* An <code>AuthenticationManager</code> must honour the following contract concerning

* <ul>
* <li>A {@link DisabledException} must be thrown if an account is disabled and the
* <code>AuthenticationManager</code> can test for this state.</li>
* <li>A {@link LockedException} must be thrown if an account is locked and the

* <li>A {@link BadCredentialsException} must be thrown if incorrect credentials are

* <code>AuthenticationManager</code> must <B>always</B> test credentials.</li>
* </ul>
* Exceptions should be tested for and if applicable thrown in the order expressed
* above (i.e. if an account is disabled or locked, the authentication request is
* immediately rejected and the credentials testing process is not performed). This
* prevents credentials being tested against disabled or locked accounts.

* @return a fully authenticated object including credentials
* @throws AuthenticationException if authentication fails
