Login user programatically in BBPress

Question

I am trying to log in a user programmatically in bbpress, I tried logging the user in in wordpress with the following code snippet:

$username = "Carlos";
$user = get_user_by('login', $username );
$user_id = $user->ID;

clean_user_cache($user->ID);
wp_clear_auth_cookie();
wp_set_current_user( $user_id, $user->user_login );
wp_set_auth_cookie( $user_id, true, true );
update_user_caches( $user );

This seems to work, when I echo is_user_logged_in() it returns true. But the user is not logged in within the bbpress forum.
