The only change + is that the `correct_escapes` configuration has been removed, and + is not the default. + +Security +-------- + +A number of configuration items have moved into the "security" +subsection of radiusd.conf. If you use these, you should move them. +Otherwise, they can be ignored. + +The list of moved options is:: + + chroot + user + group + allow_core_dumps + reject_delay + status_server + +These entries should be moved from "radiusd.conf" to the "security" +subsection of that file. + +Naming +------ + +Many names used by configuration items were inconsistent in earlier +versions of the server. These names have been unified in version 3. + +If a file is being referenced or created the config item ``filename`` +is used. + +If a file is being created, the initial permissions are set by the +``permissions`` config item. + +If a directory hierarchy needs to be created, the permissions are set +by ``dir_permissions``. + +If an external host is referenced in the context of a module the +``server`` config item is used. + +Unless the config item is a well recognised portmanteau +(as ``filename`` is for example), it must be written as multiple +distinct words separated by underscores ``_``. + +The configuration items ``file``, ``script_file``, ``module``, +``detail``, ``detailfile``, ``attrsfile``, ``perm``, ``dirperm``, +``detailperm``, and ``hostname`` are deprecated. As well as any false +portmanteaus, and configuration items that used hyphens as word +delimiters. e.g. ``foo-bar`` has been changed to ``foo_bar``. Please +update your module configuration to use the new syntax. + +In most cases the server will tell you the replacement config item to +use. As always, run the server in debugging mode to see these +messages. + +Modules Directory +----------------- + +As of version 3, the ``modules/`` directory no longer exists. + +Instead, all "example" modules have been put into the +``mods-available/`` directory. Modules which can be loaded by the +server are placed in the ``mods-enabled/`` directory. All of the +modules in that directory will be loaded. This means that the +``instantiate`` section of radiusd.conf is less important. The only +reason to list a module in the ``instantiate`` section is to force +ordering when the modules are loaded. + +Modules can be enabled by creating a soft link. For module ``foo``, do:: + + $ cd raddb/mods-enabled + $ ln -s ../mods-available/foo + +To create "local" versions of the modules, we suggest copying the file +instead. This leaves the original file (with documentation) in the +``mods-available/`` directory. Local changes should go into the +``mods-enabled/`` directory. + +Module-specific configuration files are now in the ``mods-config/`` +directory. This change allows for better organization, and means that +there are fewer files in the main ``raddb`` directory. See +``mods-config/README.rst`` for more details. + +Changed Modules +--------------- + +The following modules have been changed. + + +rlm_sql +~~~~~~~ + +The SQL configuration has been moved from ``sql.conf`` to +``mods-available/sql``. The ``sqlippool.conf`` file has also been +moved to ``mods-available/sqlippool``. + +The SQL module configuration has been changed. The old connection +pool options are no longer accepted:: + + num_sql_socks + connect_failure_retry_delay + lifetime + max_queries + +Instead, a connection pool configuration is used. This configuration +contains all of the functionality of the previous configuration, but +in a more generic form. It also is used in multiple modules, meaning +that there are fewer different configuration items. The mapping +between the configuration items is:: + + num_sql_socks -> pool { max } + connect_failure_retry_delay -> pool { retry_delay } + lifetime -> pool { lifetime } + max_queries -> pool { uses } + +The pool configuration adds a number of new configuration options, +which allow the administrator to better control how FreeRADIUS uses +SQL connection pools. + +The following parameters have been changed:: + + trace -> removed + tracefile -> logfile + +The logfile is intended to log SQL queries performed. If you need to +debug the server, use debugging mode. If ``logfile`` is set, then +*all* SQL queries will go to ``logfile``. + +You can now use a NULL SQL database:: + + driver = rlm_sql_null + +This is an empty driver which will always return "success". It is +intended to be used to replace the ``sql_log`` module, and to work in +conjunction with the ``radsqlrelay`` program. Simply take your normal +configuration for raddb/mods-enabled/sql, and set:: + + driver = rlm_sql_null + ... + logfile = ${radacctdir}/sql.log + +All of the SQL queries will be logged to that file. The connection +pool does not need to be configured for the ``null`` SQL driver. It +can be left as-is, or deleted from the SQL configuration file. + +rlm_sql_sybase +~~~~~~~~~~~~~~ + +The ``rlm_sql_sybase`` module has been renamed to ``rlm_sql_freetds`` +and the old ``rlm_sql_freetds`` module has been removed. + +``rlm_sql_sybase`` used the newer ct-lib API, and ``rlm_sql_freetds`` +used an older API and was incomplete. + +The new ``rlm_sql_freetds`` module now also supports database +selection on connection startup so ``use`` statements no longer +have to be included in queries. + +sql/dialup.conf +~~~~~~~~~~~~~~~ + +Queries for post-auth and accounting calls have been re-arranged. The +SQL module will now expand the 'reference' configuration item in the +appropriate sub-section, and resolve this to a configuration +item. This behaviour is similar to rlm_linelog. This dynamic +expansion allows for a dynamic mapping between accounting types and +SQL queries. Previously, the mapping was fixed. Any "new" accounting +type was ignored by the module. Now, support for any accounting type +can be added by just adding a new target, as below. + +Queries from v2 may be manually copied to the new v3 +``dialup.conf`` file (``raddb/mods-config/sql/main/<dialect>/queries.conf``). +When doing this you may also need to update references to the +accounting tables, as their definitions will now be outside of +the subsection containing the query. + +The mapping from old "fixed" query to new "dynamic" query is as follows:: + + accounting_onoff_query -> accounting.type.accounting-on.query + accounting_update_query -> accounting.type.interim-update.query + accounting_update_query_alt +> accounting.type.interim-update.query + accounting_start_query -> accounting.type.start.query + accounting_start_query_alt +> accounting.type.start.query + accounting_stop_query -> accounting.type.stop.query + accounting_stop_query_alt +> accounting.type.stop.query + postauth_query -> post-auth.query + +Alternatively a v2 config may be patched to work with the +v3 module by adding the following:: + + accounting { + reference = "%{tolower:type.