public class AuthTag
extends javax.servlet.jsp.tagext.TagSupport

Authentication tag for use with the Yale Central Authentication Service.

Typical usage involves placing the tag at the top of the page. The tag checks to determine if the attribute referenced by id/scope exists; if it does, the tag has no runtime effect. If the attribute does not exist, however, a CAS authentication is necessary: if no ticket is present, we redirect to CAS, and if a ticket is present, we validate it. Upon successful CAS authentication (either by a pre-existing attribute or through CAS directly), we store the NetID in the attribute referenced by id/scope.
