public interface: Authenticator [javadoc | source]

All Known Implementing Classes:
    BasicAuthenticator, SSLAuthenticator, FormAuthenticator, DigestAuthenticator, NonLoginAuthenticator, AuthenticatorBase

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.