%{Acct-Status-Type}.query}" + type { + accounting-on { + query = "${....accounting_onoff_query}" + } + accounting-off { + query = "${....accounting_onoff_query}" + } + start { + query = "${....accounting_start_query}" + query = "${....accounting_start_query_alt}" + } + interim-update { + query = "${....accounting_update_query}" + query = "${....accounting_update_query_alt}" + } + stop { + query = "${....accounting_stop_query}" + query = "${....accounting_stop_query_alt}" + } + } + } + + post-auth { + query = "${..postauth_query}" + } + +In general, it is safer to migrate the configuration rather than +trying to "patch" it, to make it look like a v2 configuration. + +Note that the sub-sections holding the queries are labelled +``accounting-on``, and not ``accounting_on``. The reason is that the +names of these sections are taken directly from the +``Accounting-Request`` packet, and the ``Acct-Status-Type`` field. +The ``sql`` module looks at the value of that field, and then looks +for a section of that name, in order to find the query to use. + +That process means that the server can be extended to support any new +value of ``Acct-Status-Type``, simply by adding a named sub-section, +and a query. This behavior is preferable to that of v2, which had +hard-coded queries for certain ``Acct-Status-Type`` values, and was +ignored all other values. + +rlm_ldap +~~~~~~~~ + +The LDAP module configuration has been substantially changed. Please +read ``raddb/mods-available/ldap``. It now uses a connection pool, +just like the SQL module. + +Many of the configuration items remain the same, but they have been +moved into subsections. This change is largely cosmetic, but it makes +the configuration clearer. Instead of having a large set of random +configuration items, they are now organized into logical groups. + +You will need to read your old LDAP configuration, and migrate it +manually to the new configuration. Simply copying the old +configuration WILL NOT WORK. + +Users upgrading from v2 who used to call the ldap module in +``post-auth`` should now set ``edir_autz = yes``, and remove the ``ldap`` +module from the ``post-auth`` section. + +rlm_ldap and LDAP-Group +~~~~~~~~~~~~~~~~~~~~~~~ + +In v2 the registration of the ``LDAP-Group`` pair comparison was done +by the last instance of rlm_ldap to be instantiated. In v3 this has +changed so that only the default ``ldap {}`` instance registers +``LDAP-Group``. + +If ``<instance>-LDAP-Group`` is already used throughout your configuration +no changes will be needed. + +rlm_ldap authentication +~~~~~~~~~~~~~~~~~~~~~~~ + +In v2 the LDAP module had a ``set_auth_type`` configuration item, +which forced ``Auth-Type := ldap``. This was removed in 3.x.x as it +often did not work, and was not consistent with the rest of the +server. We generally recommend that LDAP should be used as a +database, and that FreeRADIUS should do authentication. + +The only reason to use ``Auth-Type := ldap`` is when the LDAP server +will not supply the "known good" password to FreeRADIUS, *and* where +the Access-Request contains User-Password. This situation happens +only for Active Directory. If you think you need to force ``Auth-Type +:= ldap`` in other situations, you are very likely to be wrong. + +The following is an example of what should be inserted into the +``authorize {}`` and ``authenticate {}`` sections of the relevant +virtual-servers, to get functionality equivalent to v2.x:: + + authorize { + ... + ldap + if ((ok || updated) && User-Password) { + update control { + Auth-Type := ldap + } + } + ... + } + + authenticate { + ... + Auth-Type ldap { + ldap + } + ... + } + +rlm_eap +~~~~~~~ + +The EAP configuration has been moved from ``eap.conf`` to +``mods-available/eap``. A new ``pwd`` subsection has been added for +EAP-PWD. + +rlm_expiration & rlm_logintime +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The rlm_expiration and rlm_logintime modules no longer add a ``Reply-Message``, +the same behaviour can be achieved checking the return code of the module and +adding the ``Reply-Message`` with unlang:: + + expiration + if (userlock) { + update reply { + Reply-Message := "Your account has expired" + } + } + +rlm_unix +~~~~~~~~ + +The ``unix`` module does not have an ``authenticate`` section. So you +cannot set ``Auth-Type := System``. The ``unix`` module has also been +deleted from the examples in ``sites-available/``. Listing it there +has been deprecated for many years. + +The PAP module can do crypt authentication. It should be used instead +of Unix authentication. + +The Unix module still can pull the passwords from ``/etc/passwd``, or +``/etc/shadow``. This is done by listing it in the ``authorize`` +section, as is done in the examples in ``sites-available/``. However, +some systems using NIS or NSS will not supply passwords to the +``unix`` module. For those systems, we recommend putting users and +passwords into a database, instead of relying on ``/etc/passwd``. + +rlm_preprocess +~~~~~~~~~~~~~~ + +In v2 ``huntroups`` and ``users`` files were loaded from default locations +without being configured explicitly. Since 3.x.x you need to set +``huntgroups`` and ``users`` configuration item(s) in module section in order +to get them being processed. + +New Modules +----------- + +rlm_date +~~~~~~~~ + +Instances of rlm_date register an xlat method which can translate +integer and date values to an arbitrarily formatted date time +string, or an arbitrarily formated time string to an integer, +depending on the attribute type passed. + +rlm_rest +~~~~~~~~ + +The ``rest`` module is used to translate RADIUS requests into +RESTfull HTTP requests. Currently supported body types are JSON +and POST. + +rlm_unpack +~~~~~~~~~~ + +The ``unpack`` module is used to turn data buried inside of binary +attributes. e.g. if we have ``Class = 0x00000001020304`` then:: + + Tmp-Integer-0 := "%{unpack:&Class 4 short}" + +will unpack octets 4 and 5 as a "short", which has value 0x0304. +All integers are assumed to be in network byte order. + +rlm_yubikey +~~~~~~~~~~~ + +The ``yubikey`` module can be used to forward yubikey OTP token +values to a Yubico validation server, or decrypt the token +using a PSK. + +Deleted Modules +--------------- + +The following modules have been deleted, and are no longer supported +in Version 3. If you are using one of these modules, your +configuration can probably be changed to not need it. Otherwise email +the freeradius-devel list, and ask about the module. + +rlm_acct_unique +~~~~~~~~~~~~~~~ + +This module has been replaced by the "acct_unique" policy. See +raddb/policy.d/accounting. + +The method for calculating the value of acct_unique has changed. +However, as this method was configurable, this change should not +matter. The only issue is in having a v2 and v3 server writing to the +same database at the same time. They will calculate different values +for Acct-Unique-Id. + +rlm_acctlog +~~~~~~~~~~~ + +You should use rlm_linelog instead. That module has a superset of the +acctlog functionality. + +rlm_attr_rewrite +~~~~~~~~~~~~~~~~ + +The attr_rewrite module looked for an attribute, and then re-wrote it, +or created a new attribute. All of that can be done in "unlang". + +A sample configuration in "unlang" is:: + + if (request:Calling-Station-Id) { + update request { + Calling-Station-Id := "...." + } + } + +We suggest updating all uses of attr_rewrite to use unlang instead. + +rlm_checkval +~~~~~~~~~~~~ + +The checkval module compared two attributes. All of that can be done in "unlang":: + + if (&request:Calling-Station-Id == &control:Calling-Station-Id) { + ok + } + +We suggest updating all uses of checkval to use unlang instead. + +rlm_dbm +~~~~~~~ + +No one seems to use it. There is no sample configuration for it. +There is no speed advantage to using it over the "files" module. +Modern systems are fast enough that 10K entries can be read from the +"users" file in about 10ms. If you need more users than that, use a +real database such as SQL. + +rlm_fastusers +~~~~~~~~~~~~~ + +No one seems to use it. It has been deprecated since Version 2.0.0. +The "files" module was rewritten so that the "fastusers" module was no +longer necessary. + +rlm_policy +~~~~~~~~~~ + +No one seems to use it. Almost all of its functionality is available +via "unlang". + +rlm_sim_files +~~~~~~~~~~~~~ + +The rlm_sim_files module has been deleted. It was never marked "stable", +and was never used in a production environment. There are better ways +to test EAP. + +If you want similar functionality, see rlm_passwd. It can read CSV +files, and create attributes from them. + +rlm_sql_log +~~~~~~~~~~~ + +This has been replaced with the "null" sql driver. See +raddb/mods-available/sql for an example configuration. + +The main SQL module has more functionality than rlm_sql_log, and +results in less code in