraproject.org/wiki/EPEL).
+
+CentOS 7:
+
+```bash
+yum install epel-release
+```
+
+Since Icinga Web v2.5 we also require a **newer PHP version** than what is available
+in RedHat itself. You need to enable the SCL repository, so that the dependencies
+can pull in the newer PHP.
+
+```bash
+yum install centos-release-scl
+```
+<!-- {% endif %} -->
+
+<!-- {% if rhel %} -->
+### RHEL Repository <a id="rhel-repository"></a>

+wget https://packages.icinga.com/subscription/rhel/ICINGA-release.repo -O /etc/yum.repos.d/ICINGA-release.repo
+```
+
+If you are using RHEL you need to additionally enable the `optional` and `codeready-builder`
+repository before installing the [EPEL rpm package](https://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F).
+
+#### RHEL 8
+
+```bash

+
+You need to additionally enable a couple of SLES repositories to fulfill dependencies:
+
+```bash
+source /etc/os-release
+
+SUSEConnect -p sle-module-desktop-applications/$VERSION_ID/x86_64
+SUSEConnect -p sle-module-development-tools/$VERSION_ID/x86_64

+SUSEConnect -p PackageHub/$VERSION_ID/x86_64
+```
+<!-- {% endif %} -->
+
+<!-- {% if amazon_linux %} -->
+### Amazon Linux 2 Repository <a id="amazon-linux-2-repository"></a>
+

+
+ A paid repository subscription is required for Amazon Linux repositories. Get more information on
+ [icinga.com/subscription](https://icinga.com/subscription)

+ Don't forget to fill in the username and password section with your credentials in the local .repo file.
+
+```bash
+rpm --import https://packages.icinga.com/icinga.key
+wget https://packages.icinga.com/subscription/amazon/ICINGA-release.repo -O /etc/yum.repos.d/ICINGA-release.repo
+```
+
+You need to install and enable the `amazon-linux-extras` repository to meet the requirements of
+Icinga Web 2 on Amazon Linux 2:
+
+```bash
+yum install -y amazon-linux-extras
+
+amazon-linux-extras enable php8.0
+```
+<!-- {% endif %} -->
+
+## Install Icinga Web 2 <a id="install-icingaweb2"></a>
+
+You can install Icinga Web 2 by using your distribution's package manager to install the `icingaweb2` package.
+The additional package `icingacli` is necessary to follow further steps in this guide.
+
+<!-- {% if debian %} -->
+<!-- {% if not icingaDocs %} -->
+#### Debian
+<!-- {% endif %} -->
+```bash
+apt-get install icingaweb2 icingacli
+```
+<!-- {% endif %} -->
+
+<!-- {% if ubuntu %} -->
+<!-- {% if not icingaDocs %} -->
+#### Ubuntu
+<!-- {% endif %} -->
+```bash
+apt-get install icingaweb2 libapache2-mod-php icingacli
+```
+
+The additional package `libapache2-mod-php` is necessary on Ubuntu to automatically
+install a web server and PHP and make Icinga Web 2 work out-of-the-box.
+<!-- {% endif %} -->
+
+<!-- {% if centos or rhel or amazon_linux %} -->
+!!! tip
+
+ If you have [SELinux](90-SELinux.md) enabled, the package `icingaweb2-selinux` is also required.
+<!-- {% endif %} -->
+
+<!-- {% if centos %} -->
+<!-- {% if not icingaDocs %} -->
+#### CentOS
+<!-- {% endif %} -->
+```
+yum install icingaweb2 icingacli
+```
+<!-- {% endif %} -->
+
+<!-- {% if rhel %} -->
+<!-- {% if not icingaDocs %} -->
+#### RHEL
+<!-- {% endif %} -->
+#### RHEL 8
+```bash
+dnf install icingaweb2 icingacli
+```
+
+#### RHEL 7
+```bash
+yum install icingaweb2 icingacli
+```
+<!-- {% endif %} -->
+
+<!-- {% if sles %} -->
+<!-- {% if not icingaDocs %} -->
+#### SLES
+<!-- {% endif %} -->
+```bash
+zypper install icingaweb2 icingacli
+```
+<!-- {% endif %} -->
+
+<!-- {% if amazon_linux %} -->
+<!-- {% if not icingaDocs %} -->
+#### Amazon Linux 2
+<!-- {% endif %} -->
+```bash
+yum install icingaweb2 icingacli
+```
+<!-- {% endif %} -->
+
+## Install the Web Server <a id="install-the-web-server"></a>
+
+Ensure that you have a web server with PHP installed before proceeding,
+such as Apache or Nginx with PHP version ≥ 7.2. Depending on your operating system,
+you may need to install and configure the web server separately.
+An Apache configuration file to serve Icinga Web is already installed.
+If you want to use Nginx, you must manually create a configuration file using the following command.
+Save the output as a new file in the web server configuration directory:
+
+```bash
+icingacli setup config webserver nginx --document-root /usr/share/icingaweb2/public
+```
+
+## Prepare Web Setup <a id="prepare-web-setup-from-package"></a>
+
+You can set up Icinga Web 2 quickly and easily with the Icinga Web 2 setup wizard which is available the first time
+you visit Icinga Web 2 in your browser. When using the web setup you are required to authenticate using a token.
+In order to generate a token use the `icingacli`:
+
+```bash
+icingacli setup token create
+```
+
+In case you do not remember the token you can show it using the `icingacli`:
+
+```bash
+icingacli setup token show
+```
+
+<!-- {% if debian or ubuntu %} -->
+You need to manually create a database and a database user prior to starting the web wizard.
+This is due to local security restrictions whereas the web wizard cannot create a database/user through
+a local unix domain socket.
+
+```bash
+MariaDB [mysql]> CREATE DATABASE icingaweb2;
+
+MariaDB [mysql]> GRANT ALL ON icingaweb2.* TO icingaweb2@localhost IDENTIFIED BY 'CHANGEME';
+```
+
+You may also create a separate administrative account with all privileges instead.
+
+!!! note
+
+ This is only required if you are using a local database as authentication type.
+<!-- {% endif %} -->
+
+### Start Web Setup <a id="start-web-setup-from-package"></a>
+
+Finally visit Icinga Web 2 in your browser to access the setup wizard and complete the installation:
+`/icingaweb2/setup`.
+
+<!-- {% if debian or ubuntu %} -->
+!!! hint
+
+ Use the same database, user and password details created above when asked.
+<!-- {% endif %} -->
+
+The setup wizard automatically detects the required packages. In case one of them is missing,
+e.g. a PHP module, please install the package, restart your webserver and reload the setup page.
+
+<!-- {% if sles %} -->
+!!! note
+
+ If you're using php-fpm on SLES 15 SP2 onwards, `/etc/icingaweb2` may not be writable.
+ That's because the default systemd unit file for php-fpm has `ProtectSystem=full`
+ enabled. You want to lookup/add the systemd setting `ReadWritePaths=` in this case and
+ add `/etc/icingaweb2` to it. Alternatively you can also define a different configuration
+ directory using the environment variable `ICINGAWEB_CONFIGDIR`.
+<!-- {% endif %} -->
+
+<!-- {% if centos or rhel or amazon_linux %} -->
+!!! note
+
+ If you have SELinux enabled, please ensure to either have the selinux package for Icinga Web 2 installed, or disable it.
+<!-- {% endif %} -->
+
+<!-- {% else %} --><!-- {# end from_source elif #} -->
+<!-- {% if not icingaDocs %} -->
+## Installing Icinga Web 2 from Source <a id="installing-from-source"></a>
+<!-- {% endif %} -->
+
+Although the preferred way of installing Icinga Web 2 is to use packages, it is also possible to install Icinga Web 2
+directly from source.
+
+### Getting the Source <a id="getting-the-source"></a>
+
+First of all, you need to download the sources.
+
+Git clone:
+
+```bash
+cd /usr/share/
+git clone https://github.com/Icinga/icingaweb2.git icingaweb2
+```
+
+Tarball download (latest [release](https://github.com/Icinga/icingaweb2/releases/latest)):
+
+```bash
+cd /usr/share
+wget https://github.com/Icinga/icingaweb2/archive/v2.9.5.zip
+unzip v2.9.5.zip
+mv icingaweb2-2.9.5 icingaweb2
+```
+
+### Installing Requirements from Source <a id="installing-from-source-requirements"></a>
+
+You will need to install certain dependencies depending on your setup:
+
+* [Icinga 2](https://github.com/Icinga/icinga2) and [Icinga DB](https://github.com/Icinga/icingadb) to
+ monitor your infrastructure
+* A web server, e.g. Apache or Nginx
+* PHP version ≥ 7.2
+* [Icinga PHP Library (ipl)](https://github.com/Icinga/icinga-php-library) (≥ 0.13)
+* [Icinga PHP Thirdparty](https://github.com/Icinga/icinga-php-thirdparty) (≥ 0.12)
+* The following PHP modules must be installed: cURL, json, gettext, fileinfo, intl, dom, OpenSSL and xml
+* The [pdfexport](https://github.com/Icinga/icingaweb2-module-pdfexport) module (≥0.10) is required for the
+ export to PDF
+* LDAP PHP library when using Active Directory or LDAP for authentication
+* MySQL or PostgreSQL PHP libraries
+
+The following example installs Apache2 as web server, MySQL as RDBMS and uses the PHP adapter for MySQL.
+Adopt the package requirements to your needs (e.g. adding ldap for authentication) and distribution.
+
+Example for RHEL/CentOS/Fedora:
+
+```bash
+yum install httpd mysql-server
+yum install php php-gd php-intl
+```
+
+The setup wizard will check the pre-requisites later on.
+
+
+### Installing Icinga Web 2 <a id="installing-from-source-example"></a>
+
+Choose a target directory and move Icinga Web 2 there.
+
+```bash
+mv icingaweb2 /usr/share/icingaweb2
+```
+
+### Configuring the Web Server <a id="configuring-web-server"></a>
+
+Use `icingacli` to generate web server configuration for either Apache or nginx.
+
+**Apache**:
+```bash
+./bin/icingacli setup config webserver apache --document-root /usr/share/icingaweb2/public
+```
+
+**nginx**:
+```bash
+./bin/icingacli setup config webserver nginx --document-root /usr/share/icingaweb2/public
+```
+
+Save the output as new file in your webserver's configuration directory.
+
+Example for Apache on RHEL or CentOS:
+```bash
+./bin/icingacli setup config webserver apache --document-root /usr/share/icingaweb2/public > /etc/httpd/conf.d/icingaweb2.conf
+```
+
+Example for Apache on SUSE:
+```bash
+./bin/icingacli setup config webserver apache --document-root /usr/share/icingaweb2/public > /etc/apache2/conf.d/icingaweb2.conf
+```
+
+Example for Apache on Debian Jessie:
+```bash
+./bin/icingacli setup config webserver apache --document-root /usr/share/icingaweb2/public > /etc/apache2/conf-available/icingaweb2.conf
+a2enconf icingaweb2
+```
+
+Example for Apache on Alpine Linux:
+```bash
+icingacli setup config webserver apache --document-root /usr/share/webapps/icingaweb2/public > /etc/apache2/conf.d/icingaweb2.conf
+```
+### Preparing Icinga Web 2 Setup <a id="preparing-web-setup-from-source"></a>
+
+You can set up Icinga Web 2 quickly and easily with the Icinga Web 2 setup wizard which is available the first time
+you visit Icinga Web 2 in your browser. Please follow the steps listed below for preparing the web setup.
+
+Because both web and CLI must have access to configuration and logs, permissions will be managed using a special
+system group. The web server user and CLI user have to be added to this system group.
+
+Add the system group `icingaweb2` in the first place.
+
+**Fedora, RHEL, CentOS, SLES and OpenSUSE**:
+```bash
+groupadd -r icingaweb2
+```
+
+**Debian and Ubuntu**:
+```bash
+addgroup --system icingaweb2
+```
+
+Add your web server's user to the system group `icingaweb2`
+and restart the web server:
+
+**Fedora, RHEL and CentOS**:
+```bash
+usermod -a -G icingaweb2 apache
+service httpd restart
+```
+
+**SLES and OpenSUSE**:
+```bash
+usermod -A icingaweb2 wwwrun
+service apache2 restart
+```
+
+**Debian and Ubuntu**:
+```bash
+usermod -a -G icingaweb2 www-data
+service apache2 restart
+```
+
+**Alpine Linux**:
+```bash
+gpasswd -a apache icingaweb2
+rc-service apache2 restart
+```
+
+
+Use `icingacli` to create the configuration directory which defaults to **/etc/icingaweb2**:
+```bash
+./bin/icingacli setup config directory
+```
+
+
+When using the web setup you are required to authenticate using a token. In order to generate a token use the
+`icingacli`:
+```bash
+./bin/icingacli setup token create
+```
+
+In case you do not remember the token you can show it using the `icingacli`:
+```bash
+./bin/icingacli setup token show
+```
+
+### Icinga Web 2 Setup Wizard <a id="web-setup-from-source-wizard"></a>
+
+Finally visit Icinga Web 2 in your browser to access the setup wizard and complete the installation:
+`/icingaweb2/setup`.
+
+Paste the previously generated token and follow the steps on-screen. Then you are done here.
+
+If you prefer to set up the configuration manually, follow the
+[Icinga Web 2 Manual Configuration instructions](20-Advanced-Topics.md#web-setup-manual-from-source-config)

