72f82d949a CVE-2020-25719 tests/krb5: Add expected parameters to cache key for obtaining tickets
If multiple calls to get_tgt() or get_service_ticket() specify different
expected parameters, we want to perform the request again so that the
checking can be performed, rather than reusing a previously obtained
ticket and potentially skipping checks.

It should be fine to cache tickets with the same expected parameters, as
tickets that fail to be obtained will not be stored in the cache, so the
checking will happen for every call.

72a2c21f3f CVE-2020-25722 samba-tool spn add: remove --force option
This did not actually *force* the creation of a duplicate SPN, it just
ignored the client-side check for the existing copy. Soon we are going
to enforce SPN uniqueness on the server side, and this --force will not
work. This will make the --force test fail, and if that tests fail, so
will others that depend the duplicate values. So we remove those tests.

It is wrong-headed to try to make duplicate SPNs in any case, which is
probably why there is no sign of anyone ever having used this option.

no PAC is available.

For now we want to look for ACCESS_DENIED as this allows
the test to pass (showing that gensec:require_pac = true
is a useful partial mitigation).

This will also help others doing backports that do not
take the full patch set.
