After sending the email I realized that I did not mention that while
rebuilding the OS, I kept the "old" /srv/samba files. Which in turn
kept
the old permission settings. I think (could be wrong) that keeping the old
SID are now different from the new SID's created while rebuilding to
v4.12.6.

To answer your DC question:
root at dc1:~#  wbinfo -s S-1-5-21-589789-1426474111-2143966843-500
failed to call wbcLookupSid: WBC_ERR_DOMAIN_NOT_FOUND
Could not lookup sid S-1-5-21-589789-1426474111-2143966843-500

No firewall (ufw disabled, for the moment.)
