| 32 | * Client-side object which queries a {@link RemoteAuthenticationManager} to | |
| 33 | * validate an authentication request. | |
| 34 | * | |
| 35 | * <P> | |
| 36 | * A new <code>Authentication</code> object is created by this class comprising | |
| 37 | * the request <code>Authentication</code> object's <code>principal</code>, | |
| 38 | * <code>credentials</code> and the <code>GrantedAuthority</code>[]s returned | |
| 39 | * by the <code>RemoteAuthenticationManager</code>. | |
| 40 | * </p> | |
| 41 | * | |
| 42 | * <P> | |
| 43 | * The <code>RemoteAuthenticationManager</code> should not require any special | |
| 44 | * username or password setting on the remoting client proxy factory to | |
| 45 | * execute the call. Instead the entire authentication request must be | |
| 46 | * encapsulated solely within the <code>Authentication</code> request object. | |
| 47 | * In practical terms this means the <code>RemoteAuthenticationManager</code> | |
| 48 | * will <B>not</B> be protected by BASIC or any other HTTP-level | |
| 49 | * authentication. | |
| 50 | * </p> | |
| 51 | * | |
| 52 | * <P> | |
| 53 | * If authentication fails, a <code>RemoteAuthenticationException</code> will | |
| 54 | * be thrown. This exception should be caught and displayed to the user, | |
| 55 | * enabling them to retry with alternative credentials etc. | |
| 56 | * </p> | |
