OpenID Server

The OpenID Server plugin allows other websites to authenticate users who are registered on your site via OpenID.  This can be advantageous if you manage a number of sites and want users to be able to employ a single account on all of them.  For Drupal or phpBB sites running on the same server, you may wish to use the Drupal Login Synchronization or phpBB Login Synchronization plugins instead.

The plugin only provides the ability for users to log into other sites using OpenID;  to allow users to log into your site with OpenID, install the OpenID Login plugin.
