I'm setting up OSX Lion Server (for the first time), and everything is fine, but I'm confused about physical storage. I want to set group access to certain files, applications, etc, but is all that data stored only on the server? Is there even a way to control applications, or must those be installed locally on client computers? Also, is there a way to force the client computer to always require a login to the server (i.e. no local access)? Just FYI: The client computers are stationary iMacs connected through Ethernet. Thanks!
