What is Central Authentication Service (CAS)?
From Wikipedia (Central Authentication Service):
The Central Authentication Service (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.
Georgia Tech implements the CAS service to allow campus members to easily log into campus websites using their GT Account Username and associated password. However, for a website to utilize CAS, it must be set up correctly, which usually means adding a module, plugin, or library, and configuring it to work with Georgia Tech's CAS servers.
