OK, winbind built into the samba daemon on the AD DC, is not the same as
the separate winbind daemon you would use on a member server It does not
have the same capabilities and is not setup in the same way, it cannot
pull the Unix attributes from AD and these have to be set in smb.conf
via templates. These templates mean that you cannot have different home
directories based on the user. The UID & GID numbers on the AD DC are
all in the 3000000 range, these numbers only exist on the DC, they will
be different on any member server (and any other DC's).
There are other reasons why you should not use an AD DC as a fileserver,
but the above reasons are the most obvious.