the server. + +Other Functionality +------------------- + +The following is a list of new / changed functionality. + +RadSec +~~~~~~ + +RadSec (or RADIUS over TLS) is now supported. RADIUS over bare TCP +is also supported, but is recommended only for secure networks. + +See ``sites-available/tls`` for complete details on using TLS. The server +can both receive incoming TLS connections, and also originate outgoing +TLS connections. + +The TLS configuration is taken from the old EAP-TLS configuration. It +is largely identical to the old EAP-TLS configuration, so it should be +simple to use and configure. It re-uses much of the EAP-TLS code, +so it is well-tested and reliable. + +Once RadSec is enabled, normal debugging mode will not work. This is +because the TLS code requires threading to work properly. Instead of doing:: + + $ radiusd -X + +you will need to do:: + + $ radiusd -fxx -l stdout + +That's the price to pay for using RadSec. This limitation may be +lifted in a future version of the server. + + +PAP and User-Password +~~~~~~~~~~~~~~~~~~~~~ + +From version 3 onwards the server no longer supports authenticating +against a cleartext password in the 'User-Password' attribute. Any +occurences of this (for instance, in the users file) should now be changed +to 'Cleartext-Password' instead. + +e.g. change entries like this:: + + bob User-Password == "hello" + +to ones like this:: + + bob Cleartext-Password := "hello" + + +If this is not done, authentication will likely fail. The server will +also print a helpful message in debugging mode. + +If it really is impossible to do this, the following unlang inserted above +the call to the pap module may be used to copy User-Password to the correct +attribute:: + + if (!control:Cleartext-Password && control:User-Password) { + update control { + Cleartext-Password := "%{control:User-Password}" + } + } + +However, this should only be seen as a temporary, not permanent, fix. +It is better to fix your databases to use the correct configuration. + +Unlang +~~~~~~ + +The unlang policy language is compatible with v2, but has a number of +new features. See ``man unlang`` for complete documentation. + +ERRORS + +Many more errors are caught when the server is starting up. Syntax +errors in ``unlang`` are caught, and a helpful error message is +printed. The error message points to the exact place where the error +occurred:: + + ./raddb/sites-enabled/default[230]: Parse error in condition + ERROR: if (User-Name ! "bob") { + ERROR: ^ Invalid operator + +``update`` sections are more generic. Instead of doing ``update +reply``, you can do the following:: + + update { + reply:Class := 0x0000 + control:Cleartext-Password := "hello" + } + +This change means that you need fewer ``update`` sections. + +COMPARISONS + +Attribute comparisons can be done via the ``&`` operator. When you +needed to compare two attributes, the old comparison style was:: + + if (User-Name == "%{control:Tmp-String-0}") { + +This syntax is inefficient, as the ``Tmp-String-0`` attribute would be +printed to an intermediate string, causing unnecessary work. You can +now instead compare the two attributes directly:: + + if (&User-Name == &control:Tmp-String-0) { + +See ``man unlang`` for more details. + +CASTS + +Casts are now permitted. This allows you to force type-specific +comparisons:: + + if (<ipaddr>"%{sql: SELECT...}" == 127.0.0.1) { + +This forces the string returned by the SELECT to be treated as an IP +address, and compare to ``127.0.0.1``. Previously, the comparison +would have been done as a simple string comparison. + +NETWORKS + +IP networks are now supported:: + + if (127.0.0.1/32 == 127.0.0.1) { + +Will be ``true``. The various comparison operators can be used to +check IP network membership:: + + if (127/8 > 127.0.0.1) { + +Returns ``true``, because ``127.0.0.1`` is within the ``127/8`` +network. However, the following comparison will return ``false``:: + + if (127/8 > 192.168.0.1) { + +because ``192.168.0.1`` is outside of the ``127/8`` network. + +OPTIMIZATION + +As ``unlang`` is now pre-compiled, many compile-time optimizations are +done. This means that the debug output may not be exactly the same as +what is in the configuration files:: + + if (0 && (User-Name == "bob')) { + +The result will always be ``false``, as the ``if 0`` prevents the +following ``&& ...`` from being evaluated. + +Not only that, but the entire contents of that section will be ignored +entirely:: + + if (0) { + this_module_does_not_exist + and_this_one_does_not_exist_either + } + +In v2, that configuration would result in a parse error, as there is +no module called ``this_module_does_not_exist``. In v3, that text is +ignored. This ability allows you to have dynamic configurations where +certain parts are used (or not) depending on compile-time configuration. + +Similarly, conditions which always evaluate to ``true`` will be +optimized away:: + + if (1) { + files + } + +That configuration will never show the ``if (1)`` output in debugging mode. + + +Dialup_admin +------------ + +The dialup_admin directory has been removed. No one stepped forward +to maintain it, and the code had not been changed in many years. + diff --git a/raddb/all.mk b/raddb/all.mk new file mode 100644 index 0000000..a7f4f14 --- /dev/null +++ b/raddb/all.mk @@ -0,0 +1,152 @@ +# +# The list of files to install. +# +LOCAL_FILES := clients.conf dictionary templates.conf experimental.conf \ + proxy.conf radiusd.conf trigger.conf README.rst panic.gdb + +DEFAULT_SITES := default inner-tunnel +LOCAL_SITES := $(addprefix raddb/sites-enabled/,$(DEFAULT_SITES)) + +DEFAULT_MODULES := always attr_filter chap date \ + detail detail.log digest dynamic_clients eap \ + echo exec expiration expr files linelog logintime \ + mschap ntlm_auth pap passwd preprocess radutmp realm \ + replicate soh sradutmp totp unix unpack utf8 + +LOCAL_MODULES := $(addprefix raddb/mods-enabled/,$(DEFAULT_MODULES)) + +LOCAL_CERT_FILES := Makefile README.md xpextensions \ + ca.cnf server.cnf inner-server.cnf \ + client.cnf bootstrap + +# +# We don't create the installed certs if we're building a package, +# OR if OpenSSL is not available. +# +ifeq "$(PACKAGE)" "" +ifneq "$(OPENSSL_LIBS)" "" +LOCAL_CERT_PRODUCTS := $(addprefix $(R)$(raddbdir)/certs/,ca.key ca.pem \ + client.key client.pem server.key server.pem) +endif +endif + +LEGACY_LINKS := $(addprefix $(R)$(raddbdir)/,users huntgroups hints) + +RADDB_DIRS := certs mods-available mods-enabled policy.d \ + sites-available sites-enabled \ + $(patsubst raddb/%,%,$(shell find raddb/mods-config -type d -print)) + +# Installed directories +INSTALL_RADDB_DIRS := $(R)$(raddbdir)/ $(addprefix $(R)$(raddbdir)/, $(RADDB_DIRS)) + +# Grab files from the various subdirectories +INSTALL_FILES := $(wildcard raddb/sites-available/* raddb/mods-available/*) \ + $(addprefix raddb/,$(LOCAL_FILES)) \ + $(addprefix raddb/certs/,$(LOCAL_CERT_FILES)) \ + $(shell find raddb/mods-config -type f -print) \ + $(shell find raddb/policy.d -type f -print) + +# Re-write local files to installed files, filtering out editor backups +INSTALL_RADDB := $(patsubst raddb/%,$(R)$(raddbdir)/%,\ + $(filter-out %~,$(INSTALL_FILES))) + +all: build.raddb + +build.raddb: $(LOCAL_SITES) $(LOCAL_MODULES) + +clean: clean.raddb + +install: install.raddb + +# Local build rules +raddb/sites-enabled raddb/mods-enabled: + @echo INSTALL $@ + @$(INSTALL) -d -m 750 $@ + +# Set up the default modules for running in-source builds +raddb/mods-enabled/%: raddb/mods-available/% | raddb/mods-enabled + @echo "LN-S $@" + @cd $(dir $@) && ln -sf ../mods-available/$(notdir $@) + +# Set up the default sites for running in-source builds +raddb/sites-enabled/%: raddb/sites-available/% | raddb/sites-enabled + @echo "LN-S $@" + @cd $(dir $@) && ln -sf ../sites-available/$(notdir $@) + +# Installation rules for directories.

