Package: libpam_cgfs
Version: 2.0.0~rc5-0ubuntu1~ubuntu14.04.1~ppa1
Host Version: Ubuntu 14.04 fully patched
Source of the package: http://ppa.launchpad.net/ubuntu-lxc/lxd-stable/ubuntu
Hey guys - quick report on a pretty bad regression in libpam_cgfs.
Effect: Total loss of admin privileges in Unity desktop even though
user is in group sudo.
Symptom: Options to modify settings in nm-applet are greyed out so
cannot control networking. Options to change user in users settings
greyed out etc.
Error Logs: gnome-session reports cannot get session. Is pam_systemd
being used?
It appears that the pam_systemd plugin is not present due to pam_cgfs.so
being in the pam session plugin configuration in /etc/pam.d/common-session.
If I comment this line
session optional pam_cgfs.so -c freezer,memory,name=systemd
Everything works again.
Conclusion something is broken in pam_cgfs.so and that's causing side
effects with other pam plugins and this ripples through all the way to
the desktop.
Cheers,
Peter