+# Resources <a id="resources"></a>
+
+The configuration file `resources.ini` contains information about data sources that can be referenced in other
+configuration files. This allows you to manage all data sources at one central place, avoiding the need to edit several
+different files when the information about a data source changes.
+
+## Configuration <a id="resources-configuration"></a>
+
+Each section in `resources.ini` represents a data source with the section name being the identifier used to
+reference this specific data source. Depending on the data source type, the sections define different directives.
+The available data source types are `db`, `ldap` and `ssh` which will described in detail in the following
+paragraphs.
+
+Type | Description

+
+The name in brackets defines the resource name.
+
+```
+[icingaweb-mysql-tcp]
+type = db
+db = mysql
+host = 127.0.0.1
+port = 3306
+username = icingaweb
+password = icingaweb
+dbname = icingaweb
+
+[icingaweb-mysql-socket]
+type = db
+db = mysql
+host = localhost
+username = icingaweb
+password = icingaweb
+dbname = icingaweb
+
+[icingaweb-pgsql-socket]
+type = db
+db = pgsql
+host = /var/run/postgresql
+port = 5432
+username = icingaweb
+password = icingaweb
+dbname = icingaweb
+```
+
+### LDAP <a id="resources-configuration-ldap"></a>
+
+A LDAP resource represents a tree in a LDAP directory.
+LDAP is usually used for authentication and authorization.
+
+Option | Description
+-------------------------|-----------------------------------------------
+type | **Required.** Specifies the resource type. Must be set to `ldap`.
+hostname | **Required.** Connect to the LDAP server on the given host. You can also provide multiple hosts separated by a space.
+port | **Required.** Port number to use for the connection.

+disable_server_side_sort | **Optional.** Disable server side sorting. Defaults to automatic detection whether the server supports this.
+
+#### Server Side Sorting <a id="ldap-server-side-sort"></a>
+
+Icinga Web automatically detects whether the LDAP server supports server side sorting.
+If that is not the case, results get sorted on the client side.
+There are LDAP servers though which report that they support this feature in general but have it disabled for certain
+fields. This may lead to failures. With `disable_server_side_sort` it is possible to disable server side sorting and it
+has precedence over the automatic detection.
+
+#### Example <a id="resources-configuration-ldap-example"></a>
+
+The name in brackets defines the resource name.
+
+```
+[ad]
+type = ldap
+hostname = localhost
+port = 389
+root_dn = "ou=people,dc=icinga,dc=org"
+bind_dn = "cn=admin,ou=people,dc=icinga,dc=org"
+bind_pw = admin
+```
+
+### SSH <a id="resources-configuration-ssh"></a>
+
+A SSH resource contains the information about the user and the private key location, which can be used for the key-based
+ssh authentication.

+# Authentication <a id="authentication"></a>
+
+You can authenticate against Active Directory, LDAP, a MySQL or a PostgreSQL database or delegate
+authentication to the web server.
+
+Authentication methods can be chained to set up fallback authentication methods
+or if users are spread over multiple places.
+
+## Configuration <a id="authentication-configuration"></a>
+
+Navigate into **Configuration > Application > Authentication **.
+
+Authentication methods are configured in the `/etc/icingaweb2/authentication.ini` file.
+
+Each section in the authentication configuration represents a single authentication method.
+
+The order of entries in the authentication configuration determines the order of the authentication methods.
+If the current authentication method errors or if the current authentication method does not know the account being
+authenticated, the next authentication method will be used.
+
+## External Authentication <a id="authentication-configuration-external-authentication"></a>
+
+Authentication to the web server can be delegated with the `autologin` section
+which specifies an external backend.
+
+Option | Description
+-------------------------|-----------------------------------------------
+backend | **Required.** Specifies the backend type. Must be set to `external`.
+strip\_username\_regexp | **Optional.** Regular expression to strip off specific user name parts.
+
+Example:
+
+```
+# vim /etc/icingaweb2/authentication.ini
+
+[autologin]
+backend = external
+```
+
+If your web server is not configured for authentication though, the `autologin` section has no effect.
+
+### Example Configuration for Apache and Basic Authentication <a id="authentication-configuration-external-authentication-example"></a>
+
+The following example will show you how to enable external authentication in Apache
+using basic authentication.
+
+#### Create Basic Auth User <a id="authentication-configuration-external-authentication-example-user"></a>
+
+You can use the tool `htpasswd` to generate basic authentication credentials. This example writes the
+user credentials into the `.http-users` file.
+
+The following command creates a new file which adds the user `icingaadmin`.
+`htpasswd` will prompt you for a password.
+If you want to add more users to the file you have to omit the `-c` switch to not overwrite the file.
+
+```
+sudo htpasswd -c /etc/icingaweb2/.http-users icingaadmin
+```
+
+#### Apache Configuration <a id="authentication-configuration-external-authentication-example-apache"></a>
+
+Add the following configuration to the `&lt;Directory&gt;` directive in the `icingaweb2.conf` web server
+configuration file.
+
+```
+AuthType Basic
+AuthName "Icinga Web 2"
+AuthUserFile /etc/icingaweb2/.http-users
+Require valid-user
+```
+
+Restart your web server to apply the changes.
+
+Example on CentOS 7:
+
+```
+systemctl restart httpd
+```
+
+## Active Directory or LDAP Authentication <a id="authentication-configuration-ad-or-ldap-authentication"></a>
+
+If you want to authenticate against Active Directory or LDAP, you have to define an
+[LDAP resource](04-Resources.md#resources-configuration-ldap).
+This is referenced as data source for the Active Directory or LDAP configuration method.
+
+### LDAP <a id="authentication-configuration-ldap-authentication"></a>
+
+Option | Description
+-------------------------|-----------------------------------------------
+backend | **Required.** Specifies the backend type. Must be set to `ldap`.
+resource | **Required.** The name of the LDAP resource defined in [resources.ini](04-Resources.md#resources).
+user\_class | **Optional.** LDAP user class. Defaults to `inetOrgPerson`.
+user\_name\_attribute | **Optional.** LDAP attribute which contains the username. Defaults to `uid`.
+filter | **Optional.** LDAP search filter. Requires `user_class` and `user_name_attribute`.
+
+> **Note for SELinux**
+>
+> If you run into problems connecting with LDAP and have SELinux enabled, take a look [here](90-SELinux.md#selinux-optional-booleans).
+
+Example:
+
+```
+# vim /etc/icingaweb2/authentication.ini
+
+[auth_ldap]
+backend = ldap
+resource = my_ldap
+user_class = inetOrgPerson
+user_name_attribute = uid
+filter = "memberOf=cn=icinga_users,cn=groups,cn=accounts,dc=icinga,dc=org"
+```
+
+If `user_name_attribute` specifies multiple values all of them must be unique.
+Please keep in mind that a user will be logged in with the exact user id used to authenticate
+with Icinga Web 2 (e.g. an alias) ignoring the actual primary user id.
+
+### Active Directory <a id="authentication-configuration-ad-authentication"></a>
+
+Option | Description
+-------------------------|-----------------------------------------------
+backend | **Required.** Specifies the backend type. Must be set to `msldap`.
+resource | **Required.** The name of the LDAP resource defined in [resources.ini](04-Resources.md#resources).
+user\_class | **Optional.** LDAP user class. Defaults to `user`.
+user\_name\_attribute | **Optional.** LDAP attribute which contains the username. Defaults to `sAMAccountName`.
+filter | **Optional.** LDAP search filter. Requires `user_class` and `user_name_attribute`.
+
+Example:
+
+```
+# vim /etc/icingaweb2/authentication.ini
+
+[auth_ad]
+backend = msldap
+resource = my_ad
+```
+
+## Database Authentication <a id="authentication-configuration-db-authentication"></a>
+
+If you want to authenticate against a MySQL or a PostgreSQL database, you have to define a
+[database resource](04-Resources.md#resources-configuration-database) which will be referenced as data source for the database
+authentication method.
+
+Option | Description
+-------------------------|-----------------------------------------------
+backend | **Required.** Specifies the backend type. Must be set to `db`.
+resource | **Required.** The name of the database resource defined in [resources.ini](04-Resources.md#resources). |
+
+Example:
+
+```
+# vim /etc/icingaweb2/authentication.ini
+
+[auth_db]
+backend = db
+resource = icingaweb-mysql
+```
+
+Please read [this chapter](20-Advanced-Topics.md#advanced-topics-authentication-tips-manual-user-database-auth)
+in order to manually create users directly inside the database.
+
+
+## Groups <a id="authentication-configuration-groups"></a>
+
+Navigate into **Configuration > Application > Authentication **.
+
+Group configuration is stored in the `/etc/icingaweb2/groups.ini` file.
+

