If a Windows NT login module were to be used from JAAS, an AuthrityGranter implementation could be created to map a NT Group Principal to a ROLE_USER role for instance.
This AuthenticationProvider is capable of validating org.acegisecurity.providers.UsernamePasswordAuthenticationToken requests contain the correct username and password.
AuthenticationProvider
This implementation is backed by a JAAS configuration.
This LoginModule provides opposite functionality to the JaasAuthenticationProvider API, and should not really be used in conjunction with it.
The JaasAuthenticationProvider allows Acegi to authenticate against Jaas.
The SecurityContextLoginModule allows a Jaas based application to authenticate against Acegi.
