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.
