login to non VB pages, restrict by user

[arossphoto]

I'm thinking about switching my forums from Ikonboard to vBulletin, but I'm trying to find out if there are any hacks or extensions that will allow me to integrate the forums with a php/mysql member database that I have created.

I've seen a few extensions here such as "Simple vB User login and access control on non vB pages" that let you restrict access based on user group, etc, but I want to restrict access to specific users.

What I'm trying to do is allow users to login and edit their details in our member directory based on their forum username and password. It's very important that they only be able to access their record in the database, so I think it would have to based on user id or something similar. I only provide listings to members who make a donation to support our site and who are designated as "supporting members", so not all members will have access.

Right now I have to edit all the listings myself, because I can't figure out how to restrict access without copying every username and password to the contact table in my database. Obviously, that would create an administrative nightmare and I don't want to do that.

Any suggestions or advice would be much appreciated.

Thanks,

Andrew
