In my 'test' environment everything works as expected, except, as I
mentioned, any manually added static records that exist prior to the BDC
joining do not get replicated. New records, added by dhcpd etc, get
replicated without problem.
So, if I shutdown named and samba on the PDC, I'm still able to login
using the BDC and any new dns records are added to the BDC. This a test
environment and both servers are samba4.
