This project is not covered by Drupal’s security advisory policy.

Allows Drupal to manage user accounts for UBB and provide single sign-on. Also includes a simple importer/exporter for copying existing user accounts between UBB and Drupal.

This module is intended to serve as a bridge for UBB sites to integrate with, or begin migrating to, Drupal. With this module, you can:

  • Import your existing UBB users into Drupal.
  • Export your existing Drupal users to UBB.
  • Create a matching UBB account when a new Drupal user registers.
  • Update UBB when a user changes their name, e-mail address or password.
  • Log a user in/out of UBB when they log in/out of Drupal (by setting a cookie).


  • UBB 7.5.4.x. Other versions may work, but have not been tested.
  • Your Drupal instance MUST be able to access your UBB database (obviously).
  • The single sign-on feature will only work if Drupal and UBB share the same domain name. It will not work cross-domain or with subdomains (if you're not sure what that means, see the table below). This is a result of the way UBB handles the login cookie and cannot be changed.
    If Drupal is at... and UBB is at... then single sign-on is...
    Same domain
    Cross-domain Not supported
    Subdomain Not supported


Development of this module was sponsored by Christians in Recovery (6.x-1.x and 7.x-1.x branches) and MacTech (6.x-1.x branch only).


This module is only minimally maintained, due to a lack of community interest. Apparently, the module's sponsors are the only people in the Drupal community using UBB. :)
