When originally implemented, the TAMU CAS system was designed only to support the College Station campus based employees and students. It is used to authenticate to generally available campus IT services including wireless, Howdy (COMPASS), Library Services, Federated Services and any service that needs to allow student authentication.
Single Sign-on (SSO) was designed to provide authentication to employee services for ALL employees of the Texas A&M University System.
It is agreed the best long term strategic solution remains a single, comprehensive authentication solution.
