How to have dual login with WordPress and PHPBB??

I’ve been looking into how to integrate wordpress and phpbb for ages, i just haven’t been able to do it.
I think this is the best solution, does anyone know a plugin that can do this?

I’ve come accross this site and it does it quite well.. blinkdisasters.com
Thanks for your help

edit: would http://wordpress.org/extend/plugins/phpbb-single-sign-on/ do this??