+user\_class | **Optional.** LDAP user class. Defaults to `inetOrgPerson` with `msldap` and `user` with `ldap`.
+user\_name\_attribute | **Optional.** LDAP attribute which contains the username. Defaults to `sAMAccountName` with `msldap` and `uid` with `ldap`.
+user\_base\_dn | **Optional.** The path where users can be found on the LDAP server.
+base_dn | **Optional.** LDAP base dn for groups. Leave empty to select all groups available using the specified resource.
+group\_class | **Optional.** LDAP group class. Defaults to `group`.
+group\_member\_attribute | **Optional.** LDAP attribute where a group's members are stored. Defaults to `member`.
+group\_name\_attribute | **Optional.** LDAP attribute which contains the groupname. Defaults to `sAMAccountName` with `msldap` and `gid` with `ldap`.

+resource = "auth_ad"
+group_class = "group"
+user_class = "user"
+user_name_attribute = "userPrincipalName"
+```
+
+Example for Active Directory using the group backend resource `ad_company`.
+It also references the defined user backend resource `ad_users_company`.
+
+```
+# vim /etc/icingaweb2/groups.ini
+
+[ad_groups_company]
+backend = "msldap"
+resource = "ad_company"
+user_backend = "ad_users_company"

+base_dn = "ou=Icinga,ou=Groups,dc=company,dc=com"
+```
+
+### Database Groups <a id="authentication-configuration-groups-database"></a>
+
+Option | Description
+-------------------------|-----------------------------------------------
+backend | **Required.** Specifies the backend type. Must be set to `db`.
+resource | **Required.** The name of the database resource defined in [resources.ini](04-Resources.md#resources).
+
+Example:
+
+```
+# vim /etc/icingaweb2/groups.ini
+
+[icingaweb2]
+backend = "db"
+resource = "icingaweb_db"
+```
+
+
+## Domain-aware Authentication <a id="domain-aware-auth"></a>
+
+If there are multiple LDAP/AD authentication backends with distinct domains, you should make Icinga Web 2 aware of the
+domains. This is possible since version 2.5 and can be done by configuring each LDAP/AD backend's domain. You can also
+use the GUI for this purpose. This enables you to automatically discover a suitable value based on your LDAP server's
+configuration. (AD: NetBIOS name, other LDAP: domain in DNS-notation)
+
+**Example:**
+
+```
+# vim /etc/icingaweb2/authentication.ini
+
+[auth_icinga]
+backend = ldap
+resource = icinga_ldap
+user_class = inetOrgPerson
+user_name_attribute = uid
+filter = "memberOf=cn=icinga_users,cn=groups,cn=accounts,dc=icinga,dc=com"
+domain = "icinga.com"
+
+[auth_example]
+backend = msldap
+resource = example_ad
+domain = EXAMPLE
+```
+
+If you configure the domains like above, the icinga.com user "jdoe" will have to log in as "jdoe@icinga.com" and the
+EXAMPLE employee "rroe" will have to log in as "rroe@EXAMPLE". They could also log in as "EXAMPLE\\rroe", but this gets
+converted to "rroe@EXAMPLE" as soon as the user logs in.
+
+> **Caution!**
+>
+> Enabling domain-awareness or changing domains in existing setups requires migration of the usernames in the Icinga Web 2
+> configuration. Consult `icingacli --help migrate config users` for details.
+
+### Default Domain <a id="default-auth-domain"></a>
+
+For the sake of simplicity a default domain can be configured (in `config.ini`).
+
+**Example:**
+
+```
+# vim /etc/icingaweb2/config.ini
+
+[authentication]
+default_domain = "icinga.com"
+```
+
+If you configure the default domain like above, the user "jdoe@icinga.com" will be able to just type "jdoe" as username
+while logging in.
+
+### How it works <a id="domain-aware-auth-process"></a>
+
+### Active Directory <a id="domain-aware-auth-ad"></a>
+
+When the user "jdoe@ICINGA" logs in, Icinga Web 2 walks through all configured authentication backends until it finds
+one which is responsible for that user -- e.g. an Active Directory backend with the domain "ICINGA". Then Icinga Web 2
+asks that backend to authenticate the user with the sAMAccountName "jdoe".
+
+### SQL Database <a id="domain-aware-auth-sqldb"></a>
+
+When the user "jdoe@icinga.com" logs in, Icinga Web 2 walks through all configured authentication backends until it
+finds one which is responsible for that user -- e.g. a MySQL backend (SQL database backends aren't domain-aware). Then
+Icinga Web 2 asks that backend to authenticate the user with the username "jdoe@icinga.com".

+# Security
+
+Access control is a vital part of configuring Icinga Web 2 securely. It is important that not every user that has
+access to Icinga Web 2 can perform any action or see any host and service. Allow only a small group of administrators
+to change the Icinga Web 2 configuration to prevent mis-configuration and security breaches. Define different rules
+to users and groups of users which should only see a part of the monitoring environment they're in charge of.
+
+This chapter will describe how to configure such rules in Icinga Web 2 and how permissions, refusals, restrictions
+and role inheritance work.
+
+## Basics
+
+Icinga Web 2 access control is done by defining **roles** that associate privileges with **users** and **groups**.
+Privileges of a role consist of **permissions**, **refusals** and **restrictions**. A role can **inherit** privileges
+from another role.
+
+### Role Memberships
+
+A role is tied to users or groups of users. Upon login, a user's roles are identified by the username or names of
+groups the user is a member of.
+
+> **Note**
+>
+> Since Icinga Web 2, users in the Icinga configuration and the web authentication are separated, to allow use of
+> external authentication providers. This means that users and groups defined in the Icinga configuration are not
+> available to Icinga Web 2. It uses its own authentication backend to fetch users and groups from,
+> [which must be configured separately](05-Authentication.md#authentication).
+
+### Privileges
+
+Permissions are used to grant access. Whether this means that a user can see a certain area or perform a distinct
+action is fully up to the permission in question. Without granting a permission, the user will lack access and won't
+see the area or perform the action.
+
+Refusals are used to deny access. So they're the exact opposite of permissions. Most permissions can be refused.
+Refusing a permission will block the user's access no matter if another role grants the permission. Refusals
+override permissions.
+
+Restrictions are expressions that limit access. What this exactly means is up to how the restriction is being utilized.
+Without any restriction, a user is supposed to see *everything*. A user that occupies multiple roles, which all define
+a restriction of the same type, will see *more*.
+
+## Roles
+
+A user can occupy multiple roles. Permissions and restrictions stack up in this case, thus will grant *more* access.
+Refusals still override permissions however. A refusal of one role negates the granted permission of any other role.
+
+### Configuration
+
+Roles can be changed either through the UI, by navigating to the page **Configuration > Authentication > Roles**,
+or by editing the configuration file `/etc/icingaweb2/roles.ini`.
+
+#### Example
+
+The following shows a role definition from the configuration file mentioned above:
+
+```
+[winadmin]
+users = "jdoe, janedoe"
+groups = "admin"
+permissions = "config/*, module/monitoring, monitoring/commands/schedule-check"
+refusals = "config/authentication"
+monitoring/filter/objects = "host_name=*win*"
+```
+
+This describes a role with the name `winadmin`. The users `jdoe` and `janedoe` are members of it. Just like the
+members of group `admin` are. Full configuration access is granted, except of the authentication configuration,
+which is forbidden. It also grants access to the *monitoring* module which includes the ability to re-schedule
+checks, but only on objects related to hosts whose name contain `win`.
+
+#### Syntax
+
+Each role is defined as a section, with the name of the role as section name. The following
+options can be defined for each role in a default Icinga Web 2 installation:
+
+Name | Description
+--------------------------|-----------------------------------------------
+parent | The name of the role from which to inherit privileges.
+users | Comma-separated list of **usernames** that should occupy this role.
+groups | Comma-separated list of **group names** whose users should occupy this role.
+permissions | Comma-separated list of **permissions** granted by this role.
+refusals | Comma-separated list of **permissions** refused by this role.
+unrestricted | If set to `1`, owners of this role are not restricted in any way (Default: `0`)
+monitoring/filter/objects | **Filter expression** that restricts the access to monitoring objects.
+
+### Administrative Roles
+
+Roles that have the wildcard `*` as permission, have full access and don't need any further permissions. However,
+they are still affected by refusals.
+
+Unrestricted roles are supposed to allow users to access data without being limited to a subset of it. Once a user
+occupies an unrestricted role, restrictions of the same and any other role are ignored.
+
+### Inheritance
+
+A role can inherit privileges from another role. Privileges are then combined the same way as if a user occupies
+all roles in the inheritance path. Or to rephrase that, each role shares its members with all of its parents.
+
+## Permissions
+
+Each permission in Icinga Web 2 is denoted by a **namespaced key**, which is used to group permissions. All permissions
+that affect the configuration of Icinga Web 2, are in a namespace called **config**, while all configuration options
+that affect modules are covered by the permission `config/modules`.
+
+**Wildcards** can be used to grant all permissions in a certain namespace. The permission `config/*` grants access to
+all configuration options. Just specifying a wildcard `*` will grant all permissions.
+
+Access to modules is restricted to users who have the related module permission granted. Icinga Web 2 provides
+a module permission in the format `module/<moduleName>` for each installed module.
+
+### General Permissions
+
+Name | Permits
+-----------------------------|-----------------------------------------------
+\* | allow everything, including module-specific permissions
+application/announcements | allow to manage announcements
+application/log | allow to view the application log
+config/\* | allow full config access
+config/access-control/\* | allow to fully manage access control
+config/access-control/groups | allow to manage groups
+config/access-control/roles | allow to manage roles
+config/access-control/users | allow to manage user accounts
+config/general | allow to adjust the general configuration
+config/modules | allow to enable/disable and configure modules
+config/navigation | allow to view and adjust shared navigation items
+config/resources | allow to manage resources
+user/\* | allow all account related functionalities
+user/application/stacktraces | allow to adjust in the preferences whether to show stacktraces
+user/password-change | allow password changes in the account preferences
+user/share/navigation | allow to share navigation items
+module/`<moduleName>` | allow access to module `<moduleName>` (e.g. `module/monitoring`)
+
+### Monitoring Module Permissions
+
+The built-in monitoring module defines an additional set of permissions, that
+is described in detail in the monitoring module documentation.
+
+## Restrictions
+
+Restrictions can be used to define what a user can see by specifying an expression that applies to a defined set of
+data. By default, when no restrictions are defined, a user will be able to see the entire data that is available.
+
+The syntax of the expression used to define a particular restriction varies. This can be a comma-separated list of
+terms, or [a full-blown filter](06-Security.md#filter-expressions). For more details on particular restrictions,
+check the table below or the module's documentation providing the restriction.
+
+### General Restrictions
+
+Name | Applies to
+--------------------------|------------------------------------------------------------------------------------------
+application/share/users | which users a user can share navigation items with (comma-separated list of usernames)
+application/share/groups | which groups a user can share navigation items with (comma-separated list of group names)
+
+### Username placeholder
+
+It is possible to reference the local username (without the domain part) of the user in restrictions. To accomplish
+this, put the macro `$user.local_name$` in the restriction where you want it to appear.
+
+This can come in handy if you have e.g. an attribute on hosts or services defining which user is responsible for it:
+`_host_deputy=$user.local_name$|_service_deputy=$user.local_name$`
+
+### Filter Expressions
+
+Filters operate on columns. A complete list of all available filter columns on hosts and services can be found in
+the monitoring module documentation.
+
+Any filter expression that is allowed in the filtered view, is also an allowed filter expression.
+This means, that it is possible to define negations, wildcards, and even nested
+filter expressions containing AND and OR-Clauses.
+
+The filter expression will be **implicitly** added as an **AND-Clause** to each query on
+the filtered data. The following shows the filter expression `host_name=*win*` being applied on `monitoring/filter/objects`.
+
+
+Regular filter query:
+
+ AND-- service_problem = 1
+ |
+ +--- service_handled = 0
+
+
+With our restriction applied, any user affected by this restrictions will see the
+results of this query instead:
+
+
+ AND-- host_name = *win*
+ |
+ +--AND-- service_problem = 1
+ |
+ +--- service_handled = 0
+
+#### Stacking Filters
+
+When multiple roles assign restrictions to the same user, either directly or indirectly
+through a group, all filters will be combined using an **OR-Clause**, resulting in the final
+expression:
+
+
+ AND-- OR-- $FILTER1
+ | |
+ | +-- $FILTER2
+ | |
+ | +-- $FILTER3
+ |
+ +--AND-- service_problem = 1
+ |
+ +--- service_handled = 0
+
+
+As a result, a user is be able to see hosts that are matched by **ANY** of
+the filter expressions. The following examples will show the usefulness of this behavior:
+
+#### Example 1: Negation
+
+```
+[winadmin]
+groups = "windows-admins"
+monitoring/filter/objects = "host_name=*win*"
+```
+
+Will display only hosts and services whose host name contains **win**.
+
+```
+[webadmin]
+groups = "web-admins"
+monitoring/filter/objects = "host_name!=*win*"
+```
+
+Will only match hosts and services whose host name does **not** contain **win**
+
+Notice that because of the behavior of two stacking filters, a user that is member of **windows-admins** and **web-admins**, will now be able to see both, Windows and non-Windows hosts and services.
+
+#### Example 2: Hostgroups
+
+```
+[unix-server]
+groups = "unix-admins"
+monitoring/filter/objects = "(hostgroup_name=bsd-servers|hostgroup_name=linux-servers)"
+```
+
+This role allows all members of the group unix-admins to see hosts and services
+that are part of the host-group linux-servers or the host-group bsd-servers.

