org.apache.derby.impl.jdbc.authentication.AuthenticationServiceBase

org.apache.derby.impl.jdbc.authentication.NoneAuthenticationServiceImpl

All Implemented Interfaces:

UserAuthenticator, AuthenticationService, ModuleControl, ModuleSupportable, PropertySetCallback

public final class NoneAuthenticationServiceImpl
extends AuthenticationServiceBase
implements UserAuthenticator

This authentication service does not care much about authentication.

It is a quiescient authentication service that will basically satisfy any authentication request, as JBMS system was not instructed to have any particular authentication scheme to be loaded at boot-up time.
