CAS

Central Authentication Service

Le Central Authentication Service (CAS) est un système d'authentification unique (SSO) pour le web développé par Shawn Bayern de l'Université Yale, partenaire majeur dans le développement de uPortal. Ce logiciel est implanté dans plusieurs universités et organismes dans le monde.

The Central Authentication Service (CAS) is a single sign-on protocol for the web.[1] 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.

Enterprise Single Sign-On - CAS provides a friendly open source community that actively supports and contributes to the project. While the project is rooted in higher-ed open source, it has grown to an international audience spanning Fortune 500 companies and small special-purpose installations.
