phpBB3Auth - help migrating passwords from phpBB3

[volantis]

I setup the phpBB3Auth mod trying to migrate our forum and haven't had any luck getting the passwords to sync. Here's a link to the mod:

For a long while I kept getting "Unable to connect to DB:" as an error when trying to login. I finally changed the include line that points to controller.php to:

include('/phpBB3Auth/controller.php');

and the error is gone but test users aren't able to login with their existing account and the PWD_Synced in phpbb_users doesn't show any users with value 1.

./phpBB3Auth/controller.php, full-server-path/phpBB3Auth/controller.php, and some other combinations to no avail.

Any ideas?
