-Add configuration entries to config.php. These entries are:
+add "addPlugin('ldap', array('setting'=>'value', 'setting2'=>'value2', ...);" to the bottom of your config.php
 
-The following are documented at http://pear.php.net/manual/en/package.networking.net-ldap2.connecting.php
-$config['ldap']['binddn']
-$config['ldap']['bindpw']
-$config['ldap']['basedn']
-$config['ldap']['host']
 
-$config['ldap']['nickname_attribute'] Set this to the name of the ldap attribute that holds the username. For example, on Microsoft's Active Directory, this should be set to 'sAMAccountName'
-$config['ldap']['nickname_email'] Set this to the name of the ldap attribute that holds the user's email address. For example, on Microsoft's Active Directory, this should be set to 'mail'

-$config['ldap']['nickname_homepage'] Set this to the name of the ldap attribute that holds the the url of the user's home page.
-$config['ldap']['nickname_location'] Set this to the name of the ldap attribute that holds the user's location.
 
-$config['ldap']['authoritative'] Set to true if LDAP's responses are authoritative (meaning if LDAP fails, do check the any other plugins or the internal password database)
+Settings
-$config['ldap']['autoregister'] Set to true if users should be automatically created when they attempt to login
+========
+authn_authoritative:  Set to true if LDAP's responses are authoritative (meaning if LDAP fails, do check the any other plugins or the internal password database).
+autoregistration: Set to true if users should be automatically created when they attempt to login.
 
-Finally, add "addPlugin('ldap');" to the bottom of your config.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
 
+attributes: an array with the key being the StatusNet user attribute name, and the value the LDAP attribute name
+    nickname*
+    email
+    fullname
+    homepage
+    location
+    
+* required
+
+Example
+=======
+Here's an example of an LDAP plugin configuration that connects to Microsoft Active Directory.
+
+addPlugin('ldap', array(
+    'binddn'=>'username',
+    'bindpw'=>'password',
+    'basedn'=>'OU=Users,OU=StatusNet,OU=US,DC=americas,DC=global,DC=loc',

+You can get a significant boost in performance using Sphinx Search
+instead of your database server to search for users and notices.
+<http://sphinxsearch.com/>.
+
+Configuration
+-------------
+
+In StatusNet's configuration, you can adjust the following settings
+under 'sphinx':
+
+enabled: Set to true to enable. Default false.
+server: a string with the hostname of the sphinx server.
+port: an integer with the port number of the sphinx server.
+
+
+Requirements
+------------
+
+To use a Sphinx server to search users and notices, you also need
+to install, compile and enable the sphinx pecl extension for php on the
+client side, which itself depends on the sphinx development files.
+"pecl install sphinx" should take care of that. Add "extension=sphinx.so"
+to your php.ini and reload apache to enable it.
+
+You can update your MySQL or Postgresql databases to drop their fulltext
+search indexes, since they're now provided by sphinx.
+
+
+You will also need a Sphinx server to serve the search queries.
+
+On the sphinx server side, a script reads the main database and build
+the keyword index. A cron job reads the database and keeps the sphinx
+indexes up to date. scripts/sphinx-cron.sh should be called by cron
+every 5 minutes, for example. scripts/sphinx.sh is an init.d script
+to start and stop the sphinx search daemon.
+
+
+Server configuration
+--------------------
+scripts/gen_config.php can generate a sphinx.conf file listing MySQL
+data sources for your databases. You may need to tweak paths afterwards.
+
+  $ plugins/SphinxSearch/scripts/gen_config.php > sphinx.conf
+
+If you wish, you can build a full config yourself based on sphinx.conf.sample
