bbPress.org

I have a WP/bbPress install that uses a custom WP plugin based on http://wordpress.org/extend/plugins/external-database-authentication/ to auth against our external account system.

This works perfectly well for WP, where the plugin will trigger on WP login. However, I don’t want my bbPress users to have to log into WP first in order to access the forums. Ideally, bbPress could use the same plugin (or follow the same logic) to externally auth and create the shared WP account if needed.

Is there a quick way to repurpose or simply invoke the WP plugin from bbPress? If not, can I hook the bbpress login in the same way as wp (in a “bb_authenticate” action)?
