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.