To +make a set of default (i.e. test) certificates, simply type: + +``` +$ ./bootstrap +``` + +The `openssl` command will be run against the sample configuration +files included here, and will make a self-signed certificate authority +(i.e. root CA), and a server certificate. This "root CA" should be +installed on any client machine needing to do EAP-TLS, PEAP, or +EAP-TTLS. + +The Extended Key Usage (EKU) fields for "TLS web server" will be +automatically included in the server certificate. Without those +extensions many clients will refuse to authenticate to FreeRADIUS. + +The root CA and the "XP Extensions" file also contain a +crlDistributionPoints attribute. Many systems need this to be present +in order to validate the RADIUS server certificate. The RADIUS server +must have the URI defined but the CA need not have...however it is +best practice for a CA to have a revocation URI. Note that whilst the +Windows Mobile client cannot actually use the CRL when doing 802.1X it +is recommended that the URI be an actual working URL and contain a +revocation format file as there may be other OS behaviour at play and +future OSes that may do something with that URI. + +For Windows, you will need to import the `p12` and/or the `der` format +of the certificates. Linux systems need the `pem` format. + +In general, you should use self-signed certificates for 802.1X (EAP) +authentication. When you list root CAs from other organisations in +the `ca_file`, you permit them to masquerade as you, to authenticate +your users, and to issue client certificates for EAP-TLS. + +If you already have CA and server certificates, rename (or delete) +this directory, and create a new `certs` directory containing your +certificates. Note that the `make install` command will **not** +over-write your existing `raddb/certs` directory. + + +## New Installations of FreeRADIUS + +We suggest that new installations use the test certificates for +initial tests, and then create real certificates to use for normal +user authentication. See the instructions below for how to create the +various certificates. The old test certificates can be deleted by +running the following command: + +``` +$ make destroycerts +``` + +Then, follow the instructions below for creating real certificates. + +If you do not want to enable EAP-TLS, PEAP, or EAP-TTLS, then delete +the relevant sub-sections from the `raddb/mods-available/eap` file. +See the comments in that file for more information. + + +## Making a root Certificate + +We recommend using a private certificate authority (CA). While it can +be difficult to install this CA on multiple client machines, it is (in +general) more secure. + +``` +$ vi ca.cnf +``` + +Edit `default_days` to set the desired lifetime of the CA certificate. + +Edit the `input_password` and `output_password` fields to be the +password for the CA certificate. + +Edit the `[certificate_authority]` section to have the correct values +for your country, state, etc. + +Create the CA certificate: + +``` +$ make ca.pem +``` + +Then the `DER` format needed by Windows: + +``` +$ make ca.der +``` + + +## Making a Server Certificate + +The following steps will let you create a server certificate for use +with TLS-based EAP methods, such as EAP-TLS, PEAP, and TTLS. Follow +similar steps to create an `inner-server.pem` file, for use with +EAP-TLS that is tunneled inside of another TLS-based EAP method. + +``` +$ vi server.cnf +``` + +Edit `default_days` to set the lifetime of the server certificate. +The maximum for this is 825 for compatibility with all client devices. + +Edit the `input_password` and `output_password` fields to be the +password for the server certificate. + +Edit the `[server]` section to have the correct values for your +country, state, etc. Be sure that the `commonName` field here is +different from the `commonName` for the CA certificate. + +Create the server certificate: + +``` +$ make server +``` + + +### Making a certificate for a public CA + +If you wish to use an existing certificate authority, you can +create a certificate signing request for the server certificate, edit +`server.cnf` as above, and run the following command. + +``` +$ make server.csr +``` + +This step creates a "Certificate Signing Request" suitable for +submission to a public CA. + + +## Making a Client certificate + +Client certificates are used by EAP-TLS, and optionally by EAP-TTLS +and PEAP. The following steps outline how to create a client +certificate that is signed by the CA certificate created above. You +will have to have the password for the CA certificate in the +`input_password` and `output_password` fields of the `ca.cnf` file. + +``` +$ vi client.cnf +``` + +Edit `default_days` to set the lifetime of the client certificate. + +Edit the `input_password` and `output_password` fields to be the +password for the client certificate. You will have to give these +passwords to the end user who will be using the certificates. + +Edit the `[client]` section to have the correct values for your +country, state, etc. Be sure that the `commonName` field here is +the `User-Name` which will be used for logins! + +``` +$ make client +``` + +The users certificate will be in `emailAddress.pem`, +e.g. `user@example.com.pem`. + +To create another client certificate, just repeat the steps for +making a client certificate, being sure to enter a different login +name for `commonName`, and a different password. + + +## Performance + +EAP performance for EAP-TLS, TTLS, and PEAP is dominated by SSL +calculations. That is, a normal system can handle PAP +authentication at a rate of 10k packets/s. However, SSL involves +RSA calculations, which are very expensive. To benchmark your system, +do: + +``` +$ openssl speed rsa +``` + +or + +``` +$ openssl speed rsa2048 +``` + +to test 2048 bit keys. + +The number that is printed is the **maximum** number of +authentications per second which can be done for EAP-TLS (or TTLS, +or PEAP). In practice, you will see results much lower than this +number, i.e. the actual EAP-TLS performance may be half of the +number printed here. + +The reason is that EAP requires many round-trip packets, whereas +`openssl speed rsa2028` only does RSA calculations, and nothing else. + + +## Compatibility + +The certificates created using this method are known to be compatible +with ALL operating systems. Some common issues are: + +* iOS and macOS have requirements on certificates. See: + https://support.apple.com/en-us/HT210176 + +* Many systems require certain OIDs in the certificates + (`id-kp-serverAuth` for `TLS Web server authentication`). + If the certificate does not contain these fields, the system + will stop doing EAP. The most visible effect is that the client + starts EAP, gets a few Access-Challenge packets, and then a little + while later re-starts EAP. If this happens, see the FAQ, and the + comments in `raddb/mods-available/eap` for how to fix it. + +* All systems requires the root certificates to be on the client PC. + If it doesn't have them, you will see the same issue as above. + +* Windows XP post SP2 has a bug where it has problems with + certificate chains. i.e. if the server certificate is an + intermediate one, and not a root one, then authentication + will silently fail, as above. + +* Some versions of Windows CE cannot handle 4K RSA certificates. + They will (again) silently fail, as above. + +* In none of these cases will Windows give the end user any + reasonable error message describing what went wrong. This leads + people to blame the RADIUS server. That blame is misplaced. + +* Certificate chains of more than 64K bytes are known to not work. + This is partly a problem in FreeRADIUS. However, most clients cannot + handle 64K certificate chains. Most Access Points will shut down the + EAP session after about 50 round trips, while 64K certificate chains + will take about 60 round trips. So don't use large certificate + chains. They will only work after everyone upgrades everything in the + network. + +* All other operating systems are known to work with EAP and + FreeRADIUS. This includes Linux, the BSDs, macOS, iOS, Android, + Solaris, Symbian, along with all known embedded systems, phones, + WiFi devices, etc. + + +## Security Considerations + +The default certificate configuration files uses SHA256 for message +digests for security. diff --git a/raddb/certs/bootstrap b/raddb/certs/bootstrap new file mode 100755 index 0000000..57de8cf --- /dev/null +++ b/raddb/certs/bootstrap @@ -0,0 +1,86 @@ +#!/bin/sh +# +# This is a wrapper script to create default certificates when the +# server first starts in debugging mode.

