Hi.

I'm having a problem with my Drupal and my forum (IPB).
In my forum i have 30.000 account users, and i would work this accounts in the Drupal (in the drupal's databse dont have any account [only de admin account]).

Example:
One guest make a account in the forum, and this account work in the Drupal.
One guest make a account in the Drupal, and this account work in the Forum (IPB).

Is this possible?
The two system use the same database, i don't know...

Can anyone help me?
Thanks
