IPBWI equivalent?

I've been out of the web site game for a while, but coming back I chose to start with a Xenforo forum. I'm currently looking for an addon that would provide me the same features I was able to get from using IPB/IPBWI, any suggestions?
The ability to use my forum as content and news as well as the single sign on for password protected pages. Forum guest/member statistics isn't so much a necessity.
