Use CSCART login for Forums?

Is there a addon, bridge, or other script that allows the use of the CSCART credintials to be used for a forum that is installed on the same site.



I want to install IP.Board or VBulleiten (etc.) but i dont want to have the customer/user to have to create another account for the same site.



Anyhelp in the right direction would be appreciated. Dont want to have to start writing one myself if someone has already gone through the work.

OKÔÇŽill talk that as no. Im going to write it for PHPBB 1st then since i can get a copy of that for free. If anyone has IP.Board or Vbulletien ill make a bridge for those as well.