+# Modules
+
+## Installation
+
+A module should be installed in one of the [configured module paths](03-Configuration.md#general-configuration).
+The default path in most installations is `/usr/share/icingaweb2/modules`.
+
+Each directory in there contains the files for a particular module. The directory's name has to be the one
+that is provided by the module's documentation. If there is none provided, it is usually the name of the
+module in all lowercase. Some modules may use a name prefixed with `icingaweb2-module-`. If this is the case,
+the directory's name should be that, but without the prefix.
+(e.g. `icingaweb2-module-map` turns into `/usr/share/icingaweb2/modules/map`)
+
+> **Note:**
+>
+> Remember to ensure that your web-server can access those files. Though, read permission only.
+
+Once a module's files are in place, it needs to be enabled first before it can be used. This can either be done in
+the UI at `Configuration -> Modules` or by using the icingacli: `icingacli module enable map`
+
+In order for other non-admin users to access the module's functionality, it is required to permit access first.
+This is done by granting the permission `module/<module-name>`. (e.g. `module/map`)
+
+### Module Specific Instructions
+
+A module may require further installation steps. Whether these need to be performed before enabling the module,
+should be provided by the module's documentation. In any case, don't forget to apply these as well, otherwise
+the module will most likely not function correctly.
+
+### Examples
+
+There are sample installation instructions provided for your convenience:
+
+**Sample Tarball installation**
+
+```sh
+MODULE_NAME="map"
+MODULE_VERSION="v1.1.0"
+MODULE_AUTHOR="nbuchwitz"
+MODULES_PATH="/usr/share/icingaweb2/modules"
+MODULE_PATH="${MODULES_PATH}/${MODULE_NAME}"
+RELEASES="https://github.com/${MODULE_AUTHOR}/icingaweb2-module-${MODULE_NAME}/archive"
+mkdir "$MODULE_PATH" \
+&& wget -q $RELEASES/${MODULE_VERSION}.tar.gz -O - \
+ | tar xfz - -C "$MODULE_PATH" --strip-components 1
+icingacli module enable "${MODULE_NAME}"
+```
+
+**Sample GIT installation**
+
+```sh
+MODULE_NAME="map"
+MODULE_VERSION="v1.1.0"
+MODULE_AUTHOR="nbuchwitz"
+REPO="https://github.com/${MODULE_AUTHOR}/icingaweb2-module-${MODULE_NAME}"
+MODULES_PATH="/usr/share/icingaweb2/modules"
+git clone ${REPO} "${MODULES_PATH}/${MODULE_NAME}" --branch "${MODULE_VERSION}"
+icingacli module enable "${MODULE_NAME}"
+```
+
+## Configuration
+
+A module may also require configuration. Most modules provide additional tabs at their configuration page.
+This is accessible in the UI at `Configuration -> Modules`. If not, and something isn't working, check the
+module's documentation again for hints.
+
+If you need access to a module's configuration files directly, they should be in a subdirectory `modules`
+of Icinga Web 2's configuration directory. That is usually `/etc/icingaweb2/modules`. Each directory in
+there should be named the same as its installation path. (e.g. `/etc/icingaweb2/modules/map`)

+
+## VirtualHost Configuration <a id="virtualhost-configuration"></a>
+
+This describes how to run Icinga Web 2 on your FQDN's `/` entry point without
+any redirect to `/icingaweb2`.
+
+### VirtualHost Configuration for Apache <a id="virtualhost-configuration-apache"></a>
+
+Use the setup CLI commands to generate the default Apache configuration which serves
+Icinga Web 2 underneath `/icingaweb2`.
+
+The next steps are to create the VirtualHost configuration:
+
+* Copy the `<Directory "/usr/share/icingaweb2/public">` into the main VHost configuration. Don't forget to correct the indent.
+* Set the `DocumentRoot` variable to look into `/usr/share/icingaweb2/public`
+* Modify the `RewriteBase` variable to use `/` instead of `/icingaweb2`
+
+Example on RHEL/CentOS:
+
+```
+vim /etc/httpd/conf.d/web.icinga.com.conf
+
+<VirtualHost *:80>
+ ServerName web.icinga.com
+
+ ## Vhost docroot
+ # modified for Icinga Web 2
+ DocumentRoot "/usr/share/icingaweb2/public"
+
+ ## Rewrite rules
+ RewriteEngine On
+
+ <Directory "/usr/share/icingaweb2/public">
+ Options SymLinksIfOwnerMatch
+ AllowOverride None
+
+ <IfModule mod_authz_core.c>
+ # Apache 2.4
+ <RequireAll>
+ Require all granted
+ </RequireAll>
+ </IfModule>
+
+ <IfModule !mod_authz_core.c>
+ # Apache 2.2
+ Order allow,deny
+ Allow from all
+ </IfModule>
+
+ SetEnv ICINGAWEB_CONFIGDIR "/etc/icingaweb2"
+
+ EnableSendfile Off
+
+ <IfModule mod_rewrite.c>
+ RewriteEngine on
+ # modified base
+ RewriteBase /
+ RewriteCond %{REQUEST_FILENAME} -s [OR]
+ RewriteCond %{REQUEST_FILENAME} -l [OR]
+ RewriteCond %{REQUEST_FILENAME} -d
+ RewriteRule ^.*$ - [NC,L]
+ RewriteRule ^.*$ index.php [NC,L]
+ </IfModule>
+
+ <IfModule !mod_rewrite.c>
+ DirectoryIndex error_norewrite.html
+ ErrorDocument 404 /error_norewrite.html
+ </IfModule>
+ </Directory>
+</VirtualHost>
+```
+
+Reload Apache and open the FQDN in your web browser.
+
+```
+systemctl reload httpd
+```
+
+### Content Security Policy (CSP) <a id="advanced-topics-csp"></a>
+
+Elevate your security standards to an even higher level by enabling the [Content Security Policy (CSP)](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP) for Icinga Web.
+Enabling strict CSP can prevent your Icinga Web environment from becoming a potential target of [Cross-Site Scripting (XSS)](https://developer.mozilla.org/en-US/docs/Glossary/Cross-site_scripting)
+and data injection attacks. After enabling this feature Icinga Web defines all the required CSP headers. Subsequently,
+only content coming from Icinga Web's own origin is accepted, inline JS is prohibited, and inline CSS is accepted only
+if it contains the nonce set in the response header.
+
+We decided against enabling this by default as we cannot guarantee that all the modules out there will function correctly.
+Therefore, you have to manually enable this policy explicitly and accept the risks that this might break some of
+the Icinga Web modules. Icinga Web and all it's components listed below, on the other hand, fully support strict CSP. If
+that's not the case, please submit an issue on GitHub in the respective repositories.
+
+Here is a list of all Icinga Web components that are capable of strict CSP.
+
+| Name | CSP supported since |

