Use your existing LDAP as authentication-backend for your wordpress!

So what are the differences to other WordPress-LDAP-Authentication-Plugins?

  • 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
  • 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.
  • Failsafe: Due to the users being created in WordPress’ User-database they can also log in when the LDAP-backend currently is gone.
  • Role-Aware: You can map WordPress’ roles to values of an existing LDAP-attribute.

For more Information on the configuration have a look at


  1. Upload the extracted folder authLdap to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Configure the Plugin via the ‘authLdap’-Configuration-Page.

Very flexible plugin, stable codebase, excellent documentation. I especially like the clean configuration interface, which enables me to set the LDAP search filters easily. Plus, you don’t really have to do much – the default settings are what you need when authenticating against an openLDAP instance.
