Just throwing it out there... I'm not going to try it on my production network....
Maaan Tiger... ! You are forcing me to try it on my network! :P
I can't just let this go now.. heh!!

Oh well... I'm too busy right now to test it, but if nobody else does it, I will... ! HAVE to know now.. hehe!!

Just makes no sense to have it available at all, if it can only be used on the Domain level, to have it available on the OU level.. !
Or MS was just too lazy... easier to just leave it the same everywhere, even though it has no functionality.. ?!
