That should work.

If you are logged into the Windows machine as 'INTERNAL\Administrator'
it should work, but if you are using another Domain user, add that user
to the 'Domain Admins' group.

Something is going on here, 'ls' shows 'root:domain admins' as the
owner:group with 0770 permissions, but getfacl shows 'root:root' as
owner:group with 0755 permissions

'acl' is installed by default

It should and I have just updated that wiki page.

Double check Unix ownership and permissions on the share directory,
that is really the only thing that looks wrong.
To remove the ACL's and start again, run:
setfacl -b path/to/directory
reset the unix permissions as shown on the wiki page and then try again
