Thank you guys!
Both of your answers pointed me in the right directorion, that is, look into journalctl for the sudo log, and it was indeed there.
Just a small note: at least in openSUSE 13.2,
journalctl does not have a
-t option, so I just did
Code:
journalctl | grep sudo
as a quick inspection and that did the trick.
I am marking these thread as solved and your replies as helpful. Thanks again!
