pam_mkhomedir causes segmentation fault after su

[Ed Sponsler]

I have RHEL 3.0 AS with ldap configured to authenticate and
pam_mkhomedir in /etc/pam.d/system-auth to create home directories if
they don't exist. Everything works fine, except when I su, which causes
segmentation fault.

Removing the pam_mkhomedir line in /etc/pam.d/system-auth fixes the su
problem, but of course I need that to make home directories.


[ed at wrk ed]$ ssh eds at ccdc

Creating directory '/home/eds'.

Creating directory '/home/eds/.kde/Autostart'.
/usr/X11R6/bin/xauth:  creating new authority file /home/eds/.Xauthority

// Yeah it works! But...
