Will this help me now or when I've fixed my mistake. I found this on http://devel-home.kde.org/~kppp/faq.html
How do I get rid of the password dialog (RedHat) ?
Red Hat chose to install kppp as a so-called consolehelper application. This PAM based mechanism avoids a setuid root installation. A quick and dirty solution to revert to the original behaviour is to delete the link to consolehelper and make the real binary setuid root. Open a terminal window, su to root and enter the following commands:
chmod u+s /usr/sbin/kppp
ln -s /usr/sbin/kppp /usr/bin/kppp