+## Advanced Authentication Tips <a id="advanced-topics-authentication-tips"></a>
+
+### Manual User Creation for Database Authentication Backend <a id="advanced-topics-authentication-tips-manual-user-database-auth"></a>
+
+Icinga Web 2 v2.5+ uses the [native password hash algorithm](https://php.net/manual/en/faq.passwords.php)
+provided by PHP 5.6+.
+
+In order to generate a password, run the following command with the PHP CLI >= 5.6:
+
+```
+php -r 'echo password_hash("yourtopsecretpassword", PASSWORD_DEFAULT);'
+```
+
+Please note that the hashed output changes each time. This is expected.
+
+Insert the user into the database using the generated password hash.
+
+```
+INSERT INTO icingaweb_user (name, active, password_hash) VALUES ('icingaadmin', 1, '$2y$10$bEKU6.1bRYjE7wxktqfeO.IGV9pYAkDBeXEbjMFSNs26lKTI0JQ1q');
+```
+
+#### Puppet <a id="advanced-topics-authentication-tips-manual-user-database-auth-puppet"></a>
+
+Please do note that the `$` character needs to be escaped with a leading backslash in your
+Puppet manifests.
+
+Example from [puppet-icingaweb2](https://github.com/Icinga/puppet-icingaweb2):
+
+```
+ exec { 'create default user':
+ command => "mysql -h '${db_host}' -P '${db_port}' -u '${db_username}' -p'${db_password}' '${db_name}' -Ns -e 'INSERT INTO icingaweb_user (name, active, password_hash) VALUES (\"icingaadmin\", 1, \"\$2y\$10\$QnXfBjl1RE6TqJcY85ZKJuP9AvAV3ont9QihMTFQ/D/vHmAWaz.lG\")'",
+ refreshonly => true,
+ }
+```

+
+## Icinga Web 2 Manual Setup <a id="web-setup-manual-from-source"></a>
+
+If you have chosen not to run the setup wizard, you will need further knowledge
+about
+
+* manual creation of the Icinga Web 2 database `icingaweb2` including a default user (optional as authentication and session backend)
+* additional configuration for the application
+* additional configuration for the monitoring module (e.g. the IDO database and external command pipe from Icinga 2)
+
+This comes in handy if you are planning to deploy Icinga Web 2 automatically using
+Puppet, Ansible, Chef, etc.
+
+> **Warning**
+>
+> Read the documentation on the respective linked configuration sections before
+> deploying the configuration manually.
+>
+> If you are unsure about certain settings, use the setup wizard as described in the
+> [installation instructions](02-Installation.md) once and then collect the generated
+> configuration as well as sql dumps.
+
+### Icinga Web 2 Manual Database Setup <a id="web-setup-manual-from-source-database"></a>
+
+Create the database and add a new user as shown below for MySQL/MariaDB:
+
+```
+sudo mysql -p
+
+CREATE DATABASE icingaweb2;
+GRANT CREATE, SELECT, INSERT, UPDATE, DELETE, DROP, ALTER, CREATE VIEW, INDEX, EXECUTE ON icingaweb2.* TO 'icingaweb2'@'localhost' IDENTIFIED BY 'icingaweb2';
+quit
+
+mysql -p icingaweb2 < /usr/share/icingaweb2/schema/mysql.schema.sql
+```
+
+
+Then generate a new password hash as described in the [authentication docs](05-Authentication.md#authentication-configuration-db-setup)
+and use it to insert a new user called `icingaadmin` into the database.
+
+```
+mysql -p icingaweb2
+
+INSERT INTO icingaweb_user (name, active, password_hash) VALUES ('icingaadmin', 1, '$1$EzxLOFDr$giVx3bGhVm4lDUAw6srGX1');
+quit
+```
+
+### Icinga Web 2 Manual Configuration <a id="web-setup-manual-from-source-config"></a>
+
+
+[resources.ini](04-Resources.md#resources) providing the details for the Icinga Web 2 and
+Icinga 2 IDO database configuration. Example for MySQL:
+
+```
+vim /etc/icingaweb2/resources.ini
+
+[icingaweb2]
+type = "db"
+db = "mysql"
+host = "localhost"
+port = "3306"
+dbname = "icingaweb2"
+username = "icingaweb2"
+password = "icingaweb2"
+
+
+[icinga2]
+type = "db"
+db = "mysql"
+host = "localhost"
+port = "3306"
+dbname = "icinga"
+username = "icinga"
+password = "icinga"
+```
+
+[config.ini](03-Configuration.md#configuration) defining general application settings.
+
+```
+vim /etc/icingaweb2/config.ini
+
+[logging]
+log = "syslog"
+level = "ERROR"
+application = "icingaweb2"
+
+
+[preferences]
+type = "db"
+resource = "icingaweb2"
+```
+
+[authentication.ini](05-Authentication.md#authentication) for e.g. using the previously created database.
+
+```
+vim /etc/icingaweb2/authentication.ini
+
+[icingaweb2]
+backend = "db"
+resource = "icingaweb2"
+```
+
+
+[roles.ini](06-Security.md#security) granting the previously added `icingaadmin` user all permissions.
+
+```
+vim /etc/icingaweb2/roles.ini
+
+[admins]
+users = "icingaadmin"
+permissions = "*"
+```
+
+### Icinga Web 2 Manual Configuration Monitoring Module <a id="web-setup-manual-from-source-config-monitoring-module"></a>
+
+
+**config.ini** defining additional security settings.
+
+```
+vim /etc/icingaweb2/modules/monitoring/config.ini
+
+[security]
+protected_customvars = "*pw*,*pass*,community"
+```
+
+**backends.ini** referencing the Icinga 2 DB IDO resource.
+
+```
+vim /etc/icingaweb2/modules/monitoring/backends.ini
+
+[icinga2]
+type = "ido"
+resource = "icinga2"
+```
+
+**commandtransports.ini** defining the Icinga 2 API command transport.
+
+```
+vim /etc/icingaweb2/modules/monitoring/commandtransports.ini
+
+[icinga2]
+transport = "api"
+host = "localhost"
+port = "5665"
+username = "api"
+password = "api"
+```
+
+### Icinga Web 2 Manual Setup Login <a id="web-setup-manual-from-source-login"></a>
+
+Finally visit Icinga Web 2 in your browser to login as `icingaadmin` user: `/icingaweb2`.
+
+## Automating the Installation of Icinga Web 2 <a id="web-setup-automation"></a>
+
+Prior to creating your own script, please look into the official resources
+which may help you already:
+
+* [Puppet module](https://icinga.com/products/integrations/puppet/)
+* [Chef cookbook](https://icinga.com/products/integrations/chef/)
+
+If you are automating the installation of Icinga Web 2, you may want to skip the wizard and do things yourself.
+These are the steps you'd need to take assuming you are using MySQL/MariaDB. If you are using PostgreSQL please adapt
+accordingly. Note you need to have successfully completed the Icinga 2 installation, installed the Icinga Web 2 packages
+and all the other steps described above first.
+
+1. Install PHP dependencies: `php`, `php-intl`, `php-imagick`, `php-gd`, `php-mysql`, `php-curl`, `php-mbstring` used
+by Icinga Web 2.
+2. Create a database for Icinga Web 2, i.e. `icingaweb2`.
+3. Import the database schema: `mysql -D icingaweb2 < /usr/share/icingaweb2/schema/mysql.schema.sql`.
+4. Insert administrator user in the `icingaweb2` database:
+`INSERT INTO icingaweb_user (name, active, password_hash) VALUES ('admin', 1, '<hash>')`, where `<hash>` is the output
+of `php -r 'echo password_hash("yourtopsecretpassword", PASSWORD_DEFAULT);'`.
+5. Make sure the `ido-mysql` and `api` features are enabled in Icinga 2: `icinga2 feature enable ido-mysql` and
+`icinga2 feature enable api`.
+6. Generate Apache/nginx config. This command will print an apache config for you on stdout:
+`icingacli setup config webserver apache`. Similarly for nginx. You need to place that configuration in the right place,
+for example `/etc/apache2/sites-enabled/icingaweb2.conf`.
+7. Add `www-data` user to `icingaweb2` group if not done already (`usermod -a -G icingaweb2 www-data`).
+8. Create the Icinga Web 2 configuration in `/etc/icingaweb2`. The directory can be easily created with:
+`icingacli setup config directory`. This command ensures that the directory has the appropriate ownership and
+permissions. If you want to create the directory manually, make sure to chown the group to `icingaweb2` and set the
+access mode to `2770`.
+
+The structure of the configurations looks like the following:
+
+```
+/etc/icingaweb2/
+/etc/icingaweb2/authentication.ini
+/etc/icingaweb2/modules
+/etc/icingaweb2/modules/monitoring
+/etc/icingaweb2/modules/monitoring/config.ini
+/etc/icingaweb2/modules/monitoring/instances.ini
+/etc/icingaweb2/modules/monitoring/backends.ini
+/etc/icingaweb2/roles.ini
+/etc/icingaweb2/config.ini
+/etc/icingaweb2/enabledModules
+/etc/icingaweb2/enabledModules/monitoring
+/etc/icingaweb2/enabledModules/doc
+/etc/icingaweb2/resources.ini
+```
+
+Have a look [here](20-Advanced-Topics.md#web-setup-manual-from-source-config) for the contents of the files.
+
+## Kiosk Mode Configuration <a id="kiosk-mode"></a>
+
+Be aware that when you create a kiosk user every person who has access to the kiosk is able to perform tasks on it.
+Therefore you would need to create a user in the `roles.ini` in `/etc/icingaweb2/roles.ini`.
+
+```
+[kioskusers]
+users = "kiosk"
+```
+
+If you need special permissions you should add those permissions to the user via the admin account in icingaweb2 to the role of the kiosk user.
+
+For the Dashboard system where you want to display the kiosk you can add also the following part into the `icingaweb2.conf`.
+So it starts directly into the kiosk mode.
+If you want to show a specific Dashboard you can enforce this onto the kiosk user via the [enforceddashboard](https://github.com/Thomas-Gelf/icingaweb2-module-enforceddashboard) module.
+
+```
+<ifmodule mod_authz_core.c>
+ # Apache 2.4
+ SetEnvIf Remote_Addr "X.X.X.X" REMOTE_USER=kiosk
+ <requireall>
+ Require all granted
+ </requireall>
+</ifmodule>
+```
+
+Replace Remote_Addr with the IP where the kiosk user is accessing the Web to restrict further usage from other IPs.
+
+## Customizing the Landing Page <a id="landing-page"></a>
+
+The default landing page of `dashboard` can be customized using the environment variable `ICINGAWEB_LANDING_PAGE`.
+
+Example on RHEL/CentOS:
+
+```
+vim /etc/httpd/conf.d/web.icinga.com.conf
+
+<VirtualHost *:80>
+
+ ...
+
+ <Directory "/usr/share/icingaweb2/public">
+
+ ...
+
+ SetEnv ICINGAWEB_LANDING_PAGE "icingadb/services/grid?problems"
+
+ ...
+
+ </Directory>
+</VirtualHost>
+```

