+For DNSSEC, PowerDNS uses the Auth and Ordername fields in the database. This tests adds an (delegate) NS and A record
+to the test.dyndns zone, it also deletes these records. The test is rather big because it should cover
+all the scenario's.  This thus validates the correction of these records, known as rectify-zone and cache.

+to the test.dyndns zone, it also deletes these records. The test is rather big because it should cover
