change user with "su" is not permitted
Ciao all,
I'm a new user, I installed sabayon as a virtualbox guest machine with win7 host.
I have a problem: when I want to change user (root to user or user to root) I obtain a "Permesso negato" ("not permitted": italian language) message.
I can login with user or root as the first access (in X11/KDE or console) but I can't change user after that.
Doing "ls -l /bin/su" I obtain
"-rwsr-xr-x 1 root root"
Could you tell me how can I resolve this issue?
Thanks a lot.
