我也在尝试探索 fedlet + adfs federation。
我所拥有的是：
安装在机器 A 上的 adfs 服务器。我还添加了 fedlet 作为依赖部分，但是当我输入回复方联合元数据 url 并单击测试 url 时，它向我抛出了异常： 读取联合元数据时发生错误。验证 url 或主机名是有效的联合元数据端点。 但是我在依赖部分添加了fedlet的证书，并将算法设置为SHA-1。
在机器 B 上完成了 openam 设置。在同一台机器上的 openam 和 tomcat 中添加了 adfs 证书。
使用这个 openam 构建创建了一个 fedlet，并将 adfs 设置为我的托管身份提供程序，它安装在机器 A 上。这个生成的 fedlet 战争也部署在机器 B 上
怎么了：
当我从机器 A 的浏览器访问 fedlet 链接时，它必须在单击第 1 行时进行链接，它会调用 adfs 并要求提供 adfs 登录凭据。
一旦我输入凭据，它会将我重定向回 fedlet 应用程序，但是会引发以下异常：
Http 状态 500 - 响应中的无效状态代码。
如果有人可以帮助我解决此异常，我将不胜感激。
更新：
当我使用 firefox 的 saml tracer 插件解码发送到 fedlet 应用程序的响应时，我得到以下信息：

因此，根据我的理解，异常是由于一些无效的 nameid 策略而出现的。我应该如何解决这个问题？
