Class and Description
Authenticator An Authenticator is a component (usually a Valve or Container) that provides some sort of authentication service.
Cluster A Cluster works as a Cluster client/server for the local host Different Cluster implementations can be used to support different ways to communicate within the Cluster.

SessionEvent General event for notifying listeners of significant changes on a Session.
SessionListener Interface defining a listener for significant Session generated events.
ThreadBindingListener Callback for establishing naming association when entering the application scope.
