java.lang.Object org.springframework.security.providers.rcp.RemoteAuthenticationProvider
public class RemoteAuthenticationProvider
Client-side object which queries a RemoteAuthenticationManager
to validate an authentication request.
A
new Authentication
object is created by this class comprising the request Authentication
object's principal
, credentials
and the GrantedAuthority
[]s returned by the
RemoteAuthenticationManager
.
The RemoteAuthenticationManager
should not require any special username or password setting on
the remoting client proxy factory to execute the call. Instead the entire authentication request must be
encapsulated solely within the Authentication
request object. In practical terms this means the
RemoteAuthenticationManager
will not be protected by BASIC or any other HTTP-level
authentication.
If authentication fails, a RemoteAuthenticationException
will be thrown. This exception should
be caught and displayed to the user, enabling them to retry with alternative credentials etc.

Returning true
does not guarantee an AuthenticationProvider
will be able to
authenticate the presented instance of the Authentication

closer evaluation of it. An AuthenticationProvider
can still return null
from the
AuthenticationProvider.authenticate(Authentication)
method to indicate another AuthenticationProvider
should be
tried.
