Are there any config options needed within smb.conf that must exist to use this feature?
Yes, there are. Instead of listing them here, I would direct you to the smb.conf man page, available here in html format:
http://us3.samba.org/samba/docs/man/manpages-3/smb.conf.5.html Search for "ACL" and "permission" and "ye shall find". (You can start with "nt acl support = yes".) -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
