How to Import Active Directory groups to sharepoint SSP

Question

I want to add some rules to SSP Audiences and I can't access to Active Directory Groups in this rules.

When you want to add a rule you have 2 option: 1-User, 2-Property. I am using User option so I have to choose "Reports Under" or "Member of". When I choose Reports Under I can't find any AD Group in search popup.

I tried Full Import (you can find it in Shared Services Administration: SharedServices1> User Profile and Properties) as explained here but result was the same. Even in full import, I couldn't import Active Directory Groups. any suggestion?
