I’ve looked around in the menus and googled this, but I can’t find a way to make the login require a username instead of just showing the available users to select from.

Switch to KDM instead of GDM as the default display manager. This will change the login screen and require typing a username which is much more secure. It will not change your desktop but you may have to select GNOME or KDE the first time you log in if you have both installed.

Alternatively, you can edit /etc/gconf/gconf.xml.defaults/%gconf-tree.xml directly.
install configuration editor 2.28.0
yum install gconf-editor.x86_64
go to gdm in the tree view and expand
click simple-greeter
right click disable_user_list and choose set as default (enter root pw)
right click disable_user_list and choose set as mandatory (enter root pw)
logout

Right, if the next release/subrelease doesn’t change where the file is, and of course editing .xml files is sooo much better than, say, plain text files.
Or, as someone suggested, you could use kdm for login, and right *there*
it offers you a choice of which window manager to use, as opposed to gnome, that wants to lock you in, like, say, someone north of Seattle….
mark “me? anti-gnome?”
We’ve added the following line to our postinstall scripts.
