dseditgroup not finding group to add to local domain.

For years now have had trouble getting the Allow Administration by field to work properly in OS X. It wasn't a problem before I just ignored it but I can't any longer.

It doesn't work through the GUI, and when I try via command line

sudo dseditgroup -o edit -a “DOMAIN\domain admins” -t group admin

where DOMAIN is the name of my domain (in all caps) the response back is "Group not found"

Any ideas? The computer is bound to the domain, and authenticates just fine of AD accounts. Just can't seem to give local admin rights to the right people (well anyone with an AD account)
