Central Authentication Service (CAS)
Apereo CAS provide centralized authentication for supported web applications.
It is one of the two standard mechanisms for authentication at NDSU and is used where possible. It is the preferred mechanism for providing authentication for internal NDSU resources, and secondary for external resources after InCommon.
CAS usage by application is by approval, which is easy to receive. To use CAS in your application or your vendor's application please contact the NDSU Help Desk.
