Tests for source4/dsdb/samdb/ldb_modules/password_hash.c
These tests need to be run in an environment in which
io->ac->gpg_key_ids == NULL, so that the gpg supplemental credentials
are not generated. And also need to be in an environment with a
functional level less than 2008 to ensure the kerberos newer keys are not
generated
