[K12OSN] gnome login errors

[John Halfpenny]

hi. i'm having a real problem with gnome on a default install of k12 4.4.1.

i can only login to gnome with ldap users if i login as runlevel 3 first and then startx manually, root works fine from runlevel 5 startup.

after being told my login lasted for less than 10 seconds, the output of my error is this

/etc/X11/gdm/PreSession/Default: Registering your session with wtmp and utmp
/etc/X11/gdm/PreSession/Default: running: /usr/X11R6/bin/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x "/var/gdm/:0.Xservers" -h "" -l ":0" "john"
/etc/X11/xdm/Xsession: line 76: /usr/bin/ssh-agent /usr/bin/dbus-launch --exit-with-session gnome-session: No such file or directory
/etc/X11/xdm/Xsession: line 76: exec: /usr/bin/ssh-agent /usr/bin/dbus-launch --exit-with-session gnome-session: No such file or directory

i've been through umpteen searches on google and am totally stumped as to why i'm receiving this error. it seems to do it on my FC3 install and K12LTSP.

having been at it for the best part of two days i have tried all these things-

checked permissions on /tmp
checked permissions and availability on users home folder
checked disk space on both nfs and local server
uninstalled / reinstalled gnome-session
uninstalled / reinstalled gdm

i don't know which file it is referring to in the error, ssh-agent, dbus-launch and gnome-session are all in /usr/bin.

if anyone out there has any idea at all why this is happening i would be extremely grateful- as i've mentioned my users can all log into run level 3, and they can all run gnome if the machine starts up in run level 3 before starting x! 

how odd!

TIA

john
