  * This exception is thrown when an authentication error occurs while

  * An authentication error can happen, for example, when the credentials
  * supplied by the user program is invalid or otherwise fails to
  * 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
  * the resolved context's environment properties with the appropriate
  * appropriate credentials.
  * <p>
  * Synchronization and serialization issues that apply to NamingException
  * apply directly here.
