ODBC driver should work with it - I don't know exactly how they plug
into libpqs auth, but IIRC they do some stuff to make that work.

Note that I'm only talking about being mutually exclusiv ewith MIT KRB
GSSAPI, not with MIT KRB in "krb5" mode. Though I very much want to
deprecate the "native kerberos" auth in favor of GSSAPI as soon as
possible for several reasons, so I'd suggest you don't use that once you
go to 8.3 ;-)

I have my Unix machines in the Active Directory, so there's no cross
realm. It works fine.
And if you don't trust the key, put it over SSL? ;-) If you use SSL,
GSSAPI packets actually go through the SSL tunnel, unlike krb5 auth.

Yes, there's still support for doing GSSAPI with MIT KRB5. It's just
that you have to use it *instead* of SSPI. So a rebuild is necessary.

But - IIRC, you can just join your windows machine to your unix kerberos
realm and be done with it - SSPI APIs should work fine in that case.
