ASP.NET MVC Windows身份验证拒绝工作
我已经使用Visual Studio 2015创建了一个MVC Web应用程序。我的目标是将身份验证模式从none更改为Windows Authentication，因此我可以使用@ User.Identity.Name方法来标识用户。 以下是我迄今尝试过的简短摘要：
项目属性
Web.config文件
<system.web>标记中添加<authentication mode="Windows"/> 添加system.webServer标记（每当我添加它时，都会以ERR_TOO_MANY_REDIRECTS结尾）：
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxUrl="10999" maxQueryString="2097151" />
</requestFiltering>
</security>
</system.webServer>
视窗
IIS Express
我试图从头开始创建一个新项目，并在项目设置过程中整齐地选择Windows身份验证。 这工作正常，所以我相信我的IISExpress设置是100％正确的 。 我甚至检查了applicationhost.config文件，它没有针对我的特定项目的条目。 再说一次，如果我在创建一个新项目时选择正确的认证，它就可以正常工作。
上面没有一个似乎工作，并且当我尝试运行Visual Studio项目时，所有结果都出现IIS错误：
HTTP Error 404.15 - Not Found
The request filtering module is configured to deny a request where the query string is too long.
这是在IIS错误页面中URL的样子：

正如你可以说我得到一个无限的重定向循环，这可能是我无法得到这个工作的原因。 然而，我不知道是什么导致了它。 任何帮助是极大的赞赏。
猜猜我能够回答我自己的问题，因为我刚刚开始工作。 对于将来遇到类似错误的人可能会派上用场。
解决方案：我必须在App_Start / Startup.Auth.cs中注释以下代码：
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Account/Login")
});
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
您还可以在请求期间检查C： Users [您的用户名] Documents IISExpress Logs [应用程序名称]以获取任何错误详细信息或URL。
