From Joomla! Authentication Tools (JAuthTools)

[edit] JAuthManager 1.5

JAuthManager 1.5 provides a single point interface for accessing SSO plugins and any service providers they might offer, identity provider plugins, authentication and user plugins.

[edit] JAuthManager 1.6

JAuthManager is a system designed to provide a base UI in Joomla! 1.5 for administering tasks such as group membership mappings and the configuration of JAuthTools related plugins (e.g. SSO and User Source plugins).

A secondary aim is to provide diagnostic tools so that administrators can determine problems with their setup.

JAuthManager is primarily aimed at supporting the User Sources related systems and providing a friendlier interface for building group maps.
