After updating pam to pam-0.99.8.1-17, I started seeing pam errors
in /var/log/secure. Messages like:

I could not log in through gdm, although I could at a VT.
So I did an 'rpm -U --force pam-0.99.8.1-10.fc8.x86_64.rpm
pam-devel-0.99.8.1-10.fc8.x86_64.rpm'
I'm not sure if cron is fixed, but I can login through gdm now.
