I believe that means it has never replicated to AUTH1.

I am not sure. Maybe this is relevant, although it's quite old:
> How does DNS replication work here? I followed this: https://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC#Check_required_DNS_entries_of_the_new_host and had to add A record by hand and also the CNAME record. When it comes to the last step which I believe to be setting the name server to the newly provisioned replicated domain's own internal DNS (I'm using internal DNS), I set /etc/resolv.conf to point at <IP address> at which point DNS won't resolve anything. Is there something I can check here to ensure this is working or do I have the wrong idea altogether here?
I've not tried this, but I think that should work. If you try
querying the second DC with samba-tool do you see the DNS records?
