After running linuxconf in gnome as root, setting an NIS domain and NIS server, and activating the changes, linuxconf propoerly edits /etc/yp.conf, but does not cause ypbind to be started when entering any run level. You still have to do a 'chkconfig --level 345 ypbind on' to bind to an NIS domain in any of the multi-user run levels. I also didn't see a way to edit/set features controlled by /etc/nsswitch.conf, or /etc/hosts, /etc/passwd, /etc/group. I'm not sure if that's a bug report or a feature request... :)
The back-end controls what the gnome-linuxconf front-end does, so I'm reassigning this to the linuxconf component. The /usr/sbin/authconfig tool available from /usr/sbin/setup in RHL 7 includes this functionality as well.
Closing because we don't ship linuxconf anymore
