This module transforms your Drupal site into a central authentication system, allowing other applications to use your Drupal user database for single sign-on. It provides the core functionality for a CAS (Central Authentication Service) server.
The CAS Server module turns a Drupal install into the central authentication system. It makes your database the primary location for other systems to use for authentication in a SSO environment.
This stand-alone module is replacing the CAS Server component of the CAS module.
