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