Standard notice:  this sort of question belongs on kerberos at, not 
here.  This list is for issues relating to the MIT implementation of 
Kerberos itself.

That said, I've been down this path a few years ago.  The JMS standards 
explicitly exclude security.  What that means in practice is that if you 
get anything at all it's custom to the specific implementation, possibly 
insecure, and probably torques your code into decidedly non-portable shapes.

JMS was designed to be deployed on intranets behind firewalls.  The 
prevalence of "slow consumer" performance impacts is another symptom of 
the design target.

OTOH I see no fundamental reason why the standards should be 
incompatible with operating over GSSAPI connections.  If you have the 
resources to push an update to the JMS specification please go for it.

The opinions expressed in this message are mine,
not those of Caltech, JPL, NASA, or the US Government.
