+INSTALLATION
+============
+
+Dependencies
+------------------
+ppm is provided along with OpenLDAP sources. By default, it is available into contrib/slapd-modules.
+ - make sure both OpenLDAP sources and ppm are available for building.
+ - install cracklib development files if you want to test passwords against cracklib
+ - install pandoc if you want to build the man page
+
+
+Build
+-----
+Enter contrib/slapd-modules/ppm directory
+
+You can optionally customize some variables if you don't want the default ones:
+- prefix: prefix of the path where ppm is to be installed (defaults to /usr/local)
+- ldap_subdir: OpenLDAP specific subdirectory for modules and configurations (defaults to openldap )
+- moduledir: where the ppm module is to be deployed (defaults to $prefix/$libexecdir/$ldap_subdir)
+- etcdir: used to compose default sysconfdir location (defaults to $prefix/etc)
+- sysconfdir: where the ppm example policy is to be deployed (defaults to $prefix/$etcdir/$ldap_subdir)
+- LDAP_SRC: path to OpenLDAP source directory
+- Options in OPTS variable:
+ CONFIG_FILE: (DEPRECATED) path to a ppm configuration file (see PPM_READ_FILE in ppm.h)
+ note: ppm configuration now lies into pwdCheckModuleArg password policy attribute
+ provided example file is only helpful as an example or for testing
+ CRACKLIB: if defined, link against cracklib
+ DEBUG: If defined, ppm logs its actions with syslog
+
+
+To build ppm, simply run these commands:
+(based upon the default prefix /usr/local of OpenLDAP)
+
+```
+make clean
+make
+make test
+make doc
+make install
+```
+
+Here is an illustrative example showing how to overload some options:
+
+```
+make clean
+make LDAP_SRC=../../.. prefix=/usr/local libdir=/usr/local/lib
+make test LDAP_SRC=../../..
+make doc prefix=/usr/local
+make install prefix=/usr/local libdir=/usr/local/lib
+```

+# NAME
+
+ppm (Password Policy Module) - extension of the password policy overlay
+
+# SYNOPSIS
+
+ETCDIR/ppm.example
+
+# DESCRIPTION
+
+**ppm** is an OpenLDAP module for checking password quality when they are modified.
+Passwords are checked against the presence or absence of certain character classes.
+
+This module is used as an extension of the OpenLDAP password policy controls,
+see slapo-ppolicy(5) section **pwdCheckModule**.
+
+
+# USAGE
+
+Create a password policy entry and indicate the path of the ppm.so library
+and the content of the desired policy.
+Use a base64 tool to code / decode the content of the policy stored into
+**pwdCheckModuleArg**. Here is an example:
+
+```
+dn: cn=default,ou=policies,dc=my-domain,dc=com
+objectClass: pwdPolicy
+objectClass: top
+objectClass: pwdPolicyChecker
+objectClass: person
+pwdCheckQuality: 2
+pwdAttribute: userPassword
+sn: default
+cn: default
+pwdMinLength: 6
+pwdCheckModule: /usr/local/lib/ppm.so
+pwdCheckModuleArg:: bWluUXVhbGl0eSAzCmNoZWNrUkROIDAKZm9yYmlkZGVuQ2hhcnMKbWF4Q29uc2VjdXRpdmVQZXJDbGFzcyAwCnVzZUNyYWNrbGliIDAKY3JhY2tsaWJEaWN0IC92YXIvY2FjaGUvY3JhY2tsaWIvY3JhY2tsaWJfZGljdApjbGFzcy11cHBlckNhc2UgQUJDREVGR0hJSktMTU5PUFFSU1RVVldYWVogMCAxCmNsYXNzLWxvd2VyQ2FzZSBhYmNkZWZnaGlqa2xtbm9wcXJzdHV2d3h5eiAwIDEKY2xhc3MtZGlnaXQgMDEyMzQ1Njc4OSAwIDEKY2xhc3Mtc3BlY2lhbCA8Piw/Oy46LyHCp8O5JSrCtV7CqCTCo8KyJsOpfiIjJ3soWy18w6hgX1zDp17DoEApXcKwPX0rIDAgMQ==
+```
+
+
+See **slapo-ppolicy** for more information, but to sum up:
+
+- enable ppolicy overlay in your database.
+- define a default password policy in OpenLDAP configuration or use pwdPolicySubentry attribute to point to the given policy.
+
+This example show the activation for a **slapd.conf** file
+(see **slapd-config** and **slapo-ppolicy** for more information for
+ **cn=config** configuration)
+
+```
+overlay ppolicy
+ppolicy_default "cn=default,ou=policies,dc=my-domain,dc=com"
+#ppolicy_use_lockout # for having more infos about the lockout
+```
+
+
+# FEATURES
+
+Here are the main features:
+
+- 4 character classes are defined by default:
+upper case, lower case, digits and special characters.
+
+- more character classes can be defined, just write your own.
+
+- passwords must match the amount of quality points.
