It sounds from that, that you are now using something like 
'myregistereddomain.com', if so, please don't, use 
'ad.myregistereddomain.com' or similar instead.

You only need:

[libdefaults]
     default_realm = EXAMPLE.COM
     dns_lookup_realm = false
     dns_lookup_kdc = true

> root at dc01:~# cat /etc/bind/named.conf.options

Try this version:

options {
         directory "/var/cache/bind";
         notify no;
         empty-zones-enable no;
         forwarders {
             8.8.8.8; 8.8.4.4;
         };

         dnssec-validation no;
         auth-nxdomain yes;
         listen-on-v6 { any; };

         // Use the first one of the next two lines if it exists, else 
use the last
         tkey-gssapi-keytab "/usr/local/samba/bind-dns/dns.keytab";
         //tkey-gssapi-keytab "/usr/local/samba/private/dns.keytab";
};

If that is really on one line, it should be two

It would seem that you are building Samba yourself, you can get 4.11 
packages from Louis's repo: http://apt.van-belle.nl/

He also does 4.12 packages for 20.04 and he has an howto for 18.04:

Probably worth a read ;-)
