[CentOS] tty login vs Gnome screen lock

I have a Centos 4.4 system (unpatched) that lets me log in via 
tty/console, but when the Gnone screen lock kicks in, my password is 
unable to unlock.   I am absolutely certain I an typing the correct 
password.  I had to Alt-F1 to log in that way, issue a sudo reboot, then 
logged back in, enabled the screen lock, typed my password again, and it 
would not unlock.

What am I missing?

Thanks.
