Bug#495827: pam: Latest upgrade broke kdesktop_lock

2008-08-20 Thread Krzysztof Sobolewski 
Package: pam
Version: 1.0.1-2
Severity: normal


First of all I'm not a PAM expert, so forgive me if this report is totally 
misguided, but it's very visible so I could easily tell it was probably pam 
upgrade (after transition to testing) that caused this problem.
The thing is that I can login fine, but when I lock my screen (in KDE), I 
cannot unlock it other than by killing kdesktop_lock. The auth.log says:

Aug 20 20:05:11 zx-spectrum-1 unix_chkpwd[9390]: check pass; user unknown
Aug 20 20:05:11 zx-spectrum-1 unix_chkpwd[9390]: password check failed for user 
(jezuch)
Aug 20 20:05:11 zx-spectrum-1 unix_chkpwd[9391]: check pass; user unknown

user=jezuch

jezuch (invoked by uid 1000)

KDE was not upgraded recently.

This indicates that the unix_chkpwd helper is failing to retrieve the shadow
password entry for your user.  What are the permissions on /sbin/unix_chkpwd
and /etc/shadow on your system?  Are you using any unusual directory methods
on this system, such as NIS or NIS+?

Thanks,