+A point is validated when at least m characters of the corresponding
+character class are present in the password.
+
+- passwords must have at least n of the corresponding character class
+present, else they are rejected.
+
+- the two previous criteria are checked against any specific character class
+defined.
+
+- if a password contains any of the forbidden characters, then it is
+rejected.
+
+- if a password contains tokens from the RDN, then it is rejected.
+
+- if a password does not pass cracklib check, then it is rejected.
+
+
+# CONFIGURATION
+
+Since OpenLDAP 2.5 version, ppm configuration is held in a binary
+attribute of the password policy: **pwdCheckModuleArg**
+
+The example file (**ETCDIR/ppm.example** by default) is to be
+considered as an example configuration, to import in the **pwdCheckModuleArg**
+attribute. It is also used for testing passwords with the test program
+provided.
+
+If for some reasons, any parameter is not found, it will be given its
+default value.
+
+Note: you can still compile ppm to use the configuration file, by enabling
+**PPM_READ_FILE** in **ppm.h** (but this is deprecated now). If you decide to do so,
+you can use the **PPM_CONFIG_FILE** environment variable for overloading the
+configuration file path.
+
+The syntax of a configuration line is:
+
+```
+parameter value [min] [minForPoint]
+```
+
+with spaces being delimiters and Line Feed (LF) ending the line.
+
+Parameter names **are** case sensitive.
+
+Lines beginning by a **#** are considered as comments.
+
+The default configuration is the following:
+
+```
+# minQuality parameter
+# Format:
+# minQuality [NUMBER]
+# Description:
+# One point is granted for each class for which MIN_FOR_POINT criteria is fulfilled.
+# defines the minimum point numbers for the password to be accepted.
+minQuality 3
+
+# checkRDN parameter
+# Format:
+# checkRDN [0 | 1]
+# Description:
+# If set to 1, password must not contain a token from the RDN.
+# Tokens are separated by the following delimiters : space tabulation _ - , ; £
+checkRDN 0
+
+# forbiddenChars parameter
+# Format:
+# forbiddenChars [CHARACTERS_FORBIDDEN]
+# Description:
+# Defines the forbidden characters list (no separator).
+# If one of them is found in the password, then it is rejected.
+forbiddenChars
+
+# maxConsecutivePerClass parameter
+# Format:
+# maxConsecutivePerClass [NUMBER]
+# Description:
+# Defines the maximum number of consecutive character allowed for any class
+maxConsecutivePerClass 0
+
+# useCracklib parameter
+# Format:
+# useCracklib [0 | 1]
+# Description:
+# If set to 1, the password must pass the cracklib check
+useCracklib 0
+
+# cracklibDict parameter
+# Format:
+# cracklibDict [path_to_cracklib_dictionary]
+# Description:
+# directory+filename-prefix that your version of CrackLib will go hunting for
+# For example, /var/pw_dict resolves as /var/pw_dict.pwd,
+# /var/pw_dict.pwi and /var/pw_dict.hwm dictionary files
+cracklibDict /var/cache/cracklib/cracklib_dict
+
+# classes parameter
+# Format:
+# class-[CLASS_NAME] [CHARACTERS_DEFINING_CLASS] [MIN] [MIN_FOR_POINT]
+# Description:
+# [CHARACTERS_DEFINING_CLASS]: characters defining the class (no separator)
+# [MIN]: If at least [MIN] characters of this class is not found in the password, then it is rejected
+# [MIN_FOR_POINT]: one point is granted if password contains at least [MIN_FOR_POINT] character numbers of this class
+class-upperCase ABCDEFGHIJKLMNOPQRSTUVWXYZ 0 1
+class-lowerCase abcdefghijklmnopqrstuvwxyz 0 1
+class-digit 0123456789 0 1
+class-special <>,?;.:/!§ù%*µ^¨$£²&é~"#'{([-|è`_\ç^à@)]°=}+ 0 1
+```
+
+# EXAMPLE
+
+With this policy:
+```
+minQuality 4
+forbiddenChars .?,
+checkRDN 1
+class-upperCase ABCDEFGHIJKLMNOPQRSTUVWXYZ 0 5
+class-lowerCase abcdefghijklmnopqrstuvwxyz 0 12
+class-digit 0123456789 0 1
+class-special <>,?;.:/!§ù%*µ^¨$£²&é~"#'{([-|è`_\ç^à@)]°=}+ 0 1
+class-myClass :) 1 1``
+```
+
+the password **ThereIsNoCowLevel)** is working, because:
+
+- it has 4 character classes validated : upper, lower, special, and myClass
+- it has no character among .?,
+- it has at least one character among : or )
+
+but it won't work for the user uid=John Cowlevel,ou=people,cn=example,cn=com,
+because the token "Cowlevel" from his RDN exists in the password (case insensitive).
+
+
+# LOGS
+
+If a user password is rejected by **ppm**, the user will get this type of message:
+
+Typical user message from ldappasswd(5):
+
+```
+ Result: Constraint violation (19)
+ Additional info: Password for dn=\"%s\" does not pass required number of strength checks (2 of 3)
+```
+
+A more detailed message is written to the server log.