Previous +versions of the server required that the administrator configure +multiple EAP modules, one for each certificate being used. + +The selection can be performed in one of two ways. First, the +certificates can be loaded dynamically at run-time. Second, the +certificates can be pre-loaded for speed. + +## Dynamic Loading of Certificate Chains + +The server can dynamically load a certificate chain by setting a +special attribute. This has to be done _after_ the server has +received the EAP identity request, and _before_ the TLS session setup +has started. + +The simplest way to do this is via the following `unlang` statements: + +``` +authenticate { + ... + Auth-Type eap { + if ("%{unpack:&EAP-Message 4 byte}" == 1) { + update control { + TLS-Session-Cert-File := "${certdir}/realms/%{Realm}" + } + } + + eap + } + ... +} +``` + +This configuration looks at the `EAP-Message` attribute, and checks if +it is an EAP-Identity packet. If so, it then adds a special attribute +`TLS-Session-Cert-File`, with a value based on the `Realm`, from the +`User-Name`. That setting tells the server to look in the file for a +certificate. + +If the file is there, and contains a correctly formatted `PEM` +certificate chain, then it is loaded and used. + +If the file does not exist, or the file does not contain a correctly +formatted `PEM` certificate chain, then the user is rejected. + +### Format + +This file should contain the server certificate, followed by +intermediate certificates, in order. i.e. If we have a server +certificate signed by CA1, which is signed by CA2, which is signed by +a root CA, then the "certificate_file" should contain server.pem, +followed by CA1.pem, followed by CA2.pem. + +When using `ca_file` or `ca_dir`, the file should contain only the +server certificate. + +### Private Key + +The private should be placed in the same file as the other +certificates, but at the start. + +``` +private key +server cert +... +ca cert +``` + +The private key can also be placed into a separate file. The filename +should be placed into the `TLS-Session-Cert-Private-Key-File` +attribute. + +For simplicity, the private keys _should not_ have passwords. There +is essentially no security benefit to "securing" the key with a +password, and then placing the password into the file system, right +next to the private key. + +### Realms + +There is no need to place the certificates into files named for each +realm. However, it is by far and away the easiest way to manage these +certificate chains. + +For every realm which is handles this way, the `proxy.conf` file +should define a _local_ realm. That is, it should contain a +definition such as: + +``` +example.org { +} +``` + +This defines the realm `example.org`, and tells FreeRADIUS that there +are no home servers associated with the realm. + +The `suffix` module should also be configured, as per the default +configuration. i.e. list `suffix` in the `authorize` section _before_ +the `eap` module. + +### Caveats + +The root CA certificate for the server certificate should be located +in the `ca_dir`, along with other root CAs. If the root CA is not +there, then it *must* be included at the end of the file. + +These certificates will be loaded and parsed _for every matching +authentication request_. That limitation means that dynamic loading +of the certificates is likely be slow, and to severely impact +performance. The good news is that we can fix that with a little more +configuration. + +## Preloading Certificate Chains + +The server can also pre-load certificate chains. In the EAP module, +you can do: + +``` +eap { + ... + tls { + ... + realm_dir = ${certdir}/realms/ + ... + } + ... +} +``` + +Each file in that directory should be a `PEM` encoded certificate +chain, as described in the previous section. For safety, every file +*must* have a `.pem` as the filename extension. +e.g. `example.org.pem`. + +If there is a corresponding private key, it should be placed into a +`.key` file. e.g. `example.org.key`. + +These certificates will be loaded when the server starts, and cached +for the lifetime of the server. There is no way to reload these +certificates dynamically, the server must be restarted. + +Once the `realm_dir` configuration has been added, the selection of +certificates is identical to that described in the previous section. +Just set `TLS-Session-Cert-File`, and the server will figure it out. + +However, it is possible to dynamically add new certificate, and have +the server pick it up. In fact, as the process for choosing +certificates are the same, the server will do this automatically! + +## RadSec + +The above configuration applies to RadSec, too, as the `tls` +configuration in the server is for all TLS functionality, and not just +EAP. + +This means that the server can accept RadSec connections, and then +present different server certificates to different clients. + +For this functionality to work, the certificates for EAP and RadSec +*should* be in separate directories. + +### Clients + +RadSec clients can set the SNI to send in the `tls` subsection of the +`home_server` definition. Look for "SNI" in `sites-available/tls`, +and see the `hostname` configuration item for documentation. + +For example, an identity provider could host multiple sites, but +present itself with one public IP address. If the RadSec clients do +not use SNI, then they must be configured with the certificate of the +identity provider. + +When SNI is used, the RadSec clients can be configured with the +certificate of the hosted system that they're connecting to. This +ability means that there is no need to change certificates when +changing providers. In addition, there is no need to change the +configuration of all RadSec clients when the hosting system changes +its certifiates. Because the hosting system certificates are never +used. + +Instead, each hosted company is responsible for its own certificates, +and for its own RadSec clients. + +SNI also permits the use of a load balancer such as haproxy. That +load balancer can terminate the TLS connection, and then use SNI to +route the underlying RADIUS TCP traffic to a particular host. + +### Servers + +See the `realm_dir` configuration item in the `tls` subsection for the +location of the server certificates. + +If the server receives an SNI for a realm it does not recognize, it +will just use the default TLS configuration. + +If the realm is recognized (i.e. there is a file in +`${realm_dir}/%{TLS-Server-Name-Indication}.pem`, then that certificate will be chosen, and +present to the RadSec client. If there is no such file, then the +default TLS configuration is used. + +The current behavior is to _require_ that the server certificate is in +a file which taken from +`${realm_dir}/%{TLS-Server-Name-Indication}.pem`. Only the +`realm_dir` portion of the filename is configurable. The SNI portion +is taken from the TLS messages, and the `.pem` suffix is hard-coded in +the source code. + +Taking the filename from an untrusted source is fine here. The +standard (RFC 6066 Section 3) says that the Server Name Indication +field is a DNS "A label". Which means that there are a limited number +of characters allowed: + +* `.