Perhaps Redhat has to much removed? I have not fonud a better document, but in:
http://docs.oracle.com/cd/E19099-01/nscp.dirsvr416/816-6682-10/oc_dir40.htm
is described the requiered attributes and like on http://github.com/cgrzemba it should work if you add this:

nsslapd-pluginDescription: Sync Posix Attributes for users and groups between AD and DS if available and user lock/unlock
nsslapd-pluginVendor: Redhat
nsslapd-pluginId: posix-winsync-plugin
nsslapd-pluginVersion: POSIX/1.0
