wp_validate_auth_cookie has an error. When hashing for the key
$key = wp_hash($username . $expiration);
WordPress and BBPress do it differently thus nullifying the ability to integrate the cookies of the two.
The problem is that this in bbpress pluggable.php:
$key = wp_hash($username .’|’. $expiration);
should be this:
$key = wp_hash($username . $expiration);
There are a few other places where this needs to be fixed too
