What happened to PolicyKit?

view story

http://askubuntu.com – Back in 8.04 or so, when PolicyKit was new, we had a GUI "browser" that enabled us to easily decide things like whether a user should be allowed to shutdown the system when other users were logged in and if it should always be allowed or only while on the console, etc. Then those things suddenly disappeared and though it seems PolicyKit is still in use, I haven't been able to find any similar GUI to actually configure the policies. What happened? (HowTos)
