Hello,

since a few weeks ago, I can type any password (or no one, if I want!) to unlock my session, to "su", "sudo", distant session, etc.

when I type "su", I'm logged as root without any ask for password.

I've already done some searchs, thanks to the thread I created last week here
http://forum.ubuntu-fr.org/viewtopic.php?id=1329581 (fr)

Please, can you give me some help?!

I havent installed anything "dangerous", I'm a java developper, and my office computer is used just for this (office).

Ubuntu 12.04 LTS 32bits

Mince, je suis sur un group français!
Excusez mon post en anglais, mais j'imagine que ça n'aura pas été un problème!

De quand date la dernière modification de /etc/pam.d/common-auth ?
Quel est son contenu ?

À quoi ressemble ton fichier /etc/passwd ? Y a-t-il bien comme dans le mien
un x dans le deuxième champ de chaque ligne ? Exemples :

root:x:0:0:root:/root:/bin/bash
titi:x:1002:1002:Titi:/home/titi:/bin/bash
