The tests are really fast enough with one KDC that I don't think it
makes sense to have two independent tests.

Ah, good to know that's what was happening.

Please find attached a patch which updates the protocol.sgml docs that
Michael mentioned before, and merges the tests into one test file (while
adding in some additional tests to make sure that the server also agrees
with what our expectations are, using the pg_stat_gssapi view).

I'll push this soon unless there are concerns.  If you get a chance to
test the patch out, that would be great.  It's working happily for me
locally.

Thanks!

Stephen
