Ah, yes, I need to update that page.  To make this work on K12LTSP-EL5, you can
use the gdm from Fedora 6 this way: Download the source rpm file for gdm from
Fedora 6; you can find it at

Then, as root, run 'rpmbuild --rebuild gdm-'.  (Depending
on what you have installed on your system, you may get some errors about missing
dependencies; just use yum to install them all.  And rpmbuild comes from the
rpm-build package, which you can also install with yum.)  When rpmbuild
finishes, you'll have an rpm for a new gdm:

Install this with
rpm -Uvh /usr/src/redhat/RPMS/i386/gdm-2.16.5-2.i386.rpm

And then you'll need to restart gdm which will kick anyone logged in via GUI,
including you.  But then the timed auto-login should work.  I'll add this to
that wiki page.
