This is really the way to go and is the way the DC works, it will not
work if you do not have winbindd running. You don't have to use it on a
domain member, you just have to run it.

No, you don't have to keep them in sync, you create them in AD, give
them a gidNumber (this could be the one they had in /etc/group) and then
remove them from /etc/group.

The username map is now only really used to map 'Administrator' to the
Unix user 'root', anything else is old NT4
It is however your domain, so do it your way, whatever works for you :-)
