For the same reason I added a similar option to lorikeet-heimdal (my
branch of Heimdal for use in Samba4) for exactly the same reasons.  In
addition, we tend to find we are using netbios names, which makes DNS
doubly bogus.

I like your choice of name, but should this be a libdefaults or an
appdefaults issue?  (no-addresses seems to be under appdefaults in
