Hi list, I've installed C 7.1.1503 and I've noticed that simple user can run from bash shutdown -h now/reboot without getting special permission (sudo, su). The machine is a VM without GUI (tested also on physical machine). From reddit I've got a suggestion: removing/comment out "-session optional pam_systemd.so" in /etc/pam.d/system-auth the problem is solved. This is a bug? If not, why use this policy? There are security implication? Thanks in advance.
