[Samba] Home Directories on the fly?

[Golden Butler]

Hello all,
I have a functional samba/windind file server (SLES 10) thats a member server of an Active Directory domain.  I'm able to successfully resolve user and group accounts from AD.  The problem I'm having is samba isn't creating home directories automatically when I try to map to a AD user share from Win XP.  What I am able to do is, when I ssh into the machine with an AD user, it creates the the home directory.  I can't figure out why because my pam.d configs are configured for this to happen.  But obviously I'm missing something.  One thing I did try as a result from googling is changing the /home/MYDOM directory to 777, but no cigar.  Here's my pam.d configs and smb.conf below.  Thanks in advance.

/etc/pam.d/samba:
auth     include        common-auth
account  include        common-account
password include        common-password
session  include        common-session

/etc/pam.d/sshd
auth     include        common-auth
auth     required       pam_nologin.so
account  include        common-account
password include        common-password
session  include        common-session

/etc/pam.d/common-session
session required        pam_mkhomedir.so
session required        pam_limits.so
session required        pam_unix2.so
