One more further update.

Additional testing suggest that with Samba 4.5 not only is the manual 
addition of DNS records to the primary AD server required as suggested 
by Rowland and documented here 
when adding a second DC. An additional necessary step then also seems to 
be required afterwards. You must manually run samba-dnsupdate on ad2 to 
actually force the new DNS entries we just added to take effect.

~ pi at ad2 sudo samba-dnsupdate --use-samba-tool

Then restart samba-ad-dc, ie

~ pi at ad2 sudo systemctl restart samba-ad-dc
