[Samba] Setting up new samba-ac-dc on Ubuntu 18.04 - KDC not FOUND

[Robert Steinmetz AIA]

OK I'm back on this after a tour through firewalld and other issues.

I see Louis has posted his  how to on git-hub. It seems very helpful

I also see his method uses the Ubuntu resolver but also uses bind9 so 
I'm not sure whether his method can be adapted to using the internal DNS 
in Samba.

In setting this up one of my main goals is to limit the amount of 
customization I do as I have found it easier to accept a little less 
performance for ease of maintenance.
