 * Called by classes which make use of a {@link UserDetailsService} to check the status of
 * the loaded <tt>UserDetails</tt> object. Typically this will involve examining the
 * various flags associated with the account and raising an exception if the information
 * cannot be used (for example if the user account is locked or disabled), but a custom
 * implementation could perform any checks it wished.
 * <p>
 * The intention is that this interface should only be used for checks on the persistent
 * data associated with the user. It should not involved in making any authentication
 * decisions based on a submitted authentication request.
