Samba POSIX Permissions Problems

I’ve been searching for about a week off and on now and testing many potential solutions and still have found no way to fix a permissions problem I am having!
I’m using OS X Leopard Server 10.5.6 to host a Samba share for use as a home folder for Windows clients. The Server is in a dual directory configuration (bound to both Open Directory and Active Directory). I can authenticate, single sign-on works, and mcx and GPO settings are operational. When a user signs into Windows for the first time and the Redirected Folders policy is applied, the Samba share is mounted, redirects the local “My Documents” folder and seems to copy the contents to the share correctly. Within Windows, the owner is able to access all the folders within his/her profile and My Documents folder as well.

The only issue is when a user decides to sign in to a OS X client they do not have permission to access their own “My Documents” folder now on the Samba share. The POSIX permissions for the “My Documents” folder is set to 000 for some reason but with correct ownership. It seems that regardless of whether I use the option of inherit permissions or not on the Samba share the same error happens. Also, I’ve tried to specify the “force directory mask = 0500” directive to mandate at least Read access to the owner’s own folders so they can access and browse them in OS X to no avail.

Contents of /var/samba/shares/users:

#VERSION 3
path=/Volumes/Data Set/Users
comment=Users
usershare_acl=S-1-1-0:F
guest ok=no
inherit permissions=no
oplocks=yes
directory mask=0755
force directory mask=0500
strict locking=no
create mask=0755

POSIX Directory permissions after Windows redirects ‘My Documents’ folder:
