Ldap Authentication


I have been tasked with setting up an instance of Omeka. I’m having a hard time getting ldap authentication working. Has anyone successfully implemented ldap authentication? If so what version and how. I have Omeka version 2.5.1 and I tried the plugins

  1. Central Auth
  2. Ldap 0.4.0
  3. Ldap 0.3.0

and another 1 that I disabled and uninstalled. The error I’m getting is “An unexpected failure occurred” which isn’t telling me much. Any advice given is appreciated.


Hello remy730, I’m the maintainer of those plugins, so I hope I can help.

As a first step, I’d recommend checking both the Omeka and PHP error logs. Documentation for Omeka is available here:

LDAP is an extension of PHP so it may not be loaded. If it is loaded, it may be a problem with the LDAP configuration, which varies from server to server.

Hello, thanks for the reply. I went down to version 2.1.4 and the 0.4.0 plugin worked perfectly. Thank you for your reply and the plugin.

Could you point me in the direction of this LDAP extension?

I would like to offer some form of authentication to Omeka if possible. Just wondering what the current options are in Omeka re authentication.



There is the Central Auth plugin which provides authentication via LDAP or CAS:

It is a newer version of LDAP plugin which only supports LDAP:
