Class RejectUsersAuthenticationHandler

java.lang.Object
  org.jasig.cas.authentication.handler.support.AbstractPreAndPostProcessingAuthenticationHandler
      org.jasig.cas.authentication.handler.support.AbstractUsernamePasswordAuthenticationHandler
          org.jasig.cas.adaptors.generic.RejectUsersAuthenticationHandler

All Implemented Interfaces:

AuthenticationHandler, NamedAuthenticationHandler

public class RejectUsersAuthenticationHandler
extends AbstractUsernamePasswordAuthenticationHandler

AuthenticationHandler which fails to authenticate a user purporting to be one of the blocked usernames, and blindly authenticates all other users.

Note that RejectUsersAuthenticationHandler throws an exception when the user is found in the map. This is done to indicate that this is an extreme case and any AuthenticationManager checking the RejectUsersAuthenticationHandler should not continue checking other Authentication Handlers on the failure of RejectUsersAuthenticationHandler to authenticate someone.
