This seems really strange posting this in reply to a post from one of
the samba devs, but I run a Samba4 AD DC on Debian 7.5 with bind9.9.5
and I have no problem in using nsupdate to update the DNS records. What
I did notice and it is probably a typo, is that your server is
127.0.0.21 not 127.0.0.1
I don't use ipv6 so this may be your problem, does the update work for
ipv4 addresses ?
