Subject: xdm stops when login failed
Package: xdm
Version: 1:1.1.9-1
Severity: important

When login is incorrect, xdm fails to understand pam exit code and
stops. Here is log:


Sat Apr  3 23:32:33 2010 xdm info (pid 1709): sourcing /etc/X11/xdm/Xsetup
Sat Apr  3 23:32:38 2010 xdm error (pid 1709): pam_authenticate failure: Authentication failure
Sat Apr  3 23:32:38 2010 xdm error (pid 1695): Unknown session exit code 2816 from process 1709
Sat Apr  3 23:32:39 2010 xdm info (pid 1695): Exiting


PS.
This behavior appeared only after last xdm update.
