  20 Tests for source4/dsdb/samdb/ldb_modules/password_hash.c

  23 io->ac->gpg_key_ids == NULL, so that the gpg supplemental credentials
  24 are not generated. And also need to be in an environment with a
  25 functional level less than 2008 to ensure the kerberos newer keys are not
  26 generated
