[krbdev.mit.edu #2210] GSSAPI accept_sec_context() sets INTEG andCONF flags producing inconsistent state with cleint

The flags might be what the client appl wants, but the SSPI might be
actually doing both because it only has an enctype that does both. 

So the protection on the packets may be more then the client requested.
So should the acceptor appl be told what the user requested, or what is
actually being used?
