[Samba] DNS logging for TLD queries?

First you should really upgrade to 4.7.4 (see recent changelog)

Second, if you are not using Bind DLZ, you should set it up, it works 
much better than the internal DNS engine.

And third it is then just a matter of configuring Bind properly, you can 
check our wiki at the following address (yeah, it's in French, but it 
shouldn't be too much of a hassle for your favorite translation tool):

Actually we had exactly the same question from a client a few month ago...

Cheers, and happy new year 2018!
