Class ChainingAuthenticationComponentImpl

java.lang.Object

org.alfresco.repo.security.authentication.AbstractAuthenticationComponent

org.alfresco.repo.security.authentication.AbstractChainingAuthenticationComponent

org.alfresco.repo.security.authentication.ChainingAuthenticationComponentImpl

All Implemented Interfaces:

AuthenticationComponent, AuthenticationContext, NLTMAuthenticator

public class ChainingAuthenticationComponentImpl
extends AbstractChainingAuthenticationComponent
implements NLTMAuthenticator

A chaining authentication component is required for all the beans that wire up an authentication component and not an authentication service. It supports chaining in much the same way and wires up components in the same way as the chaining authentication service wires up services.