`, `-`, `a-Z`, `A-Z`, `0-9` + +If the SNI contain anything else, the TLS connection is rejected. + +Note that if session resumption is enabled for RadSec, the session +cache *must* also cache the `TLS-Server-Name-Indication` attribute. +The SNI is sent on resumption for TLS 1.2 and earlier, but it is not +sent for TLS 1.3. As such, the only way to select the right policy on +resumption is to check the value of the cached +TLS-Server-Name-Indication attribute. + diff --git a/raddb/certs/server.cnf b/raddb/certs/server.cnf new file mode 100644 index 0000000..daca18d --- /dev/null +++ b/raddb/certs/server.cnf @@ -0,0 +1,72 @@ +[ ca ] +default_ca = CA_default + +[ CA_default ] +dir = ./ +certs = $dir +crl_dir = $dir/crl +database = $dir/index.txt +new_certs_dir = $dir +certificate = $dir/server.pem +serial = $dir/serial +crl = $dir/crl.pem +private_key = $dir/server.key +RANDFILE = $dir/.rand +name_opt = ca_default +cert_opt = ca_default +default_days = 60 +default_crl_days = 30 +default_md = sha256 +preserve = no +policy = policy_match +copy_extensions = copy + +[ policy_match ] +countryName = match +stateOrProvinceName = match +organizationName = match +organizationalUnitName = optional +commonName = supplied +emailAddress = optional + +[ policy_anything ] +countryName = optional +stateOrProvinceName = optional +localityName = optional +organizationName = optional +organizationalUnitName = optional +commonName = supplied +emailAddress = optional + +[ req ] +prompt = no +distinguished_name = server +default_bits = 2048 +input_password = whatever +output_password = whatever +#req_extensions = v3_req + +[server] +countryName = FR +stateOrProvinceName = Radius +localityName = Somewhere +organizationName = Example Inc. +emailAddress = admin@example.org +commonName = "Example Server Certificate" + +[ v3_req ] +basicConstraints = CA:FALSE +keyUsage = nonRepudiation, digitalSignature, keyEncipherment +subjectAltName = @alt_names +subjectKeyIdentifier = hash +authorityKeyIdentifier = keyid:always,issuer:always + +# This should be a host name of the RADIUS server. +# Note that the host name is exchanged in EAP *before* +# the user machine has network access.

This practice follows that used by other +servers such as Nginx, Apache, etc. The "modules" directory should +not be used. + +Modules are enabled by creating a file in the mods-enabled/ directory. +You can also create a soft-link from one directory to another:: + + $ cd raddb/mods-enabled + $ ln -s ../mods-available/foo + +This will enable module "foo". Be sure that you have configured the +module correctly before enabling it, otherwise the server will not +start. You can verify the server configuration by running +"radiusd -XC". + +A large number of modules are enabled by default. This allows the +server to work with the largest number of authentication protocols. +Please be careful when disabling modules. You will likely need to +edit the "sites-enabled/" files to remove references to any disabled +modules. + +Conditional Modules +------------------- + +Version 3 allows modules to be conditionally loaded. This is useful +when you want to have a virtual server which references a module, but +does not require it. Instead of editing the virtual server file, you +can just conditionally enable the module. + +Modules are conditionally enabled by adding a "-" before their name in +a virtual server. For example, you can do:: + + server { + authorize { + ... + ldap + -sql + ... + } + } + +This says "require the LDAP module, but use the SQL module only if it +is configured." + +This feature is not very useful for production configurations. It is, +however, very useful for the default examples that ship with the +server. + +Ignoring module +--------------- + +If you see this message:: + + Ignoring module (see raddb/mods-available/README.rst) + +Then you are in the right place. Most of the time this message can be +ignored. The message can be fixed by finding the references to "-module" +in the virtual server, and deleting them. + +Another way to fix it is to configure the module, as described above. + +Simplification +-------------- + +Allowing conditional modules simplifies the default virtual servers +that are shipped with FreeRADIUS. This means that if you want to +enable LDAP (for example), you no longer need to edit the files in +raddb/sites-available/ in order to enable it. + +Instead, you should edit the raddb/mods-available/ldap file to point +to your local LDAP server. Then, enable the module via the soft-link +method described above. + +Once the module is enabled, it will automatically be used in the +default configuration. + +Multiple Instances +------------------ + +It is sometimes necessary to have the same module do two different +things. The server supports this functionality via "instances" of +modules. + +Normally, a module configuration looks like this: + + sql { + ... sql stuff ... + } + +This module is then refereed to as the "sql" module. + + +But what happens if you want to connect to two different SQL +databases? The solution is simple; copy the "sql" module +configuration, and add an instance name after the "sql" string: + + sql mysql1 { + ... configuration for connecting to mysql11 ... + } + + sql mysql2 { + ... configuration for connecting to mysql12 ... + } + +This configuration says "load the SQL module, but create two copies of +it, with different configurations". The different configurations can +be referred to by name, as "mysql1" and "mysql2". That is, anywhere +you would normally use "sql", you could use either "mysql1" or +"mysql2". + +For further examples of using module instances, see the "attr_filter" +module configuration in this directory. diff --git a/raddb/mods-available/abfab_psk_sql b/raddb/mods-available/abfab_psk_sql new file mode 100644 index 0000000..d75130d --- /dev/null +++ b/raddb/mods-available/abfab_psk_sql @@ -0,0 +1,15 @@ +# -*- text -*- +## +## Module for PSK authorizations from ABFAB trust router +## +## $Id$ + +sql psksql { + + driver = "rlm_sql_sqlite" + + sqlite { + filename = "/var/lib/trust_router/keys" + } + +} diff --git a/raddb/mods-available/always b/raddb/mods-available/always new file mode 100644 index 0000000..b77d00c --- /dev/null +++ b/raddb/mods-available/always @@ -0,0 +1,81 @@ +# -*- text -*- +# +# $Id$ + +# +# The "always" module is here for debugging purposes, or +# for use in complex policies. +# Instance simply returns the same result, always, without +# doing anything. +# +# rcode may be one of the following values: +# - reject - Reject the user. +# - fail - Simulate or indicate a failure. +# - ok - Simulate or indicate a success. +# - handled - Indicate that the request has been handled, +# stop processing, and send response if set. +# - invalid - Indicate that the request is invalid. +# - userlock - Indicate that the user account has been +# locked out. +# - notfound - Indicate that a user account can't be found. +# - noop - Simulate a no-op. +# - updated - Indicate that the request has been updated. +# +# If an instance is listed in a session {} section, +# this simulates a user having <integer> sessions. +# +# simulcount = <integer> +# +# If an instance is listed in a session {} section, +# this simulates the user having multilink +# sessions. +# +# mpp = <integer> +# +# An xlat based on the instance name can be called to change the status +# returned by the instance, in this example "always db_status { ... }" +# +# Force the module status to be alive or dead: +# +# %{db_status:alive} +# %{db_status:dead} +# +# Update the rcode returned by an alive module (a dead module returns fail): +# +# %{db_status:ok} +# %{db_status:fail} +# %{db_status:notfound} +# ... +# +# The above xlats expand to the current status of the module.

