Title:
  session optional pam_systemd.so missing from /etc/pam.d common-session
  file

Status in “systemd” package in Ubuntu:
  Confirmed

Bug description:
  session optional pam_systemd.so missing from /etc/pam.d common-session
  file

  I updated from 12.04 to 13.10 version three days back. After this I
  noticed,

  1. the shutdown and restart options from the top right corner button did not work.
  2. My user name was not being diplayed next to the top right corner button.

  From #ubuntu-bug irc chat a user helped me identify the issue.

  We started from the /var/log/syslog showing "Oct 24 22:54:58
  c490100005 gnome-session[1984]: WARNING: Unable to inhibit system:
  GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Operation not
  permitted" when I tried doing a shutdown/restart.

  Then we ran the following commands with the following results,

  command: dbus-send --print-reply --system --dest=org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager.CanPowerOff
  result: method return sender=:1.3 -> dest=:1.95 reply_serial=2
     string "challenge"

  command: loginctl list-sessions
  result: 0 sessions listed.

  command: cat /etc/pam.d/common-session | grep systemd
  result: returned nothing

  So we added the line "session optional        pam_systemd.so" to the
  common-session file and the above two issues are now gone.

  (UPDATE:)
  To add further information, this is how i upgraded my system from 12.04 to 13.10,

  1. logged into the system with my normal user account, (which is not in the sudoers list)
  2. opened terminal and did "su <sudoerAccountName>" and then entered the pwd.
  3. once inside the sudoer account in the terminal, I issued the command "sudo update-manager -d"

  I did the above three steps from 12.04 to 12.10, 12.10 to 13.04 and
  finally from 13.04 to 13.10.

  I was not able to update directly to 13.10, hence the step by step
  approach.
