Как автоматом авторизовать пользователя на сайте, после подтверждения e-mail'a?

$USER->Authorize($UserID);

    switch($arResult["MESSAGE_CODE"]
    {
    case "E02":
        ?><? //User was successfully authorized after confirmation
           
            $USER->Authorize($arResult["USER"]["ID"];
            LocalRedirect("/";

        break;
    case "E03":
        ?><? //User already confirm his registration   

            $USER->Authorize($arResult["USER"]["ID"];
            LocalRedirect("/";

        break;
    case "E06":
        ?><? //Confirmation was successfull
           
            $USER->Authorize($arResult["USER"]["ID"];
            LocalRedirect("/";

        break;