+# Hooks
+
+## ConfigFormEventsHook
+
+The `ConfigFormEventsHook` allows developers to hook into the handling of configuration forms. It provides three methods:
+
+* `appliesTo()`
+* `isValid()`
+* `onSuccess()`
+
+`appliesTo()` determines whether the hook should run for a given configuration form.
+Developers should use `instanceof` checks in order to decide whether the hook should run or not.
+If `appliesTo()` returns `false`, `isValid()` and `onSuccess()` won't get called for this hook.
+
+`isValid()` is called after the configuration form has been validated successfully.
+An exception thrown here indicates form errors and prevents the config from being stored.
+The exception's error message is shown in the frontend automatically.
+If there are multiple hooks indicating errors, every error will be displayed.
+
+`onSuccess()` is called after the configuration has been stored successfully.
+Form handling can't be interrupted here. Any exception will be caught, logged and notified.
+
+Hook example:
+
+```php
+namespace Icinga\Module\Acme\ProvidedHook;
+
+use Icinga\Application\Hook\ConfigFormEventsHook;
+use Icinga\Forms\ConfigForm;
+use Icinga\Forms\Security\RoleForm;
+
+class ConfigFormEvents extends ConfigFormEventsHook
+{
+ public function appliesTo(ConfigForm $form)
+ {
+ return $form instanceof RoleForm;
+ }
+
+ public function onSuccess(ConfigForm $form)
+ {
+ $this->updateMyModuleConfig();
+ }
+
+ protected function updateMyModuleConfig()
+ {
+ // ...
+ }
+}

+# Upgrading Icinga Web 2 <a id="upgrading"></a>
+
+Specific version upgrades are described below. Please note that upgrades are incremental. An upgrade from
+v2.6 to v2.8 requires to follow the instructions for v2.7 too.
+
+## Upgrading to Icinga Web 2.12.0
+
+**Database Schema**
+
+With the latest Icinga Web versions, you no longer need to manually import sql upgrade scripts. Icinga Web `>= 2.12`
+offers you the possibility to perform such migrations in an easy way. You can find and apply all pending migrations
+of your Icinga Web environment in the menu at `System -> Migrations`.
+
+You can still apply the `2.12.0.sql` upgrade script manually, depending on your database vendor.
+For package installations you can find this file in `/usr/share/icingaweb2/schema/*-upgrades/`.
+
+## Upgrading to Icinga Web 2.11.x
+
+**General**
+
+* Support for Internet Explorer 11 has been removed.
+* The Vagrant file and all its assets have been removed.
+
+**Database Schema**
+
+* Please apply the `v2.11.0.sql` upgrade script depending on your database vendor.
+ As of version `2.11.4`, upgrade scripts can be found at `/usr/share/icingaweb2/schema/*-upgrades/`.
+ Older versions install these files to `/usr/share/doc/icingaweb2/schema/*-upgrades/` for RPM-based systems
+ and `/usr/share/icingaweb2/etc/schema/*-upgrades/` for Debian or Ubuntu.
+
+**Breaking changes**
+
+* The `user:local_name` macro in restrictions has been removed. Use `user.local_name` now.
+* User preferences stored in INI files are not loaded anymore. Migrate yours with
+ `icingacli migrate preferences` before the upgrade, if you haven't already.
+
+**Framework changes affecting third-party code**
+
+* When loading library CSS assets, CSS files and LESS files are handled differently now. Only the latter
+ is parsed as LESS.
+* jQuery is not bundled anymore as it's now part of the library icinga-php-thirdparty v0.11.0. It's shipped there
+ in version 3.6.0. (Previously bundled was jQuery 3.4.1)
+* All the following classes have been removed:
+ * `Icinga\User\Preferences\Store\IniStore`: Preferences in INI files are not supported anymore.
+ * `Icinga\User\Preferences\Store\DbStore`: Its methods have been added to the `PreferencesStore` class.
+ * `Icinga\Util\String`: Use `Icinga\Util\StringHelper` instead.
+ * `Icinga\Util\Translator`: Use `\ipl\I18n\StaticTranslator::$instance` or `\ipl\I18n\Translation` instead.
+ * `Icinga\Module\Migrate\Clicommands\DashboardCommand`: Deleted without substitution.
+ * `Icinga\Web\Hook\TicketHook`: Use `Icinga\Application\Hook\TicketHook` instead.
+ * `Icinga\Web\Hook\GrapherHook`: Use `Icinga\Application\Hook\GrapherHook` instead.
+ * `Icinga\Module\Monitoring\Environment`: Not in use.
+ * `Icinga\Module\Monitoring\Backend`: Use `Icinga\Module\Monitoring\Backend\MonitoringBackend` instead.
+* All the following methods have been removed:
+ * `loader.js.addUrlFlag()`: Use `Icinga.Utils.addUrlFlag()` instead.
+ * `Url::setBaseUrl()`: Please create a new url from scratch instead.
+ * `Url::getBaseUrl()`: Use either `Url::getBasePath()` or `Url::getAbsoluteUrl()` now.
+ * `ApplicationBootstrap::setupZendAutoloader()`: Since it does nothing, all usages removed.
+ * `ApplicationBootstrap::listLocales()`: Use `\ipl\I18n\GettextTranslator::listLocales()` instead.
+ * `Module::registerHook()`: Use `provideHook()` instead.
+ * `Web::getMenu()`: Instantiate the menu class `new Menu()` directly instead.
+ * `AesCrypt::encryptToBase64()`: Use `AesCrypt::encrypt()` instead as it also returns a base64 encoded string.
+ * `AesCrypt::decryptFromBase64()`: Use `AesCrypt::decrypt()` instead as it also returns a base64 decoded string.
+ * `InlinePie::disableNoScript()`: Empty method.
+ * `SimpleQuery::paginate()`: Use `Icinga\Web\Controller::setupPaginationControl()` and/or `Icinga\Web\Widget\Paginator` instead.
+ * `LdapConnection::connect()`: The connection is established lazily since .. a long time.
+ * `MonitoredObject::matches()`: Use `$filter->matches($object)` instead.
+ * `MonitoredObject::fromParams()`: Deleted without substitution.
+ * `DataView::fromRequest()`: Use `$backend->select()->from($viewName)` instead.
+ * `DataView::sort()`: Use `DataView::order()` instead.
+ * `MonitoringBackend::createBackend()`: Use `MonitoringBackend::instance()` instead.
+ * `DbConnection::getConnection()`: Use `Connection::getDbAdapter()` instead.
+ * `DbQuery::renderFilter()`: Use `DbConnection::renderFilter()` instead.
+ * `DbQuery::whereToSql()`: Use `DbConnection::renderFilter()` instead.
+
+## Upgrading to Icinga Web 2 2.10.x
+
+**General**
+
+* The theme "solarized-dark" has been removed due to the introduction of the new default dark mode.
+
+**Deprecations**
+
+* Builtin support for PDF exports using the `dompdf` library will be dropped with version 2.12.
+ It is highly recommended to use [Icinga PDF Export](https://github.com/Icinga/icingaweb2-module-pdfexport)
+ instead.
+
+**Discontinued package updates**
+
+* We will stop offering major updates for Debian 9 (Stretch) starting with version 2.11.
+ However, versions 2.9 and 2.10 will continue to receive minor updates on this platform.
+
+[icinga.com](https://icinga.com/subscription/support-details/) provides an overview about
+currently supported distributions.
+
+**Framework changes affecting third-party code**
+
+* Asset support for modules (#3961) introduced with v2.8 has now been removed.
+* `expandable-toggle`-support has been removed. Use `class="collapsible" data-visible-height=0`
+ to achieve the same effect. (Available since v2.7.0)
+* The `.var()` LESS mixin and the LESS function `extract-variable-default` have been removed (introduced with v2.9)
+
+## Upgrading to Icinga Web 2 2.9.1
+
+**Database Schema**
+
+* Please apply the `v2.9.1.sql` upgrade script depending on your database vendor.
+ In package installations this file can be found in `/usr/share/doc/icingaweb2/schema/*-upgrades/`
+ (Debian/Ubuntu: `/usr/share/icingaweb2/etc/schema/*-upgrades/`).
+
+## Upgrading to Icinga Web 2 2.9.x
+
+**Installation**
+
+* Icinga Web 2 now requires the [Icinga PHP Library (ipl)](https://github.com/Icinga/icinga-php-library) (>= 0.6)
