Class PreAuthenticatedAuthenticationProvider

java.lang.Object
  org.springframework.security.providers.preauth.PreAuthenticatedAuthenticationProvider

All Implemented Interfaces:

InitializingBean, Ordered, AuthenticationProvider

public class PreAuthenticatedAuthenticationProvider
extends Object
implements AuthenticationProvider, InitializingBean, Ordered

Processes a pre-authenticated authentication request. The request will typically originate from a AbstractPreAuthenticatedProcessingFilter subclass.

This authentication provider will not perform any checks on authentication requests, as they should already be pre- authenticated. However, the AuthenticationUserDetailsService implementation may still throw a UsernameNotFoundException, for example.

AuthenticationException - if authentication fails.

supports

public boolean supports(Class authentication)

Indicate that this provider only supports PreAuthenticatedAuthenticationToken (sub)classes.

Specified by:

supports in interface AuthenticationProvider

Parameters:

authentication - DOCUMENT ME!
