Package: kdebase-bin
Version: 4:3.5.9.dfsg.1-5
Severity: critical
Justification: breaks unrelated software


After a recent upgrade (since 23 Aug 2008), our users, who can login
fine, cannot unlock the terminal after kdesktop_lock has locked it.
This appears to (possibly) be a PAM-related issue - here is what is
reported in auth.log when a user tries to unlock the terminal:

Aug 24 13:22:23 aspen unix_chkpwd[3472]: check pass; user unknown
Aug 24 13:22:23 aspen unix_chkpwd[3472]: password check failed for user (iamsteve)
Aug 24 13:22:23 aspen kcheckpass[3471]: pam_unix(kscreensaver:auth): authentication failure; logname=iamsteve uid=1000 euid=1000 tty=:0 ruser= rhost=  user=iamsteve
Aug 24 13:22:23 aspen kcheckpass[3471]: Authentication failure for iamsteve (invoked by uid 1000)

(the username 'iamsteve' and the user ID '1000' have been altered.)

I am thus cross-filing this bug with kdesktop (for kdesktop_lock),
kdebase-bin (for kcheckpass) and libpam-modules (for unix_chkpwd).
Please excuse the multiple postings, and please feel free to re-assign
this bug as appropriate.

As the user was able to log in prior to locking the screen, it doesn't
appear to be a problem related to the user per-se (i.e. the user exists
and is able to authenticate under some circumstances).

Note that I am not the only person with this problem:

  http://linux.derkeiler.com/Mailing-Lists/Debian/2008-08/msg01086.html

reports the same behavior in an unstable system (ours are testing)
as of 14 Aug 2008.

As with the above report, rebooting does not solve the problem.

Please be aware that we are *not* using LDAP or NIS/NIS+, and that I am
in no way affiliated with 'eric2 <dot> valette <at> orange-ftgroup <dot>
com' - this is not a simple re-reporting of bugs #478274 and/or #487932.

In addition to the information below, we are using:

ii  libpam-doc      1.0.1-3 Documentation of PAM
ii  libpam-modules  1.0.1-3 Pluggable Authentication Modules for PAM
ii  libpam-runtime  1.0.1-3 Runtime support for the PAM library
ii  libpam0g        1.0.1-3 Pluggable Authentication Modules library

Thank you for your attention to this matter.
