IdentityServer4 资源所有者密码和 Win 身份验证：未授权

Question

在过去的几天里，我一直在阅读 IdentityServer4 文档并使用资源所有者密码将我的示例服务器 + 示例客户端放在一起。现在我想并行添加 Windows 身份验证（将通过 Active Directory 完成），因此客户端应用程序（不是网络应用程序而是桌面应用程序）可以提示用户输入凭据或使用 Windows 通过 Active Directory 进行身份验证。

关于 Windows 身份验证的文档解释了如何配置 IIS 或 HTTP.Sys，但我想要的是：

用户打开应用程序
应用程序使用单点登录 post 网络请求 api 请求令牌和刷新令牌
网络 api 使用 windows 身份验证来验证用户身份和 returns 令牌

我已尝试遵循此 answer，但它不起作用（它 returns 未经授权）。

Answer 1

我找到了一个解决方案：我需要用 SubjectId = MYDOMAIN\myusername 配置一个 TestUser 然后它起作用了。

出现的错误过于混乱。
