[Bug 1162836] Re: likewise screws up PAM configuration for other services

[Michael Terry]

I've uploaded to precise.  Just waiting on sru approval now.  Thanks
Gunnar!  I'll unsubscribe sponsors now.

** Description changed:

- This is similar to #798277, however is a new problem. Please continue
- reading.
+ [Impact]
+ With likewise-open installed, the pam environment may not be read, causing some environment variables like PATH or LANG to be incorrect.
  
- Problem appears in lightdm 1.2.3-0ubuntu2.
- Downgrading to 1.2.3-0ubuntu1 resolves the problem.
- Upgrading to 1.2.3-0ubuntu2 again causes the problem to reappear.
- 
- Steps to reproduce:
+ [Test Case]
+ 0. Install likewise-open
  1. Login via lightdm
  2. Open a terminal.
  3. Run "echo $PATH"
  
  Expected result: the path contains the folder /usr/games like on earlier releases of Ubuntu.
  Actual result: PATH does not include /usr/games
  
  In addition, this causes PATH to not be set correctly after sudo. For
  instance, /usr/sbin is not in path after sudo. Once again, downgrading
  lightdm resolves the problem.
+ 
+ [Regression Potential]
+ This patch affects pam configuration, so could theoretically regress login behavior.  It's a minimal patch though and used in raring.