+ and [Icinga PHP Thirdparty](https://github.com/Icinga/icinga-php-thirdparty) (>= 0.10). Please make sure to
+ install both when upgrading. We provide packages for them and if you've installed Icinga Web 2 already by
+ package they should be installed automatically during the upgrade.
+* [Icinga Business Process Modelling](https://github.com/Icinga/icingaweb2-module-businessprocess/releases/tag/v2.3.1)
+ has been updated to v2.3.1. If you're using this module, this version is required when upgrading.
+
+**General**
+
+* For database connections to the IDO running on MySQL, a default charset (`latin1`) is now applied.
+ If you had previously problems with special characters and umlauts and you've set this charset
+ already manually, no change is required. However, if your IDO resource configuration has another
+ charset configured than this, it is highly recommended to clear this setting. Otherwise the default
+ won't apply and characters may still be shown incorrectly in the UI.
+
+**Database Schema**
+
+* Icinga Web 2 now permits its users to stay logged in. This requires a new database table.
+ * Please apply the `v2.9.0.sql` upgrade script depending on your database vendor.
+ In package installations this file can be found in `/usr/share/doc/icingaweb2/schema/*-upgrades/`
+ (Debian/Ubuntu: `/usr/share/icingaweb2/etc/schema/*-upgrades/`).
+
+**Breaking changes**
+
+* Password changes are not allowed by default anymore
+ * The fake refusal `no-user/password-change` has now been changed to a grant `user/password-change`.
+ Any user that had `no-user/password-change` previously still cannot change passwords. Though any
+ user that didn't have this *permission*, needs to be granted `user/password-change` now in order
+ to change passwords.
+
+**Deprecations**
+
+* Support for EOL PHP versions (5.6, 7.0, 7.1 and 7.2) will be removed with version 2.11
+* Support for Internet Explorer will be completely removed with version 2.11
+ * New features after v2.9 will already not (necessarily) be available in Internet Explorer
+* `user.local_name` replaces the `user:local_name` macro in restrictions, and the latter will be removed with
+ version 2.11
+* The configuration backend type `INI` is not configurable anymore. **A database is now mandatory.**
+ * Existing configurations using this configuration backend type will stop working with the
+ release of v2.11.
+ * To migrate your local user preferences to database, enable the `migrate` module and use the command
+ `icingacli migrate preferences`. If you already setup the configuration database, it will work right
+ away. If not, pass it the resource you'd like to use as configuration database with `--resource=`.
+ * Note that this only applies to user preferences. Other configurations are still stored
+ in `.ini` files. (#3770)
+* The Vagrant file and all its assets will be removed with version 2.11
+
+**Framework changes affecting third-party code**
+
+* The `jquery-migrate` compatibility layer for Javascript code working with jQuery 2.x has been removed.
+ It has been introduced with v2.7 when we upgraded jQuery to v3.4.1 in order to allow module developers
+ a seamless upgrade chance. If a module still has UI glitches after an upgrade to v2.9, please contact
+ the module developer.
+* The method `getHtmlForEvent` of the `EventDetailsExtensionHook` previously received the host or service
+ object of an event. Now the actual event object is passed to it instead.
+* Asset support for modules (#3961) introduced with v2.8 has now been deprecated in favor of library
+ support (#4272) and will be removed with v2.10. We don't expect broad usage of this feature since
+ it's been introduced with the latest major version, so it's already being removed with the next one.
+
+## Upgrading to Icinga Web 2 2.8.x
+
+**Changes in packaging and dependencies**
+
+Valid for distributions:
+
+* RHEL / CentOS 7
+ * Upgrade to PHP 7.3 via RedHat SCL
+
+After upgrading to version 2.8.0 you'll get the new `rh-php73` dependency installed. This is a drop-in replacement
+for the previous `rh-php71` dependency and only requires the setup of a new fpm service and possibly some copying
+of customized configurations.
+
+**php.ini or php-fpm settings** you have tuned in the past need to be copied over to the new path:
+
+From `/etc/opt/rh/rh-php71/` to `/etc/opt/rh/rh-php73/`.
+
+Don't forget to also install any additional **php-modules** for PHP 7.3 you've had previously installed
+for e.g. Icinga Web 2 modules.
+
+There's also a new **service** included which replaces the previous one for php-fpm:
+
+Stop the old service: `systemctl stop rh-php71-php-fpm.service`
+Start the new service: `systemctl start rh-php73-php-fpm.service`
+
+You can now safely remove the previous dependency if you like:
+
+`yum remove rh-php71*`
+
+**Discontinued package updates**
+
+Icinga Web 2 v2.8+ is not supported on these platforms:
+
+* RHEL / CentOS 6
+* Debian 8 Jessie
+* Ubuntu 16.04 LTS (Xenial Xerus)
+
+Please consider an upgrade of your central Icinga system to a newer distribution release.
+
+[icinga.com](https://icinga.com/subscription/support-details/) provides an overview about
+currently supported distributions.
+
+**Framework changes affecting third-party code**
+
+* Url parameter `view=compact` is now deprecated. `showCompact` should be used instead.
+ Details are in pull request [#4164](https://github.com/Icinga/icingaweb2/pull/4164).
+* Form elements of type checkbox now need to be checked prior submission if they're
+ required. Previously setting `required => true` didn't cause the browser to complain
+ if such a checkbox wasn't checked. Browsers now do complain if so.
+* The general layout now uses flexbox instead of fixed positioning. This applies to the
+ `#header`, `#sidebar`, `#main`, `#footer`, `#col1`, `#col2` and a column's controls.
+ `#sidebar` and `#main` are now additionally wrapped in a new container `#content-wrapper`.
+
+## Upgrading to Icinga Web 2 2.7.x <a id="upgrading-to-2.7.x"></a>
+
+**Breaking changes**
+
+* We've upgraded jQuery to version 3.4.1. If you're a module developer, please add `?_dev` to your address bar to check
+ for log messages emitted by jquery-migrate. (https://github.com/jquery/jquery-migrate) Your javascript code will still
+ work, though jquery-migrate will notify you if you're utilizing deprecated/removed functions. jquery-migrate will be
+ removed with Icinga Web v2.8 and code not adjusted accordingly will stop working.
+* If you're using a language other than english and you've adjusted or disabled module dashboards, you'll need to
+ update all of your `dashboard.ini` files. A CLI command exists to assist you with this task. Enable the `migrate`
+ module and run the following on the host where these files exist: `icingacli migrate dashboard sections --verbose`
+
+## Upgrading to Icinga Web 2 2.6.x <a id="upgrading-to-2.6.x"></a>
+
+* Icinga Web 2 version 2.6.x does not introduce any backward incompatible change.
+
+## Upgrading to Icinga Web 2 2.5.x <a id="upgrading-to-2.5.x"></a>
+
+> **Attention**
+>
+> Icinga Web 2 v2.5 requires **at least PHP 5.6**.
+
+**Breaking changes**
+
+* Hash marks (`#`) in INI files are no longer recognized as comments by
+ [parse_ini_file](https://secure.php.net/manual/en/function.parse-ini-file.php) since PHP 7.0.
+* Existing sessions of logged-in users do no longer work as expected due to a change in the `User` data structure.
+ Everyone who was logged in before the upgrade has to log out once.
+
+**Changes in packaging and dependencies**
+
+Valid for distributions:

