You are still using samba-4.0.0 - a lot of stuff has changed
over time - recent is 4.0.4.
I'm a bit wondering about
;; WARNING: recursion requested but not available
in the failing dig command.
In former samba versions there _was_ a [global] smb.conf option
recursive queries = yes
samba-tool testparm -v --suppress-prompt should list all
Can you try that one, if valid?
ps - i possible, you should upgrade samba!
