Many times I got warning/notice while accidentally tried to do some privileged action using my non-root account like below,
gulu@workpc:~$ sudo apt-get update [sudo] password for gulu: gulu is not in the sudoers file. This incident will be reported.
But when I logged into my sudoers account I never received any report of such an incident. Where are the reports reported?
How to access those? Or is it some trivial Warning message for non-sudoers?