+.SH NAME
+.PP
+ppm (Password Policy Module) - extension of the password policy overlay
+.SH SYNOPSIS
+.PP
+ETCDIR/ppm.example
+.SH DESCRIPTION
+.PP
+\f[B]ppm\f[R] is an OpenLDAP module for checking password quality when
+they are modified.
+Passwords are checked against the presence or absence of certain
+character classes.
+.PP
+This module is used as an extension of the OpenLDAP password policy
+controls, see slapo-ppolicy(5) section \f[B]pwdCheckModule\f[R].
+.SH USAGE
+.PP
+Create a password policy entry and indicate the path of the ppm.so
+library and the content of the desired policy.
+Use a base64 tool to code / decode the content of the policy stored into
+\f[B]pwdCheckModuleArg\f[R].
+Here is an example:
+.IP
+.nf
+\f[C]
+dn: cn=default,ou=policies,dc=my-domain,dc=com
+objectClass: pwdPolicy
+objectClass: top
+objectClass: pwdPolicyChecker
+objectClass: person
+pwdCheckQuality: 2
+pwdAttribute: userPassword
+sn: default
+cn: default
+pwdMinLength: 6
+pwdCheckModule: /usr/local/lib/ppm.so
+pwdCheckModuleArg:: bWluUXVhbGl0eSAzCmNoZWNrUkROIDAKZm9yYmlkZGVuQ2hhcnMKbWF4Q29uc2VjdXRpdmVQZXJDbGFzcyAwCnVzZUNyYWNrbGliIDAKY3JhY2tsaWJEaWN0IC92YXIvY2FjaGUvY3JhY2tsaWIvY3JhY2tsaWJfZGljdApjbGFzcy11cHBlckNhc2UgQUJDREVGR0hJSktMTU5PUFFSU1RVVldYWVogMCAxCmNsYXNzLWxvd2VyQ2FzZSBhYmNkZWZnaGlqa2xtbm9wcXJzdHV2d3h5eiAwIDEKY2xhc3MtZGlnaXQgMDEyMzQ1Njc4OSAwIDEKY2xhc3Mtc3BlY2lhbCA8Piw/Oy46LyHCp8O5JSrCtV7CqCTCo8KyJsOpfiIjJ3soWy18w6hgX1zDp17DoEApXcKwPX0rIDAgMQ==

+.PP
+See \f[B]slapo-ppolicy\f[R] for more information, but to sum up:
+.IP \[bu] 2
+enable ppolicy overlay in your database.
+.IP \[bu] 2
+define a default password policy in OpenLDAP configuration or use
+pwdPolicySubentry attribute to point to the given policy.
+.PP
+This example show the activation for a \f[B]slapd.conf\f[R] file (see
+\f[B]slapd-config\f[R] and \f[B]slapo-ppolicy\f[R] for more information
+for \f[B]cn=config\f[R] configuration)

+\f[R]
+.fi
+.SH FEATURES
+.PP
+Here are the main features:
+.IP \[bu] 2
+4 character classes are defined by default: upper case, lower case,
+digits and special characters.
+.IP \[bu] 2
+more character classes can be defined, just write your own.
+.IP \[bu] 2
+passwords must match the amount of quality points.
+A point is validated when at least m characters of the corresponding
+character class are present in the password.
+.IP \[bu] 2
+passwords must have at least n of the corresponding character class
+present, else they are rejected.
+.IP \[bu] 2
+the two previous criteria are checked against any specific character
+class defined.
+.IP \[bu] 2
+if a password contains any of the forbidden characters, then it is
+rejected.
+.IP \[bu] 2
+if a password contains tokens from the RDN, then it is rejected.
+.IP \[bu] 2
+if a password does not pass cracklib check, then it is rejected.
+.SH CONFIGURATION
+.PP
+Since OpenLDAP 2.5 version, ppm configuration is held in a binary
+attribute of the password policy: \f[B]pwdCheckModuleArg\f[R]
+.PP
+The example file (\f[B]ETCDIR/ppm.example\f[R] by default) is to be
+considered as an example configuration, to import in the
+\f[B]pwdCheckModuleArg\f[R] attribute.
+It is also used for testing passwords with the test program provided.
+.PP
+If for some reasons, any parameter is not found, it will be given its
+default value.
+.PP
+Note: you can still compile ppm to use the configuration file, by
+enabling \f[B]PPM_READ_FILE\f[R] in \f[B]ppm.h\f[R] (but this is
+deprecated now).
+If you decide to do so, you can use the \f[B]PPM_CONFIG_FILE\f[R]
+environment variable for overloading the configuration file path.
+.PP
+The syntax of a configuration line is:
+.IP
+.nf
+\f[C]
+parameter value [min] [minForPoint]
+\f[R]
+.fi
+.PP
+with spaces being delimiters and Line Feed (LF) ending the line.
+.PP
