[gentoo-user] su doesn't work for me.
Hi, Gentoo. When, as a normal user, I type su, followed, when prompted, by the root password, I get the following error message: su: Permission denied . The return code is 1. I can't glean anything useful from the man page. Would somebody please tell me what I'm missing. Many thanks! -- Alan Mackenzie (Nuremberg, Germany).

It does add some security if you don't want a user, like maybe some little kid, getting root access for any reason. Dale :-) :-)
