29 * This exception is thrown when
30 * the particular flavor of authentication requested is not supported.
31 * For example, if the program
32 * is attempting to use strong authentication but the directory/naming
33 * supports only simple authentication, this exception would be thrown.
34 * Identification of a particular flavor of authentication is
35 * provider- and server-specific. It may be specified using
36 * specific authentication schemes such
37 * those identified using SASL, or a generic authentication specifier
38 * (such as "simple" and "strong").
39 *<p>
40 * If the program wants to handle this exception in particular, it
41 * should catch AuthenticationNotSupportedException explicitly before
42 * attempting to catch NamingException. After catching
43 * <code>AuthenticationNotSupportedException</code>, the program could
44 * reattempt the authentication using a different authentication flavor
45 * by updating the resolved context's environment properties accordingly.
46 * <p>
47 * Synchronization and serialization issues that apply to NamingException
48 * apply directly here.
