I thought accepting TCP as well as UDP was the default setup.  In
fact, we updated the MIT implementation to support TCP because we've
run into situations where KDC responses from MS KDCs were too big to
be returned by UDP.  Except for cases like that, though, the KDC will
send its response using the same protocol the client used to
communicate with the KDC in the first place.  (Even in the
too-big-for-UDP case, if the client used UDP, the KDC will use UDP to
send back an error code that means the client should try again with
TCP.)
