[Bug 1001755] Re: After changing language, password no more accepted in terminal and at resume from suspend

[Fabio Marconi]

Hello Steve
I've assigned this to pam just because I don't know who manage ~/.pam_environement but as it is a pam file, probalby is related to it.
I've also found this error (before remove that lines) in auth.log but nothing on syslog:

quantic sudo: pam_unix(sudo:auth): authentication failure; logname=njin
uid=1000 euid=0 tty=/dev/pts/0 ruser=njin rhost= user=njin

I've tried to add again that lines to my 'reinstalled' system (with the old /home) reboot and I can reproduce it.
So I want to know who manage this file during the change of the language process and why it ley back that two residual lines.
I'm going to reinstall Precise changing language and try again if it reproduces.
Thanks
Fabio

Can you also point me to a valid documentation on pam and how it works?

  I've tried to recreate the user, reinstall keeping my home, but it exist again.
  On another machine at same level, the bug not appear
  If I create another user, it is not affected, so i'm thinking at something in my home dir that is the only thing not changed, but what ?

  **Workaround**
  gedit ~/.pam_environement
  and removed:
  LANGUAGE=it_IT:en
  LANG=it_IT.UTF-8

  to have the file like this:
  LC_NUMERIC=en_US.UTF-8
  LC_TIME=en_US.UTF-8
  LC_MONETARY=en_US.UTF-8
  LC_PAPER=en_US.UTF-8
  LC_NAME=en_US.UTF-8
  LC_ADDRESS=en_US.UTF-8
  LC_TELEPHONE=en_US.UTF-8
  LC_MEASUREMENT=en_US.UTF-8
  LC_IDENTIFICATION=en_US.UTF-8
  It works as expected.
