Central Authentication System (CAS) is a single signon service provided by some universities. Read about it here.

phpCAS is a client for the CAS service. You can read about that here. You have to download it separately and point this script to it.

This plugin uses some hooks in WordPress's authentication system to bypass the normal login screen and authenticate over CAS instead. Note that logged-in state is still maintained in cookies, and user entries are created in the local database.
