Thanks so much for pushing on it for so long, it’s a great feature to have!

I would love to see Kerberos/GSSAPI grow a way to find out what the
encryption used on the connection is, as we had discussed before... Do we
know if that encryption must match the encryption type of the tickets
acquired? Would it be possible to inspect the ticket in the same way that
klist does, to determine the encryption that must be used? And similarly
the key tab on the server side? Though of course there can be more than
one but maybe we can find out which was used?

Just some thoughts for future improvements here.

Thanks!

Stephen
