But what do you think about thins: As normal user I started redhat-config-network and logged out a little later without exiting it. Direcly logged in (I needed to restart the X server) again and redhat-config-network was restored WITHOUT ASKING FOR A PASSWORD!!!
This is a massive security problem I think!
When you start an application using Red Hat's consolehelper (which is what you're doing), you get a "keys" icon on your panel. Double click the icon and "forget authorization" before you log out.
If you file a bug, request that this application always "forget" when the process exits. The component is "usermode-gtk".
