I have installed a zimbra server (open source version 6.0.8 on ubuntu hardy) in order to assess its features etc, and have hit a bit of a problem.
When I tryto create a new contact group, I am not able to add any contacts to it, only zimbra users. I need to be able to group the contacts in shared addressbooks. Is there a way I can go this, or is it not working as it should?

Cheers
Phill
