Yeah, that's part of what I mean. They'll be stored on the file server
under those uid:gid. Make sure you have that information so that when
you go AD, you can add it to the DN of the users, whether you get the
upgrade script working or go with the adding the users from scratch. If
you use the same uid:gid AND you store those values alongside each user
in AD then you can use winbind to pull them from there. That way you can
be certain that they will be the same.
