>Can someone give me an example of how to create an object reference I can use to set/get these "Organizational-Person" properties?

Check out this Microsoft KB article. It's an ADSI browser, and I'm pretty sure it will show you how to get what you're looking for. Off the top of my head, check the forms EnumObjects method which demonstrates how to filter on objects, including groups. You just need to check the objects Class property.
