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").
If the program wants to handle this exception in particular, it
should catch AuthenticationNotSupportedException explicitly before
attempting to catch NamingException. After catching
AuthenticationNotSupportedException , the program could
reattempt the authentication using a different authentication flavor
by updating the resolved context's environment properties accordingly.
Synchronization and serialization issues that apply to NamingException
apply directly here. |
