Central Authentication Service

This is community space for the Jasig sponsored CAS efforts.

Introduction - What is CAS?

CAS is an enterprise Single Sign-On solution for web services. Single Sign-On (SSO) means a better user experience when running a multitude of web services, each with its own means of authentication. With a SSO solution, different web services may authenticate to one authorative source of trust, that the user needs to log in to, instead of requiring the end-user to log in into each separate service.

A number of out-of-the-box solutions exist to enable web services written in a specific language, or based on a framework, to use CAS. This would enable deployers to implement a SSO solution in a matter of hours.
