What is CAS Technically?
CAS is an Enterprise Java solution to web application authentication that also provides the benefit of Single Sign On (SSO). Technically, SSO can be achieved because the authentication can be removed from the web application and handled centrally. And, when this authentication is handled by a single service, access to many services can be granted once and "remembered" for the life of the web session or even longer though not recommended. Remember too that the SSO feature does not have to be employed and yet CAS authentication still provides a quality authentication mechanism.
