As it stands, when you create the share as shown on the wiki page:

# mkdir -p /srv/samba/Demo/

It ends up belonging to root:root with drwxr-xr-x permissions

Or to put it it another way the 'root' user has full permissions on
the directory, members of the 'root' group have read and enter
permissions, the same goes for any other users or groups. This all
means that members of the Domain Admins group cannot write to the

Try this:

chown root:Domain\ Admins /srv/samba/Demo/
chmod 0770 /srv/samba/Demo/

Now try to set the permissions from windows.

If this works and I am sure it will, I will update the wiki page.
