Forums script that coud be bridged with asp.net membership table?

Greetings.


I would like to install into my website that has membership authenitcation and another script, actually forum script like "PHPBB", but is there any way to brdige
the 2 tables (asp.net table with the phpbb) so whoever is an existing site member could have full access and functionality into the forums aswell? If not can you reccomend me a forum script that would work a similar way?


thank you.
