我创建了一个简单的 Web 服务，并在 Web 服务中编写了一个简单的方法，如下面的代码所示。

    [PrincipalPermission(SecurityAction.Demand, Role = @"KIANCOORP\SomethingElse Users U")]
public string HelloWorld()
{
    var msg = "Hello {0} from internal.".FormatWith(IdentityName);

    _log.Info(msg);

    return msg;
}

我在设置为域用户 KIANCOORP\webapppooluser 的应用程序池中托管了 Web 服务，并且我已将此用户添加到“KIANCOORP\SomethingElse Users U”组中（通过活动目录）。

现在，当我使用 Internet 浏览器浏览到 Web 服务时，我收到以下提示，因此我尝试使用我用来设置为我的这个 HelloWorld Web 服务的应用程序池用户的同一用户登录。

现在，如果我尝试使用正确的凭据登录，则会再次出现提示

就像我必须输入凭据 3 次一样，我已经对此进行了测试，每次我收到登录对话框的提示时，我都必须尝试 3 次，最终它会进入以下浏览器屏幕。

我在网上找不到任何可以帮助我解决此错误的有用信息。

我已经解决了这个问题，这是一个非常奇怪的问题。我在活动目录中查找相同的用户组，我使用 IIS 日志中的用户组字符串文字在活动目录中搜索相同的匹配组，但我找不到它。

Role="KIANCOORP\SomethingElse 用户 U"/>

但是当我浏览活动目录以获取匹配的用户组时，我找到了它，因此我将 IIS 日志中的用户组字符串文字复制并粘贴到活动目录中的用户组名称文本框中，然后单击应用。

然后我重新启动 IIS 并使用 Internet Explorer 再次浏览到 Web 服务，现在 IIS 能够解析我用来登录的用户的访问权限并将其匹配到适当的用户组（如我的 C# 中所写代码“[PrincipalPermission(SecurityAction.Demand, Role = @"KIANCOORP\SomethingElse Users U")]”)，我能够得到一个糟糕的世界响应。
