Attached debdiff between trusty-updates and SRU.

** Branch unlinked: lp:~unity-team/unity/trusty-1305440

** Description changed:

+ [Impact]
+ 
  It might be desirable to have a distinct pam config file when logging in
  and when unlocking the screen. Specifically, using a fingerprint reader
  is fine for sudo or for unlocking, but you want to use your password
  when logging in, to provide a secret and be able to unlock the gnome-
  keyring for example.
+ 
+ [Test Case]
  
  See http://askubuntu.com/questions/445131/how-do-i-enable-a-specific-
  pam-config-in-the-lockscreen
  
  So this feature request is about allowing for a (optional) pam config
  file for the lock-screen, distinct from the /etc/pam.d/lightdm currently
  used and shared with the greeter.
+ 
+ [Regression Potential]
+ 
+ An additional configuration point could allow a system to be
+ misconfigured for reduced security.  The default configuration is to use
+ the same PAM stack as the LightDM login process so no new regression is
+ introduced without user modification.
+ 
+ [Other Info]
+ 
+ The Ubuntu 14.04 LTS SRU patch was cherry-picked from Ubuntu 14.10 where
+ it has been in production use for a few months and appears stable.
