Liferay integration with OpenSSO

I read this blog from Prashant. a few days ago about integration with Liferay and OpenSSO.

We just integrated the code snippets into Liferay so users can easily integrate with OpenSSO by just going to the Enterprise Admin portlet and entering the right settings. No more code or properties changes.

what is the "right settings"? a few people can't seem to get this code working right. doesn't create the session variable to create the liferay user or get the liferay user info. seems the opensso autologin filter never runs for some reason.