+* RHEL / CentOS 6 + 7
+ * Upgrading to PHP 7.0 / 7.1 via RedHat SCL (new dependency)
+ * See [Upgrading to FPM](02-Installation.md#upgrading-to-fpm) for manual steps that

+* SUSE SLE 12
+ * Upgrading PHP to >= 5.6.0 via the alternative packages.
+ You might have to confirm the replacement of PHP < 5.6 - but that

+ * Make sure to enable the new Apache module `a2enmod php7` and restart `apache2`
+
+**Discontinued package updates**
+
+Icinga Web 2 v2.5+ is not supported on these platforms:
+
+* Debian 7 wheezy
+* Ubuntu 14.04 LTS (trusty)
+* SUSE SLE 11 (all service packs)
+
+Please consider an upgrade of your central Icinga system to a newer distribution release.
+
+[packages.icinga.com](https://packages.icinga.com) provides an overview about currently supported distributions.
+
+**Database schema**
+
+Icinga Web 2 v2.5.0 requires a schema update for the database. The database schema has been adjusted to support
+usernames up to 254 characters. This is necessary to support the new domain-aware authentication feature.
+
+Continue here for [MySQL](80-Upgrading.md#upgrading-mysql-db) and [PostgreSQL](80-Upgrading.md#upgrading-pgsql-db).
+
+## Upgrading to Icinga Web 2 2.4.x <a id="upgrading-to-2.4.x"></a>
+
+* Icinga Web 2 version 2.4.x does not introduce any backward incompatible change.
+
+## Upgrading to Icinga Web 2 2.3.x <a id="upgrading-to-2.3.x"></a>
+
+* Icinga Web 2 version 2.3.x does not introduce any backward incompatible change.
+
+## Upgrading to Icinga Web 2 2.2.0 <a id="upgrading-to-2.2.0"></a>
+
+* The menu entry `Authorization` beneath `Config` has been renamed to `Authentication`. The role, user backend and user
+ group backend configuration which was previously found beneath `Authentication` has been moved to `Application`.
+
+## Upgrading to Icinga Web 2 2.1.x <a id="upgrading-to-2.1.x"></a>
+
+* Since Icinga Web 2 version 2.1.3 LDAP user group backends respect the configuration option `group_filter`.
+ Users who changed the configuration manually and used the option `filter` instead
+ have to change it back to `group_filter`.
+
+## Upgrading to Icinga Web 2 2.0.0 <a id="upgrading-to-2.0.0"></a>
+
+* Icinga Web 2 installations from package on RHEL/CentOS 7 now depend on `php-ZendFramework` which is available through
+ the [EPEL repository](https://fedoraproject.org/wiki/EPEL). Before, Zend was installed as Icinga Web 2 vendor library
+ through the package `icingaweb2-vendor-zend`. After upgrading, please make sure to remove the package
+ `icingaweb2-vendor-zend`.
+
+* Icinga Web 2 version 2.0.0 requires permissions for accessing modules. Those permissions are automatically generated
+ for each installed module in the format `module/<moduleName>`. Administrators have to grant the module permissions to
+ users and/or user groups in the roles configuration for permitting access to specific modules.
+ In addition, restrictions provided by modules are now configurable for each installed module too. Before,
+ a module had to be enabled before having the possibility to configure restrictions.
+
+* The **instances.ini** configuration file provided by the monitoring module
+ has been renamed to **commandtransports.ini**. The content and location of
+ the file remains unchanged.
+
+* The location of a user's preferences has been changed from
+ **&lt;config-dir&gt;/preferences/&lt;username&gt;.ini** to
+ **&lt;config-dir&gt;/preferences/&lt;username&gt;/config.ini**.
+ The content of the file remains unchanged.
+
+## Upgrading to Icinga Web 2 Release Candidate 1 <a id="upgrading-to-rc1"></a>
+
+The first release candidate of Icinga Web 2 introduces the following non-backward compatible changes:
+
+* The database schema has been adjusted and the tables `icingaweb_group` and
+ `icingaweb_group_membership` were altered to ensure referential integrity.
+ Please use the upgrade script located in **etc/schema/** to update your
+ database schema
+
+* Users who are using PostgreSQL < v9.1 are required to upgrade their
+ environment to v9.1+ as this is the new minimum required version
+ for utilizing PostgreSQL as database backend
+
+* The restrictions `monitoring/hosts/filter` and `monitoring/services/filter`
+ provided by the monitoring module were merged together. The new
+ restriction is called `monitoring/filter/objects` and supports only a
+ predefined subset of filter columns. Please see the module's security
+ related documentation for more details.
+
+## Upgrading to Icinga Web 2 Beta 3 <a id="upgrading-to-beta3"></a>
+
+Because Icinga Web 2 Beta 3 does not introduce any backward incompatible change you don't have to change your
+configuration files after upgrading to Icinga Web 2 Beta 3.
+
+## Upgrading to Icinga Web 2 Beta 2 <a id="upgrading-to-beta2"></a>
+
+Icinga Web 2 Beta 2 introduces access control based on roles for secured actions. If you've already set up Icinga Web 2,
+you are required to create the file **roles.ini** beneath Icinga Web 2's configuration directory with the following
+content:
+```
+[administrators]
+users = "your_user_name, another_user_name"
+permissions = "*"
+```
+
+After please log out from Icinga Web 2 and log in again for having all permissions granted.
+
+If you delegated authentication to your web server using the `autologin` backend, you have to switch to the `external`
+authentication backend to be able to log in again. The new name better reflects
+what's going on. A similar change
+affects environments that opted for not storing preferences, your new backend is `none`.
+
+## Upgrading the MySQL Database <a id="upgrading-mysql-db"></a>
+
+If you installed Icinga Web 2 from package, please check the upgrade scripts located in
+**/usr/share/doc/icingaweb2/schema/mysql-upgrades** (Debian/Ubuntu: **/usr/share/icingaweb2/etc/schema/mysql-upgrades**)
+to update your database schema.
+In case you installed Icinga Web 2 from source, please find the upgrade scripts in **etc/schema/mysql-upgrades**.
+
+> **Note**
+>
+> If there isn't an upgrade file for your current version available, there's nothing to do.
+
+Apply all database schema upgrade files incrementally.
+
+```
+# mysql -u root -p icingaweb2 < /usr/share/doc/icingaweb2/schema/mysql-upgrades/<version>.sql
+```
+
+**Example:** You are upgrading Icinga Web 2 from version `2.4.0` to `2.5.0`. Look into
+the `upgrade` directory:
+
+```
+$ ls /usr/share/doc/icingaweb2/schema/mysql-upgrades/
+2.0.0beta3-2.0.0rc1.sql 2.5.0.sql
+```
+
+The upgrade file `2.5.0.sql` must be applied for the v2.5.0 release. If there are multiple
+upgrade files involved, apply them incrementally.
+
+```
+# mysql -u root -p icinga < /usr/share/doc/icingaweb2/schema/mysql-upgrades/2.5.0.sql
+```
+
+## Upgrading the PostgreSQL Database <a id="upgrading-pgsql-db"></a>
+
+If you installed Icinga Web 2 from package, please check the upgrade scripts located in
+**/usr/share/doc/icingaweb2/schema/pgsql-upgrades** (Debian/Ubuntu: **/usr/share/icingaweb2/etc/schema/pgsql-upgrades**)
+to update your database schema.
+In case you installed Icinga Web 2 from source, please find the upgrade scripts in **etc/schema/pgsql-upgrades**.
+
+> **Note**
+>
+> If there isn't an upgrade file for your current version available, there's nothing to do.
+
+Apply all database schema upgrade files incrementally.
+
+```
+# export PGPASSWORD=icingaweb2
+# psql -U icingaweb2 -d icingaweb2 < /usr/share/doc/icingaweb2/schema/pgsql-upgrades/<version>.sql
+```
+
+**Example:** You are upgrading Icinga Web 2 from version `2.4.0` to `2.5.0`. Look into
+the `upgrade` directory:
+
+```
+$ ls /usr/share/doc/icingaweb2/schema/pgsql-upgrades/
+2.0.0beta3-2.0.0rc1.sql 2.5.0.sql
+```
+
+The upgrade file `2.5.0.sql` must be applied for the v2.5.0 release. If there are multiple
+upgrade files involved, apply them incrementally.
+
+```
+# export PGPASSWORD=icingaweb2
+# psql -U icingaweb2 -d icingaweb2 < /usr/share/doc/icingaweb2/schema/pgsql-upgrades/2.5.0.sql

+# SELinux <a id="selinux"></a>
+
+## Introduction <a id="selinux-introduction"></a>
+
+SELinux is a mandatory access control (MAC) system on Linux which adds a fine granular permission system for access
+to all resources on the system such as files, devices, networks and inter-process communication.
+
+The most important questions are answered briefly in the [FAQ of the SELinux Project](https://selinuxproject.org/page/FAQ).
+For more details on SELinux and how to actually use and administrate it on your systems have a look at
+[Red Hat Enterprise Linux 7 - SELinux User's and Administrator's Guide](https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/SELinux_Users_and_Administrators_Guide/index.html).
+For a simplified (and funny) introduction download the [SELinux Coloring Book](https://github.com/mairin/selinux-coloring-book).
+
+
+## Policy <a id="selinux-policy"></a>
+
+Icinga Web 2 is providing its own SELinux policy for RPM-based systems running the targeted policy
+which confines Icinga Web 2 with support for all its modules.
+
+The policy for Icinga Web 2 will also require the policy for Icinga 2 which provides access to its interfaces.
+It covers only the scenario running Icinga Web 2 in Apache HTTP Server with mod_php.
+
+Use your distribution's package manager to install the `icingaweb2-selinux` package.
+
+## General <a id="selinux-policy-general"></a>
+
+When the SELinux policy package for Icinga Web 2 is installed, it creates its own type of apache content and labels its
+configuration `icingaweb2_config_t` to allow confining access to it.
+
+## Types <a id="selinux-policy-types"></a>
+
+The configuration is labeled `icingaweb2_config_t` and other services can request access to it by using the interfaces
+`icingaweb2_read_config` and `icingaweb2_manage_config`.
+Files requiring read access are labeled `icingaweb2_content_t`. Files requiring write access are labeled
+`icingaweb2_rw_content_t`.
+
+## Booleans <a id="selinux-policy-booleans"></a>
+
+SELinux is based on the least level of access required for a service to run. Using booleans you can grant more access in
+a defined way. The Icinga Web 2 policy package provides the following booleans.
+
+**httpd_can_manage_icingaweb2_config**
+
+Having this boolean enabled allows httpd to write to the configuration labeled `icingaweb2_config_t`. This is enabled by
+default. If not needed, you can disable it for more security. But this will disable all web based configuration of
+Icinga Web 2.
+
+### Optional Booleans <a id="selinux-optional-booleans"></a>
+
+The Icinga Web 2 policy package does not enable booleans not required by default. In order to allow these things,
+you'll need to enable them manually. (i.e. with the tool `setsebool`)
+
+**Ldap**
+If you want to allow httpd to connect to the ldap port, you must turn on the `httpd_can_connect_ldap` boolean.
+Disabled by default.
+
+## Bugreports <a id="selinux-bugreports"></a>
+
+If you experience any problems while running SELinux in enforcing mode try to reproduce it in permissive mode. If the
+problem persists, it is not related to SELinux because in permissive mode SELinux will not deny anything.
+
+When filing a bug report please add the following information additionally to the
+[common ones](https://icinga.com/icinga/faq/):
+* Output of `semodule -l | grep -e icinga2 -e icingaweb2 -e nagios -e apache`
+* Output of `semanage boolean -l | grep icinga`
+* Output of `ps -eZ | grep httpd`
+* Output of `audit2allow -li /var/log/audit/audit.log`
+
+If access to a file is blocked and you can tell which one, please provided the output of `ls -lZ /path/to/file` and the
+directory above.
+
+If asked for full audit.log, add `-w /etc/shadow -p w` to `/etc/audit/rules.d/audit.rules` and restart the audit daemon.
+Reproduce the problem and add `/var/log/audit/audit.log` to the bug report. The added audit rule includes
+the path of files where access was denied.
+
+If asked to provide full audit log with dontaudit rules disabled, execute `semodule -DB` before reproducing the problem.
+After that enable the rules again to prevent auditd spamming your logfile by executing `semodule -B`.

+ Organised prehistoric cultures began developing on Bulgarian lands
+ during the Neolithic period. Its ancient history saw the presence
+ of the Thracians and later the Greeks and Romans. The emergence of
+ a unified Bulgarian state dates back to the establishment of the
+ <a href="#">First Bulgarian Empire</a>
+ in 681 CE, which dominated most of the
+ Balkans and functioned as a cultural hub for Slavs during the
+ Middle Ages.
+ </p>
+ <p>
+ With the downfall of the Second Bulgarian Empire in 1396, its
+ <a href="#">territories came under Ottoman</a>
+ rule for nearly five centuries.
+ The Russo-Turkish War (1877–78) led to the formation of the Third
+ Bulgarian State. The following years saw several conflicts with its
+ neighbours, which prompted Bulgaria to align with Germany in both
+ world wars.
+ </p>
+ <p>
+ In 1946 it became a single-party socialist state as part of the
+ Soviet-led Eastern Bloc. In December 1989 the ruling Communist
+ Party allowed multi-party elections, which subsequently led to
+ Bulgaria's transition into a democracy and a market-based economy.

+ The development of Final Fantasy VIII began in 1997, during the
+ English localization process of Final Fantasy VII. It was produced
+ <a href="#">by Shinji Hashimoto</a>,
+ and directed by Yoshinori Kitase. The music
+ was scored by regular series composer Nobuo Uematsu, and in a
+ series first a vocal piece was written as the game's theme, "Eyes
+ on Me", performed by Faye Wong.
+ </p>
+ <p>
+ The game was positively received by
+ critics,
+ <a href="#">who praised the originality </a>
+ and scope of the game. It was
+ voted the 22nd-best game of all time in 2006 by readers of the
+ Japanese magazine Famitsu. The game was a commercial success;
+ thirteen weeks after its release,
