WordPress MU

Hi there!

I am trying to make wordpress mu using the vbulletin's user database, but so far without success.

I just want that you can login with the vbulletin user data, there is no registration required, just the login feature.

My wordpress mu and vbulletin are installed in the same database. So what I need to do is to copy the tables of 'wp_users' to 'vb_user' and make the login script using salted logins by the 'salt' table at 'vb_users'

The vBulletin encryption goes so on:
<?php
md5(md5($UNENCRYPTED_PASS).$SALT)
?>

Does somebody know how i have to do that?
I'm tankful for every tip.

Best regards
Marc

I don't have a link handy but I do know a vbulliten -> wordpress bridge exists. It gets discussed over on the wp.org forums on occasion.

any luck on this?

I'd like to bridge WPMU and vBulletin
