azure-ad-b2c - Azure B2C - 提供的令牌不包含有效的颁发者

问题描述

我正在使用 Azure B2C 连接到外部 OpenID Connect 身份提供程序，我在 B2C 中创建了一个基本用户流，它可以工作但只带回少量声明，因此我需要创建一个自定义策略来将自定义输入参数传递给我的IDP 并收集额外的索赔。

我从 SocialAndLocalAccount 示例开始，并使用 IDP 的详细信息进行了修改：

当我单击“B2C_1A_signin_signup_oidc”并选择“运行用户流程”时，我会看到我的 IDP 的登录屏幕，一旦我成功登录，我就会从我的 IDP 获得授权码响应，我的 IDP 已按照“/authresp”重定向 uri 进行了配置Microsoft 文档（底部的“重定向 Uri”部分），但似乎“/authresp”没有将代码交换为 id_token，因为当它重定向到 jwt.ms 时，我得到“令牌不包含有效的颁发者” .

Fiddler 代码响应

通过使用提琴手的检查员，我可以看到 IDP 的端点正在响应一个看起来像这样的代码（不是实际代码）：

<HTML>

<HEAD>
    <TITLE>OIDC Form_Post Response</TITLE>
</HEAD>

<BODY Onload="document.forms[0].submit()">
    <FORM METHOD="POST" ACTION="https://itpauthdev.b2clogin.com/itpauthdev.onmicrosoft.com/oauth2/authresp"> <INPUT

        <INPUT TYPE="HIDDEN" NAME="state"

            <INPUT name="continue" TYPE="SUBMIT" VALUE="CONTINUE" />
        </NOSCRIPT> </FORM>
</BODY>

</HTML>

Fiddler AuthResp 响应

再次使用 Fiddler，我可以看到 AuthResp 没有使用 IDP 的令牌端点交换 id_token 的代码（或遇到错误，我没有得到任何有用的信息）。相反，我回来了：

<html>

<head>
    <title>Object moved</title>
</head>

<body>
    <h2>Object moved to <a
            href="https://jwt.ms/#error=invalid_request&amp;error_description=AADB2C90238%3a+The+provided+token+does+not+contain+a+valid+issuer.+Please+provide+another+token+and+try+again.%0d%0aCorrelation+ID%3a+2ad979b5-384f-43bf-8d05-2230f17553bc%0d%0aTimestamp%3a+2021-02-26+04%3a29%3a08Z%0d%0a">here</a>.
    </h2>
</body>

</html>

问题

  1. 我在某处的文档中读到“OpenIDConnect”技术配置文件将自动交换 id 令牌的代码，但我似乎无法找到该文档，是我的配置缺少步骤还是我必须通过额外的 userjourney 手动执行此操作?
  2. 如果“/authresp”和令牌端点之间存在通信错误，我是否可以在某个地方获得更具描述性的错误消息？jwt.ms 和审计日志都只是说“令牌不包含有效的颁发者”。

JWT错误

标签： azure-ad-b2cazure-ad-b2c-custom-policyidentity-experience-framework

解决方案

该错误意味着来自 OIDC 提供程序的 id 令牌具有与众所周知的 OIDC 配置端点中的颁发者不匹配的颁发者 (iss) 声明。您可以将 issuer 元素添加到 TUO-OpenIdConnect 技术配置文件的元数据中，以使用令牌中显示的值覆盖它。

https://docs.microsoft.com/en-us/azure/active-directory-b2c/openid-connect-technical-profile#metadata

issuer ：OpenID Connect 身份提供者的唯一标识符。颁发者元数据的值优先于 OpenID 知名配置端点中指定的颁发者。如果指定，Azure AD B2C 会检查身份提供者返回的令牌中的 iss 声明是否等于颁发者元数据中指定的声明。
