+The LDAP Authorization plugin allows for StatusNet to handle authorization
+through LDAP.
+
+Installation
+============
+add "addPlugin('ldapAuthorization',
+ array('setting'=>'value', 'setting2'=>'value2', ...);"
+to the bottom of your config.php
+
+You *cannot* use this plugin without the LDAP Authentication plugin
+
+Settings
+========
+provider_name*: name of the LDAP authentication provider that this plugin works with.
+authoritative (false): should this plugin be authoritative for
+ authorization?
+uniqueMember_attribute ('uniqueMember')*: the attribute of a group
+ that lists the DNs of its members
+roles_to_groups*: array that maps StatusNet roles to LDAP groups
+ some StatusNet roles are: moderator, administrator, sandboxed, silenced
+
+The below settings must be exact copies of the settings used for the
+ corresponding LDAP Authentication plugin.
+
+host*: LDAP server name to connect to. You can provide several hosts in an
+ array in which case the hosts are tried from left to right.
+ See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+port: Port on the server.
+ See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+version: LDAP version.
+ See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+starttls: TLS is started after connecting.
+ See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+binddn: The distinguished name to bind as (username).
+ See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+bindpw: Password for the binddn.
+ See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+basedn*: LDAP base name (root directory).
+ See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+options: See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+filter: Default search filter.
+ See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+scope: Default search scope.
+ See http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
+
+* required
+default values are in (parenthesis)
+
+Example
+=======
+Here's an example of an LDAP plugin configuration that connects to
+ Microsoft Active Directory.
+
+addPlugin('ldapAuthentication', array(
+ 'provider_name'=>'Example',
+ 'authoritative'=>true,
+ 'autoregistration'=>true,
+ 'binddn'=>'username',
+ 'bindpw'=>'password',
+ 'basedn'=>'OU=Users,OU=StatusNet,OU=US,DC=americas,DC=global,DC=loc',
+ 'host'=>array('server1', 'server2'),
+ 'password_encoding'=>'ad',
+ 'attributes'=>array(
+ 'username'=>'sAMAccountName',
+ 'nickname'=>'sAMAccountName',
+ 'email'=>'mail',
+ 'fullname'=>'displayName',
+ 'password'=>'unicodePwd')
+));
+addPlugin('ldapAuthorization', array(
+ 'provider_name'=>'Example',
+ 'authoritative'=>false,
+ 'uniqueMember_attribute'=>'uniqueMember',
+ 'roles_to_groups'=> array(
+ 'moderator'=>'CN=SN-Moderators,OU=Users,OU=StatusNet,OU=US,DC=americas,DC=global,DC=loc',
+ 'administrator'=> array('CN=System-Adminstrators,OU=Users,OU=StatusNet,OU=US,DC=americas,DC=global,DC=loc',
+ 'CN=SN-Administrators,OU=Users,OU=StatusNet,OU=US,DC=americas,DC=global,DC=loc')
+ ),
+ 'binddn'=>'username',
+ 'bindpw'=>'password',
+ 'basedn'=>'OU=Users,OU=StatusNet,OU=US,DC=americas,DC=global,DC=loc',
+ 'host'=>array('server1', 'server2')
