That's the worrying part. Samba still issues tickets even with the wrong
(or no) dns registered in AD.

Hi
It doesn't matter if you add the record or not. It is the machine you
are joining which HAS to send it's own ID. The best (only way we've
found at least) way to do this is in /etc/hosts
127.0.0.1 member1.ts.mystuff.com member1 localhost

If you're dhcp, you'll also need some way to update the dns on the DC
although worryingly, as we just said, you can still get tickets with the
wrong or no IP in AD.
