Can I use Active Directory Groups for my AFP Share?

I'm playing around with AD authentication and seem to have an issue when I make an AFP share... when I assign the "Owner" I can take a name from AD and it populates the Owner field. However, when I try to drag an AD group over, it bounces back to the list -- it won't work. I read an earlier post about creating a local group, then adding AD users into the group -- is that the ONLY way to use AD authentication? So, in other words, can I use AD GROUPS... or no? Sure hope so... :) Any thoughts are appreciated... -Sapridyne
