Comment 34 for bug 117736

This seems to still be a problem in 12.04. On log out I get

pam_mount(spawn.c:128): error setting uid to 0
pam_mount(mount.c:69): umount messages:
pam_mount(mount.c:73): umount: /home/me/share is not in the fstab (and you are not root)
pam_mount(mount.c:752): unmount of share failed

This seems to be a big problem if you log out, lose network connection, and log in using pam-mount. The computer locks up and the user is unable to log in without a reboot. It's easily reproducible.

With pam mount log in. Then log out. Verify mounts are still up. Bring down networking. Log in (using su is fine). The terminal hangs. You never log in.
