The password is accepted at login and in tty.
Thanks
Fabio

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.

Reassigned because it don't update ~/pam_environement laying spurious from previous language

Why do you think this is a pam bug? The default sudo PAM configuration doesn't ever look at ~/.pam_environment - a recent fix to sudo now causes it to read /etc/environment where it previously failed to do so; but that was published *after* your bug report was filed, and certainly does not look at ~/.pam_environment.

Are there failures showing in syslog for these failed logins?

I cannot reproduce this behavior by changing the language variables in my environment.

[Fabio Marconi (fabiomarconi)]

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?

Reproduced in Precise too,in VirtualBox.
1- install Precise in Italian
2- update it, reboot
3- system-settings and select language support
4- click Install/Remove Languages and remove Italian
5- click on aply globally
6- verify that keyboard layout still Italian
7- reboot, open terminal and run a sudo gedit
The password will never be recognized.
Another strange things is that now .pam_environement isn't present in user directory (not present in Precise running in VM, but present in Quantal on real hardware . Quantal is a Quantal iso with old /home).

To Fix:
add the .pam_environement file containing the lines:
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
for english language, will fix the terminal and resume problem.

[Steve Langasek (vorlon)]

I cannot reproduce this using the steps described.

[Fabio Marconi (fabiomarconi)]

Hello Steve
I've tried again, (installed in italian, removed italian, apply globally without reboot and it already is triggering the bug)with this error:

May 28 20:42:00 njin-VirtualBox sudo: pam_unix(sudo:auth): authentication failure; logname=njin uid=1000 euid=0 tty=/dev/pts/0 ruser=njin rhost= user=njin

Hello,
I have similar issue if the password contains accentuated characters: I cannot login if the console is not configured to use the proper charset.
This issue is also present when pam is used to autheticate ftp or imap users with a non ascii password.
From what I have seen:
gftp, thunderbird, outlook auhthenticate using ISO8859
ios5 mail, konqueror, nautilus authenticate using UTF8

Could it be possible to include an option to convert pasword to/from utf/iso?

[Fabio Marconi (fabiomarconi)]

Reproduced and confirmed in latest quantal build, after reboot the keymap is mixed not English and not Italian.
Clicking on reset to default in layout settings, makes it working again

[Fabio Marconi (fabiomarconi)]

Damn, let system go into suspend and the password is no more accepted, relogins (unity-greeter) and it works, open the terminal and the map is mixed again.

[Fabio Marconi (fabiomarconi)]

before, instead of the è or à I've got ? , now without making any change it works, what happens ???

[Fabio Marconi (fabiomarconi)]

sorry, #17 not valid (i was using the installed system instead the VM .
then definitively has nothings to do with pam, but with keyboard mapping (at unity-greeter is working fine, but after not)
@stgraber, what do you think ?

[Fabio Marconi (fabiomarconi)]

Close as invalid because is better open a new one clean report
