Unfortunately not.  In my haste to make the two /etc/pam.d directories 
match, I deleted the .orig files.  I should have moved them.  I'll build 
another 12.04 machine and see if I can replicate this.

To my knowledge, I hadn't modified them.  I can't think of a reason why I 
would have.

Unfortunately again, no, I didn't test between the two actions.

Title:
  UI Permission Problems After Upgrade from 12.04 to 14.04

Status in “pam” package in Ubuntu:
  Incomplete

Bug description:
  I upgraded a machine from Ubuntu 12.04 to 14.04 using "update-manager
  -d".  After upgrading, rebooting, and logging back in, I had various
  user permission problems: I could not change anything in Network
  Manager, update-manager told me "Not authorized to perform operation"
  when I launched it, sound did not work, Synaptic would not launch from
  Dash, etc.  Looking for existing bug reports, I found bug 1240336
  which suggested to me that this might be a PAM-related problem.  I
  then compared the contents of /etc/pam.d to a machine that was freshly
  installed with 14.04.  Running "pam-auth-update --force" eliminated
  most of the differences.  Additionally, I removed the libpam-ck-
  connector package (which seems to not be needed?).  After this, this
  /etc/pam.d matched the freshly installed system.  After logging out
  and back in, the problems were resolved.
