11   * This exception is thrown when
12   * the particular flavor of authentication requested is not supported.
13   * For example, if the program
14   * is attempting to use strong authentication but the directory/naming
15   * supports only simple authentication, this exception would be thrown.
16   * Identification of a particular flavor of authentication is
17   * provider- and server-specific. It may be specified using
18   * specific authentication schemes such
19   * those identified using SASL, or a generic authentication specifier
20   * (such as "simple" and "strong").
21   *<p>
22   * If the program wants to handle this exception in particular, it
23   * should catch AuthenticationNotSupportedException explicitly before
24   * attempting to catch NamingException. After catching
25   * <code>AuthenticationNotSupportedException</code>, the program could
26   * reattempt the authentication using a different authentication flavor
27   * by updating the resolved context's environment properties accordingly.
28   * <p>
29   * Synchronization and serialization issues that apply to NamingException
30   * apply directly here.
