  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.
