Central Authentication Service (CAS)

Yale University developed the Central Authentication Service (CAS) to provide a centralized Single SignOn Verifier for campus Service Providers. The centralized service offered a number of advantages to both Service Providers and Subjects. Service Providers did not have to manage user accounts or maintain Credential Stores and could focus on maintenance and development of their core services while Subjects had fewer Credentials to manage. CAS has been adopted and implemented by a number of universities and is now an Apereo Foundation project.

Technical requirements and information about the Texas A&M CAS implementation are available on the Infrastructure Services website. A description of the CAS service and an illustration of a basic authentication scenario are also available.
