The goal of this authentication plug-in is to make sure that each user in Moodle only has one active session simultaneously. Once the user logs in, the existing previous session is terminated. Note that this does not work with SingleSignOn plugins.

To work properly, the plugin needs to be on top of the authentication plugins list and Database-stored sessions are enabled. Check the module documentation to more information.

Administrator can configure whether teacher and administrator roles are affected by the plugin.

This plugin is being maintained by ED-ROM, the portuguese Moodle Partner.
