Question

使用带有WebListener

的ASP.net Core 1.1自托管应用的Windows身份

var host = new WebHostBuilder()
                .UseWebListener(options =>
                {
                    options.ListenerSettings.Authentication.Schemes = AuthenticationSchemes.Negotiate | AuthenticationSchemes.NTLM;
                    options.ListenerSettings.Authentication.AllowAnonymous = true;
                })

有时我会收到错误

发生了未处理的异常：已关闭安全句柄

在'User.IsInRole(group)'或'User.Identity.Name'这样的方法和应用程序崩溃这个愚蠢的方法

string userName;
try
{
    userName = User.Identity.Name;
}
catch
{
    userName = "undefined";
}
return userName;

堆栈跟踪看起来像这样：

无法在调试时重现它，但在生产中每周都会崩溃一次。

有什么建议吗？

Interop.mincore.LsaLookupSids已关闭安全句柄
