NTFS, SAMBA and DOS attributes

I'm having an issues with ufsd mounting a USB hard drive, then sharing it with SAMBA and retaining the DOS attributes when accessed via Windows system.

The mount command I'm using is:
mount -t ufsd -o noatime,sparse,nls=utf8,force,acl,user_xattr (dev) (mnt point)

I've modified my smb.conf file to include the following:
ea support = yes
store dos attributes = yes
map readonly = no
map archive = no
map system = no

The issue is when I connect to the host with a windows client, and try to change the DOS attributes, they aren't.

Example from a windows machine:
Z:\>attrib +h +s +r +a test.txt

Z:\>attrib test.txt
Z:\test.txt

So, how can I get the USFD driver to maintain/update DOS attributes?

P.S.
Sorry but I am using this on a Linux system. But I can't find a sub forum for Linux. MAC is "Unix" so I thought I would try here.
