Problem with ldm + pam_mount (with patch)

Hi,

When I use ldm with pam_mount i've a problem.

When I log out my session on a thin client, pam_mount don't unmount
partitions. The problem is that master ssh is killed when x session
ended.

Here is the command:

"/usr/bin/ssh -X -t -S /var/run/ldm_socket_vt1_192.168.231.195 -l
leo.bontemps 192.168.231.195 LTSP_CLIENT=192.168.231.30
PULSE_SERVER=tcp:192.168.231.30:4713
ESPEAKER=192.168.231.30:16001 /etc/X11/Xsession ; /usr/sbin/ltspfsmounter all cleanup; kill -1 ${PPID}"

It should be greater to use"-O" option of ssh to exit the ssh master
rather than "kill" it.

If I do that, ssh session is ending perfectly et pam_mount unmount all
my partitions. I think so it's a better way to stop ssh connection
sharing.

I send you a patch in attachment.

Regards,

GARETTE Emmanuel
