来自UserInterface类

interface UserInterface {
    /**
     * The equality comparison should neither be done by referential equality
     * nor by comparing identities (i.e. getId() === getId()).
     *
     * However, you do not need to compare every attribute, but only those that
     * are relevant for assessing whether re-authentication is required.
     *
     * @param UserInterface $user
     * @return Boolean
     */
    function equals(UserInterface $user);
}

我应该如何实现这一点(" 那些与评估是否需要重新认证相关的那些 ")？那么这是否意味着它在Symfony 2重新认证(用户名/密码)后用户？或者是此功能用户重新进行身份验证.我可以查一下id, username, password, salt吗？Symfony不通过密码检查重新验证用户,这应该足够了吗？
