11   * This exception is thrown when an authentication error occurs while
12   * accessing the naming or directory service.
13   * An authentication error can happen, for example, when the credentials
14   * supplied by the user program is invalid or otherwise fails to
15   * authenticate the user to the naming/directory service.
16   *<p>
17   * If the program wants to handle this exception in particular, it
18   * should catch AuthenticationException explicitly before attempting to
19   * catch NamingException. After catching AuthenticationException, the
20   * program could reattempt the authentication by updating
21   * the resolved context's environment properties with the appropriate
22   * appropriate credentials.

24   * Synchronization and serialization issues that apply to NamingException
25   * apply directly here.
