Security unaware servers should clear this bit as per RFC1035 4.1.1.
RFC 4035 says that recursive servers MUST copy the CD bit to the response.
RFC 4035 says that servers SHOULD clear the CD bit for authoritative answers.
NSD 2.3.5 and before copied the CD flag to the answer. Fixed in NSD 2.3.6 and NSD 3.0.0. This also conforms to the behaviour of BIND 9.
