I caught that Marc is updating the wiki. Good time to catch this item.

Do you mean /var/lib/samba/private/sam.ldb.d? That is where I am
finding files of interest. I do not have the directory you provided.
And what is the difference between:
I see named.conf in both. And the setup has other named.* files.
But the zone htt. is NOT in there, nor would I expect it to be. normally
MOST people use samba.mydomain.com and mydomain.com is found via the
forwarding. Of course there is no proper delegation of
samba.mydomain.com so other systems cannot resolve that subdomain. Here
I am building my own TLD, and want proper access elsewhere in my
internal network, thus the htt.zone file needed.
BTW, I do not see you using views in your named include files. From
what I got beaten up long ago on the DNS list (Mark Andrews and I go
back a long way in the IETF, so it is 'all in fun') that you MUST use views.

Not for the samba zone, but yes for other zones.
