Welcome to the home of the Central Authentication Service project, more commonly referred to as CAS. CAS is an enterprise multilingual single sign-on solution for the web and attempts to be a comprehensive platform for your authentication and authorization needs.
CAS is an open and well-documented authentication protocol. The primary implementation of the protocol is an open-source Java server component by the same name hosted here, with support for a plethora of additional authentication protocols and features such a SAML2, OpenID Connect and many many more.
