I've now made it so secure I can only log in as root by physically accessing the machine. When I perform su with my personal account I get an incorrect password error. I assume that whatever checks the password needs to run as root and is denied access it requires. Generally I would like more clarity on what happens when an su command is issued. I welcome your insights, thanks!</p>mdurWed, 19 May 2010 14:06:37 -0400http://linuxexchange.org/questions/660/fedora-12-when-i-perform-su-as-a-normal-user-what-checks-the-passwordsurootchmod
