Fedora 20, clean install. I added the following lines to my sudoers file with visudo:
%power ALL=NOPASSWD: /sbin/shutdown
I then created group "power" and added my account to this group. Rebooted, confirmed that I was in the group with the "groups" command.
However, when I type "sudo shutdown" I am still prompted for a password.
I previously had my permissions group %power located in the sudoers file below root:
root ALL=(ALL) ALL
but above %wheel:
%wheel ALL=(ALL) ALL
It works now if I move it to below %wheel. Why is this?
