[Samba] ISC's dhcp server, radvd and bind9 now adding samba as an AD DC

I had left my config alone for now and dhcp still writes to
DOMAIN1.SUBDOMAIN.TLD.  But samba has been complaining about not being able
to write to bind in its zone.

[2016/05/27 07:30:06.738434,  0]
../source4/dsdb/dns/dns_update.c:295(dnsupdate_nameupdate_done)
../source4/dsdb/dns/dns_update.c:295: Failed DNS update -
NT_STATUS_UNSUCCESSFUL

If you are right about it using kerberos I think I am missing a bit more
configuration to allow bind to use kerberos. I have a place for it to use
the key but nothing in it about kerberos and how to verify that.

You are going about this the wrong way, you do not setup dhcp and bind 
then add a Samba4 AD DC, you setup the AD DC with bind9 and then add the 
dhcp server.

[Samba] ISC's dhcp server, radvd and bind9 now adding samba as an AD DC

https://wiki.samba.org/index.php/Configure_BIND_as_backend_for_Samba_AD
helped me find that I needed to add

options {
     [...]
     tkey-gssapi-keytab "/usr/local/samba/private/dns.keytab";
     [...]
};

That seems to have fixed my errors with DNS
