-/* PAM Make Home Dir module
-
-   This module will create a users home directory if it does not exist
-   when the session begins. This allows users to be present in central
-   database (such as nis, kerb or ldap) without using a distributed
-   file system or pre-creating a large number of directories.
-   
-   Here is a sample /etc/pam.d/login file for Debian GNU/Linux
-   2.1:
-   
-   auth       requisite  pam_securetty.so
-   auth       sufficient pam_ldap.so
-   auth       required   pam_pwdb.so
-   auth       optional   pam_group.so
-   auth       optional   pam_mail.so
-   account    requisite  pam_time.so
-   account    sufficient pam_ldap.so
-   account    required   pam_pwdb.so
-   session    required   pam_mkhomedir.so skel=/etc/skel/ umask=0022
-   session    required   pam_pwdb.so
-   session    optional   pam_lastlog.so
-   password   required   pam_pwdb.so   
-   
-   Released under the GNU LGPL version 2 or later
-   Originally written by Jason Gunthorpe <jgg@debian.org> Feb 1999
-   Structure taken from pam_lastlogin by Andrew Morgan 
-     <morgan@parc.power.net> 1996
