So, looking back at the error message you got:
FATAL: GSSAPI context error
DETAIL: Miscellaneous failure (see text): Decrypt integrity check
failed for checksum type hmac-sha1-96-aes256, key type
aes256-cts-hmac-sha1-96
FATAL: accepting GSS security context failed
DETAIL: Miscellaneous failure (see text): Decrypt integrity check
failed for checksum type hmac-sha1-96-aes256, key type
aes256-cts-hmac-sha1-96
(assuming that's still what you're getting..?)
What this is saying is basically that the key that the PG server is
using from its keytab and the key used to encrypt the ticket that the
user has (from the KDC) don't match up.
I wonder if somehow the keytab file that the server is using isn't
getting destroyed between the two test runs and so you're ending up with
the server using the key from the old KDC, while the user is using the
new one..? Or something is equally going wrong in the tests.
Could you try doing something like removing the 001_auth.pl, moving the
002_enc.pl to 001_enc.pl, double-check that everything is cleaned up and
that there aren't any old PG servers running, et al, and re-try that
way?
I've also reached out to some colleagues about having one of them test
with MacOS. What version are you on..?
Thanks!
