How to sync evolution contact categories to gmail contacts groups

view story

http://forums.fedoraforum.org – Hi, I am looking for 2 hours to find a way of synchronizing the categories in evolution contacts with gmail contacts groups. If found a thread in bugzilla for this claiming that is solved after evolution-server 3.*, but I cannot find a way to do this. Does anyone have a clue? It may sound stupid question, but when having 500 contacts grouping is elementary! Thanks in advance. (HowTos)
