  * This exception is thrown when an authentication error occurs while

  * authenticate the user to the naming/directory service.

  *<p>

  * If the program wants to handle this exception in particular, it

  * should catch AuthenticationException explicitly before attempting to

  * catch NamingException. After catching AuthenticationException, the

  * program could reattempt the authentication by updating

  * appropriate credentials.

  * Synchronization and serialization issues that apply to NamingException

  * apply directly here.
