FreeRADIUS Rest 身份验证更新失败

FreeRADIUS Rest auth failing on update

我遇到了类似的问题 。就我而言,我正在尝试在 API 方面执行所有逻辑。 API 看起来不错,拒绝无效用户已经可以正常工作了。问题是使用从 API 返回的属性进行身份验证。 FreeRADIUS 的 rest 模块在意识到响应 returns 某些属性并且无法通过身份验证后发出更新命令。

我的配置如下所示:

authorize {
rest
    if (ok) {
        update control {
            Auth-Type := rest
        }
    }
}

逻辑是:如果用户退出(APi 响应状态代码 204),则签入授权,然后执行身份验证。身份验证将用户名和密码发送到 API。 API 检查一些信息,然后 returns 使用状态代码 200 和正确 JSON 格式的属性(如果一切正常)。

奇怪的是,如果我将 API 设置为使用状态代码 204 而不是 200 进行响应,用户将正常通过身份验证(但没有任何属性)

提前感谢您的任何提示。

是的,我想我在 v4.0.x 中修复了这个问题。这是一些遗留问题 'updated' 不是可接受的 return 代码。

您可以使用以下代码覆盖 return 代码和优先级:

authenticate {
    Auth-Type rest {
        rest {
            updated = 1
        }
        if (updated) {
            ok
        }
    }
}

解释 - 每个 return 代码 'ok'、'noop'、'fail' 等...根据部分具有不同的优先级和操作。如果模块的 return 代码具有更高的优先级,则只更新第 return 部分代码。

有一个神奇的优先级 'return' 会导致服务器立即退出该部分。它是为验证部分中的大多数 return 代码设置的。

我们需要覆盖调用 rest 模块的优先级,因此解释器不会 return 在不评估条件 if (updated) 的情况下进行身份验证。在上面的例子中我们将更新的优先级设置为1,保证以后可以覆盖。
