How can I change the location Server.app creates new folders?

Hi!

Running a Lion Server I have decided to move /Users and /Groups to another partition but now when I create a user or group no user or group share is created. Groups aren't that much of a problem since I can create those manually, but user homes.

I have in server.app pointed the new location out as sharepoint both users and groups point to the right place, but there's probaaby a terminal command to run somewhere here....
