[Bug 1094978] [NEW] pam environment duplicate path directories

[Ayrton Araújo]

Public bug reported:

Using Ubuntu 12.10, if I set up my ~/.pam_environment like this:
PATH DEFAULT=${PATH}:~/opt/bin
My PATH will have ~/opt/bin seted twice.

For fix this, I need to do the following change in line 50 of file /etc/pam.d/login:
session       required   pam_env.so readenv=1 user_readenv=0
While user_readenv=0 avoid to set env using my local changes and call my personal env in the second time session is called.

** Affects: pam (Ubuntu)
     Importance: Undecided
         Status: Confirmed
