This is the version we test with in CI after the image update
in the next commit. This addresses the issues that were
fixed in CVE-2022-37967 (KrbtgtFullPacSignature) and ensures
that Samba builds against the MIT version that allows us to
avoid that attack.
The hooks to allow these expectations to be disabled in the tests
are kept for now, to allow this to be reverted or to test
older servers.
With MIT 1.21 as the new test standard for the MIT KDC build
we update the knownfail_mit_kdc - this was required regadless
after the CI image update.
Any update to the CI image, even an unrelated one, brings in
a new MIT Krb5, version 1.21-3 in this case. This has new
behaviour that needs to be noted in the knownfail files or
else the tests, which haven't changed, will fail and
pipelines won't pass.
(The image generated by the earlier bootstrap commit brought
in krb5-1.21-2 which was buggy with CVE-2023-39975)
Further tweaks to tests or the server should reduce the number
of knownfail entries, but this keeps the pipelines passing for now.

Windows erroneously shifts integer syntax claim values four bytes to the
right, resulting in incorrect values (if only one claim is present) or
corrupt claims data that cannot be unpacked (if other claims are

The 'etype' field in a Kerberos request is ordered. Make this fact
clearer by using a tuple or an array to represent etypes rather than a
set.
get_default_enctypes() now returns encryption types in order of
strength. As a consequence, the encryption type chosen by the MIT KDC
matches up with that chosen by Windows, and more tests begin to pass.
