shutdown that comes with usermod still allows any user to shutdown a system? Fixed in other RH version but it still in RH7.0 , so is this a bug or a feature?
Are these users logged in at the console when they shut the machine down? If so, then it is working as designed (given shutdown and a power switch, shutdown is preferable). If the user is not logged in at the console and can shut the machine down, it is a security bug.
[anyuser@machine anyuser]$ shutdown shutdown: you must be root to do that! Closing this. cheers, Jindrich
