public interface Authenticator

An Authenticator is a component (usually a Valve or Container) that provides some sort of authentication service. The interface itself has no functional significance, but is used as a tagging mechanism so that other components can detect the presence (via an "instanceof Authenticator" test) of an already configured authentication service.
