I think I’d move it further up the list to be the first thing listed. As all the other requirements seem obvious to a UNIX admin (UNIX users must have a shell, homedir, uid and gid) it’s easy to miss this one non-obvious requirement that a group that is meaningless to UNIX admins also needs to be changed. There’s also no warning there that the primary group of users should be left as “Domain Users” and not changed to match what the UNIX admin regards as that user’s primary group. I think I’d expect UNIX admins to be reading that section and they may have little, no or wrong knowledge of AD and AD builtin groups.
