The above is interesting, you don't have a template homedir line in
smb.conf but you have '/home/username' instead of '/home/RW/username'

On a Samba AD DC, 'Domain Users' should be mapped to the users group
(on Debian anyway, could be a different group on freebsd), but your
example seems to show that it is mapped to the group 'staff'.

Here is the big thing that people seem to find hard to understand, when
asking for the users info with 'getent passwd' the users 'gidNumber
attribute is ignored, in fact, the user doesn't need to have a
gidNumber. In AD, all users are members of 'Domain Users' and this group
is used as the Unix users primary group.
