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.
