(CAS) is a single sign-on protocol for the web. Its purpose is to permit a user to access multiple applications while providing their credentials (such as userid and password) only once. It also allows web applications to authenticate users without gaining access to a user's security credentials, such as a password. The name CAS also refers to a software package that implements this protocol.

CAS is a single sign-on facility; once a user authenticates to CAS, the user need not continue to supply a password to access other applications that use CAS.
UserIds and Passwords are handled only by centrally maintained servers making this solution ideal for authenticating applications hosted offsite. CAS also has the ability to provide high level role information and biographical attributes about the authenticated user that may be used for authorization purposes.
No costs are charged for this service.
