最近几天，我一直在阅读IdentityServer4文档，并使用资源所有者密码将示例服务器+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Web应用程序，而是桌面应用程序）可以提示用户输入凭据，也可以使用Windows身份验证通过Active Directory登录。
有关Windows身份验证的文档介绍了如何配置IIS或HTTP.Sys，但是我想要做的是：
我已经尝试遵循此answer，但是它不起作用（返回未经授权的内容）。

答案 0 :(得分：0)
我找到了解决方案：我需要使用SubjectId = MYDOMAIN\myusername配置一个TestUser，然后它才能工作。
得到的错误过于混乱。
