See Article: http://community.centrify.com/t5/DirectControl-Express-for-UNIX/Automounting-home-directories-defined-in-AD/td-p/1044

* Disclaimer: I did not create (write) this script, or have I tested this well. Please change any errors or omissions in these instructions! *

1. Install SAMBA.

OPEN TERMINAL with Ctrl-T if it is not already open

   sudo -i

   apt-get update
  
   apt-get install samba

2. Create Script with adhome.pl based on article above and place in /usr/bin/adhome.pl

   sudo -i

   nano /usr/bin/adhome.pl

2a. Copy the Shell Script into adhome.pl

    #!/bin/sh /usr/share/centrifydc/perl/run
     # This script uses ldap to fetch user homeDirectory from AD 
     # and mount/umount by smbmount and smbumount
    use strict;
    #use MIME::Base64;
    use File::Spec;
    # get base dn
    my $zone_base = `cat /va/centrifydc/kset.zonename`;
    #get user CN
    my $cn = `adquery user -D ${ARGV[0]} | cut -d, -f1`;
    #print $cn;
    my @cn = split(/\n/,$cn);
    #ldap search
    #search for the homeDirectory attribute of user in AD in autozone mode
    #also cut the path out and change backward slash to forward slash
    my $ldap = `/usr/share/centrifydc/bin/ldapsearch -Q -H "LDAP://" -b "$zone_base"  -LLL "(@cn)" homeDirectory | grep homeDirectory | cut -d: -f2 | sed 's:\\\\:/:g' `; <\nowiki>
     <nowiki>#print $ldap;<\nowiki>
     <nowiki>#split the output into single line
    my @line = split(/\n/, $ldap);
    #print @line;
    #if ldapsearch result is not blank
    if (@line )
    {
    if(${ARGV[2]} eq "mount") {
    #mount the homeDirectory with smbmount command on mountpoint with kerberos ticket
   my $mount = `smbmount @line ${ARGV[1]} -o sec=krb5i`;
   #    print "mount";
     }
   }
   #if argument3 is umount will umount the share
   if(${ARGV[2]} eq "umount" ){
   my $mount = `smbumount ${ARGV[1]}`;
   #    print "umount"
