LDAP Authentication 2

Use your existing LDAP as authentication-backend for your wordpress!
So what are the differences to other WordPress-LDAP-Authentication-Plugins?
<ul>
<li>Flexible: You are totaly free in which LDAP-backend to use. Due to the extensive configuration you can freely decide how to do the authentication of your users. It simply depends on your filters</li>
<li>Independent: As soon as a user logs in, it is added/updated to the WordPress’ user-database to allow wordpress to always use the correct data. You only have to administer your users once.</li>
<li>Failsafe: Due to the users being created in WordPress’ User-database they can also log in when the LDAP-backend currently is gone.</li>
<li>Role-Aware: You can map WordPress’ roles to values of an existing LDAP-attribute.</li>
</ul>

This plugin is the only one in WP.org which works out of the box, it's super easy to set up and even has user group mapping included. Thanks once again and totally recommended to every one.