Instead of +# specifying "authhost" and "accthost" in a realm section, the home +# servers are specified separately in a "home_server" section. For +# backwards compatibility, you can still use the "authhost" and +# "accthost" directives. If you only have one home server for a +# realm, it is easier to use the old-style configuration. +# +# However, if you have multiple servers for a realm, we STRONGLY +# suggest moving to the new-style configuration. +# +# +# Load-balancing and failover between home servers is handled via +# a "home_server_pool" section. +# +# Finally, The "realm" section defines the realm, some options, and +# indicates which server pool should be used for the realm. +# +# This change means that simple configurations now require multiple +# sections to define a realm. However, complex configurations +# are much simpler than before, as multiple realms can share the same +# server pool. +# +# That is, realms point to server pools, and server pools point to +# home servers. Multiple realms can point to one server pool. One +# server pool can point to multiple home servers. Each home server +# can appear in one or more pools. +# +# See sites-available/tls for an example of configuring home servers, +# pools, and realms with TLS. +# + +###################################################################### +# +# This section defines a "Home Server" which is another RADIUS +# server that gets sent proxied requests. In earlier versions +# of FreeRADIUS, home servers were defined in "realm" sections, +# which was awkward. In 2.0, they have been made independent +# from realms, which is better for a number of reasons. +# +# You can proxy to a specific home server by doing: +# +# update control { +# Home-Server-Name = "name of home server" +# } +# +home_server localhost { + # + # Home servers can be sent Access-Request packets + # or Accounting-Request packets. + # + # Allowed values are: + # auth - Handles Access-Request packets + # acct - Handles Accounting-Request packets + # auth+acct - Handles Access-Request packets at "port", + # and Accounting-Request packets at "port + 1" + # coa - Handles CoA-Request and Disconnect-Request packets. + # See also raddb/sites-available/originate-coa + type = auth + + # + # Configure ONE OF the following entries: + # + # IPv4 address + # + ipaddr = 127.0.0.1 + + # OR IPv6 address + # ipv6addr = ::1 + + # OR virtual server + # virtual_server = foo + + # Note that while both ipaddr and ipv6addr will accept + # both addresses and host names, we do NOT recommend + # using host names. When you specify a host name, the + # server has to do a DNS lookup to find the IP address + # of the home server. If the DNS server is slow or + # unresponsive, it means that FreeRADIUS will NOT be + # able to determine the address, and will therefore NOT + # start. + # + # Also, the mapping of host name to address is done ONCE + # when the server starts. If DNS is later updated to + # change the address, FreeRADIUS will NOT discover that + # until after a re-start, or a HUP. + # + # If you specify a virtual_server here, then requests + # will be proxied internally to that virtual server. + # These requests CANNOT be proxied again, however. The + # intent is to have the local server handle packets + # when all home servers are dead. + # + # Requests proxied to a virtual server will be passed + # through the pre-proxy and post-proxy sections, just + # like any other request.

Requests will + # be proxied to a zombie server ONLY when there are no + # live servers. + # + # Any request that is proxied to a home server will continue + # to be sent to that home server until the home server is + # marked dead. At that point, it will fail over to another + # server, if a live server is available. If none is available, + # then the "post-proxy-type fail" handler will be called. + # + # If "status_check" below is something other than "none", then + # the server will start sending status checks at the start of + # the zombie period.

Others may not have a "test" user + # configured that can be used to query the server, to see if + # it is alive. For those servers, we have NO WAY of knowing + # when it becomes alive again. Therefore, after the server + # has been marked dead, we wait a period of time, and mark + # it alive again, in the hope that it has come back to + # life. + # + # If it has NOT come back to life, then FreeRADIUS will wait + # for "zombie_period" before marking it dead again. During + # the "zombie_period", ALL AUTHENTICATIONS WILL FAIL, because + # the home server is still dead.

Virtual Servers. + + FreeRADIUS supports virtual servers. The virtual servers do NOT have +to be set up with the "sites-available" and "sites-enabled" +directories. You can still have one "radiusd.conf" file, and put the +server configuration there: + + ... + server { + authorize { + ... + } + authenticate { + ... + } + ... + } + ... + + The power of virtual servers lies in their ability to separate +policies. A policy can be placed into a virtual server, where it is +guaranteed to affect only the requests that are passed through that +virtual server. In 1.x, the policies were global, and it sometimes +took much effort to write a policy so that it only applied in certain +limited situations. + + +2. What do we mean by "virtual server"? + + + A virtual server is a (nearly complete) RADIUS server, just like a +configuration for FreeRADIUS 1.x. However, FreeRADIUS can now run +multiple virtual servers at the same time. The virtual servers can +even proxy requests to each other! + + The simplest way to create a virtual server is to take the all of +the request processing sections from radius.conf, ("authorize" , +"authenticate", etc.) and wrap them in a "server {}" block, as above. + + You can create another virtual server by: + + 1) defining a new "server foo {...}" section in radiusd.conf + 2) Putting the normal "authorize", etc. sections inside of it + 3) Adding a "listen" section *inside* of the "server" section. + + e.g. + + ... + server foo { + listen { + ipaddr = 127.0.0.1 + port = 2000 + type = auth + } + + authorize { + update control { + Cleartext-Password := "bob" + } + pap + } + + authenticate { + pap + } + } + ... + + With that text added to "radiusd.conf", run the server in debugging +mode (radiusd -X), and in another terminal window, type: + +$ radtest bob bob localhost:2000 0 testing123 + + You should see the server return an Access-Accept. + + +3. Capabilities and limitations + + + The only sub-sections that can appear in a virtual server section +are: + + listen + client + authorize + authenticate + post-auth + pre-proxy + post-proxy + preacct + accounting + session + + All other configuration parameters (modules, etc.) are global. + + Inside of a virtual server, the authorize, etc. sections have their +normal meaning, and can contain anything that an authorize section +could contain in 1.x. + + When a "listen" section is inside of a virtual server definition, it +means that all requests sent to that IP/port will be processed through +the virtual server. There cannot be two "listen" sections with the +same IP address and port number. + + When a "client" section is inside of a virtual server definition, it +means that that client is known only to the "listen" sections that are +also inside of that virtual server. Not only is this client +definition available only to this virtual server, but the details of +the client configuration is also available only to this virtual +server. + + i.e. Two virtual servers can listen on different IP address and +ports, but both can have