Now that I know that one can manage DNS using samba-tool, let me do some 
further testing.  So far I've *never* made any manual changes to the DNS 
zones. It happens automatically when I join the domain (this is also how 
it works with a Windows AD DC AFAIK). I checked with one of my Windows 
colleagues, and he confirmed that both the A and PTR records are created 
automatically when using Windows servers.

If the DNS entry is created automatically, it needs to be removed, too, 
and that did seem to happen the first time I left the domain.  Will test 
again now.
