Boris Dushanov created WSS-501:
----------------------------------

             Summary: Kerberos token decoder default implementation fails to extract \
the session when validating a ticket issued by a KDC based on Active Directory  Key: \
WSS-501  URL: https://issues.apache.org/jira/browse/WSS-501
             Project: WSS4J
          Issue Type: Bug
          Components: WSS4J Core
    Affects Versions: 2.0.1
            Reporter: Boris Dushanov
            Assignee: Colm O hEigeartaigh


This issue is related to WSS-500.After fixing the service name form from \
NT_HOSTBASED_SERVICE to NT_USER_NAME in both Kerberos client/service actions I get \
the following exception while the service ticket is being validated and the session \
key is extracted from it :

Since Java 7, an Extended JGSS API is provided which is capable of extracting the \
session key in both retrieving and validating a service ticket.It is operable against \
both AD and ApacheDS KDC. That is proven by running KerberosTest against both types \
of KDC implementation.

I'm attaching an eclipse patch based on wss4j trunk, which is a proposition for a fix \
of the described defect based on the extended JGSS API. The patch also includes \
implementation for resolving WSS-500.
