[Bug 1176910] [NEW] pam-auth-update can fail during raring -> saucy upgrade leading you to a broken session

[Didier Roche]

Public bug reported:

Context: a year ago, I added fingerprint support to my pam configuration
(and then removed it)

During the raring -> saucy upgrade /usr/sbin/pam-auth-update failed (it needs --force), running it manually was telling me:
pam-auth-update: Local modifications to /etc/pam.d/common-*, not updating.
pam-auth-update: Run pam-auth-update --force to override.

The consequence is that as I have no system-logind support after it, I have my user not added in any group:
- no hw accel (as not in the video group)
- no sound (no audio/pulse group)
- no nm-applet showing…

I'm attaching the old common-session pam configuration, before forcing the update. I have also some .pam-old files
After forcing it, I have:
+sessio noptional pam_winbind.so
+session optional pam_systemd.so
and everything is back to normal (my user is now dynamically added to the relevant groups)
