 ==== PreAuthenticatedAuthenticationProvider
-The pre-authenticated provider has little more to do than load the `UserDetails` object for the user. It does this by delegating to a `AuthenticationUserDetailsService`. The latter is similar to the standard `UserDetailsService` but takes an `Authentication` object rather than just user name:

-This interface may have also other uses but with pre-authentication it allows access to the authorities which were packaged in the `Authentication` object, as we saw in the previous section. the `PreAuthenticatedGrantedAuthoritiesUserDetailsService` class does this. Alternatively, it may delegate to a standard `UserDetailsService` via the `UserDetailsByNameServiceWrapper` implementation.

 ==== Http403ForbiddenEntryPoint
 The `AuthenticationEntryPoint` was discussed in the <<tech-intro-auth-entry-point,technical overview>> chapter. Normally it is responsible for kick-starting the authentication process for an unauthenticated user (when they try to access a protected resource), but in the pre-authenticated case this doesn't apply. You would only configure the `ExceptionTranslationFilter` with an instance of this class if you aren't using pre-authentication in combination with other authentication mechanisms. It will be called if the user is rejected by the `AbstractPreAuthenticatedProcessingFilter` resulting in a null authentication. It always returns a `403`-forbidden response code if called.
