I read through the wiki and the forums and saw that you can somehow automagically assign local workstation roles to certain domain groups by changing the description of the domain group to the local workstation role you wish to assign. I tried this but it does not make the members of the domain group have the specified local role.
For example, I have the domain group "students" with a description of "Power Users" in the server-manager groups section. When I log into an account ("student") that is a member of this domain group, the user does not have "Power Users" priviledges as I had hoped. Instead, when I use a windows console utility like "ismember.exe -l" or "net user student /domain", they tell me that I am indeed not a local "Power User" but a member of a global domain group called "Power Users" instead.
Is there a step I am missing in this? If this does not work as intended, I guess I will have to resort to manually adding the domain group(s) to the local "Power Users" role on every machine via the net command (through login scripts of course). I prefer the automagic way of course if possible

Also, I had one other small related question. When I create a user in the server-manager users section, it creates a domain group with the same name as the username I just created. I'm pretty sure this shouldn't be happening but then again I do not know what could be causing it. I cannot think of any contribs I installed that would have modified anything to do with the domain users or groups.