a client with IP address 127.0.0.1. The +shared secret for that client can be different for each virtual +server. + + +4. More complex "listen" capabilities + + The "listen" sections have a few additional configuration items that +were not in 1.x, and were not mentioned above. These configuration +items enable almost any mapping of IP / port to clients to virtual +servers. + + The configuration items are: + + virtual_server = <name> + + If set, all requests sent to this IP / port are processed + through the named virtual server. + + This directive can be used only for "listen" sections + that are global. i.e. It CANNOT be used if the + "listen" section is inside of a virtual server. + + clients = <name> + + If set, the "listen" section looks for a "clients" section: + + clients <name> { + ... + } + + It looks inside of that named "clients" section for + "client" subsections, at least one of which must + exist. Each client in that section is added to the + list of known clients for this IP / port. No other + clients are known. + + If it is set, it over-rides the list of clients (if + any) in the same virtual server. Note that the + clients are NOT additive! + + If it is not set, then the clients from the current + virtual server (if any) are used. If there are no + clients in this virtual server, then the global + clients are used. + + i.e. The most specific directive is used: + * configuration in this "listen" section + * clients in the same virtual server + * global clients + + The directives are also *exclusive*, not *additive*. + If you have one client in a virtual server, and + another client referenced from a "listen" section, + then that "listen" section will ONLY use the second + client. It will NOT use both clients. + + +5. More complex "client" capabilities + + The "client" sections have a few additional configuration items that +were not in 1.x, and were not mentioned above. These configuration +items enable almost any mapping of IP / port to clients to virtual +servers. + + The configuration items are: + + virtual_server = <name> + + If set, all requests from this client are processed + through the named virtual server. + + This directive can be used only for "client" sections + that are global. i.e. It CANNOT be used if the + "client" section is inside of a virtual server. + + If the "listen" section has a "server" entry, and a matching +client is found ALSO with a "server" entry, then the clients server is +used for that request. + + +6. Worked examples + + + Listening on one socket, and mapping requests from two clients to +two different servers. + + listen { + ... + } + client one { + ... + virtual_server = server_one + } + client two { + ... + virtual_server = server_two + } + server server_one { + authorize { + ... + } + ... + } + server server_two { + authorize { + ... + } + ... + } + + This could also be done as: + + + listen { + ... + virtual_server = server_one + } + client one { + ... + } + client two { + ... + virtual_server = server_two + } + server server_one { + authorize { + ... + } + ... + } + server server_two { + authorize { + ... + } + ... + } + + In this case, the default server for the socket is "server_one", so +there is no need to set that in the client "one" configuration. The +"server_two" configuration for client "two" over-rides the default +setting for the socket. + + Note that the following configuration will NOT work: + + listen { + ... + virtual_server = server_one + } + client one { + ... + } + server server_one { + authorize { + ... + } + ... + } + server server_two { + client two { + ... + } + authorize { + ... + } + ... + } + + In this example, client "two" is hidden inside of the virtual +server, where the "listen" section cannot find it. + + +7. Outlined examples + + This section outlines a number of examples, with alternatives. + + One server, multiple sockets + - multiple "listen" sections in a "server" section + + one server per client + - define multiple servers + - have a global "listen" section + - have multiple global "clients", each with "virtual_server = X" + + two servers, each with their own sockets + - define multiple servers + - put "client" sections into each "server" + - put a "listen" section into each "server" + + Each server can list the same client IP, and the secret + can be different + + two sockets, sharing a list of clients, but pointing to different servers + - define global "listen" sections + - in each, set "virtual_server = X" + - in each, set "clients = Y" + - define "clients Y" section, containing multiple clients. + + This also means that you can have a third socket, which + doesn't share any of these clients. + + +8. How to decide what to do + + + If you want *completely* separate policies for a socket or a client, +then create a separate virtual server. Then, map the request to that +server by setting configuration entries in a "listen" section or in a +"client" section. + + Start off with the common cases first. If most of the clients +and/or sockets get a particular policy, make that policy the default. +Configure it without paying attention to the sockets or clients you +want to add later, and without adding a second virtual server. Once +it works, then add the second virtual server. + + If you want to re-use the previously defined sockets with the second +virtual server, then you will need one or more global "client" +sections. Those clients will contain a "virtual_server = ..." entry +that will direct requests from those clients to the appropriate +virtual server. diff --git a/raddb/sites-available/abfab-tls b/raddb/sites-available/abfab-tls new file mode 100644 index 0000000..b8d0626 --- /dev/null +++ b/raddb/sites-available/abfab-tls @@ -0,0 +1,118 @@ +# +# Example configuration for ABFAB listening on TLS. +# +# $Id$ +# +listen { + ipaddr = * + port = 2083 + type = auth + proto = tcp + + tls { + tls_min_version = "1.2" + private_key_password = whatever + + # Moonshot tends to distribute certs separate from keys + private_key_file = ${certdir}/server.key + certificate_file = ${certdir}/server.pem + ca_file = ${cadir}/ca.pem + dh_file = ${certdir}/dh + fragment_size = 8192 + ca_path = ${cadir} + cipher_list = "DEFAULT" + cache { + enable = no + lifetime = 24 # hours + name = "abfab-tls" + # persist_dir = ${logdir}/abfab-tls + } + require_client_cert = yes + verify { + } + + psk_query = "%{psksql:select hex(key) from psk_keys where keyid = '%{TLS-PSK-Identity}'}" + } + + virtual_server = abfab-idp + clients = radsec-abfab +} + +# There needs to be a separated "listen" section for IPv6. +# Typically it will be identical to the IPv4 one above, but there might be +# some differences (e.g. if a different certificate or port is desired) +listen { + ipaddr = :: + port = 2083 + type = auth + proto = tcp + + tls { + tls_min_version = "1.2" + private_key_password = whatever + + # Moonshot tends to distribute certs separate from keys + private_key_file = ${certdir}/server.key + certificate_file = ${certdir}/server.pem + ca_file = ${cadir}/ca.pem + dh_file = ${certdir}/dh + fragment_size = 8192 + ca_path = ${cadir} + cipher_list = "DEFAULT" + cache { + enable = no + lifetime = 24 # hours + name = "abfab-tls" + # persist_dir = ${logdir}/abfab-tls + } + require_client_cert = yes + verify { + } + + psk_query = "%{psksql:select hex(key) from psk_keys where keyid = '%{TLS-PSK-Identity}'}" + } + + virtual_server = abfab-idp + clients = radsec-abfab +} + +clients radsec-abfab { + # + # Allow all clients, but require TLS. + # This client stanza will match other RP proxies from other + # realms established via the trustrouter.
