The module initially only supported device based authentication. IFAIK account based authentication (Samba 4 / LDAP) was never added to the module.
I think it would be best to start with an installation howto with account based authentication enabled.
If you are willing to try installing it (on a test machine) and document the process, I am sure the rest of the community will chip in with testing and fine tuning the install howto.
When we have a fool-proof install howto, we can try creating a complete module / rpm for easy install.

@gmue, What do you think?
