All Implemented Interfaces:

public class CasProcessingFilterEntryPoint
extends Object
implements AuthenticationEntryPoint, InitializingBean

Used by the SecurityEnforcementFilter to commence authentication via the Yale Central Authentication Service (CAS).

The user's browser will be redirected to the Yale CAS enterprise-wide login page. This page is specified by the loginUrl property. Once login is complete, the CAS login page will redirect to the page indicated by the service property. The service is a HTTP URL belonging to the current application. The service URL is monitored by the CasProcessingFilter, which will validate the CAS login was successful.
