I came across this in a thread.
https://wordpress.org/support/topic/not-working-for-bbpress-rolesWould that be somehow useful? Probably not.

/**
 * FORUM - Role map
 * bbPress has its own internal ("dynamic") Roles, so we map our real wp roles to bbPress.
 */
add_filter('bbp_get_user_role_map','my_bbPress_role_map');
function my_bbPress_role_map($role_map){
	$role_map['student'] = bbp_get_participant_role();
	return $role_map;
}
