Setuping a stub zone on a Windows pointing to a Samba AD DNS server fails as it seems that Windows is doing a SOA request to Samba's DNS server and is expecting to get also a A and AAAA record of the mname server. In attached trace it's clear at packet 159 Windows is doing it when queried for its SOA record whereas in packet 198 we don't do it.
