Question

我创建了一个简单的Web服务，在Web服务中，我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;
}

我已将网络服务托管在设置为域用户KIANCOORP \ webapppooluser的应用程序池中，并且我已将此用户添加到＆＃34; KIANCOORP \ SomethingElse用户U＆＃34; （通过活动目录）。

现在当我使用互联网浏览器浏览到Web服务时，我得到以下提示，所以我尝试使用我曾经设置为我的HelloWorld Web服务的app pool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

就像我必须输入凭证3次一样，我已经测试了这个，每次我都会通过登录对话框提示我必须尝试3次，最后它会进入以下浏览器屏幕。

我无法在网上找到任何可以帮助我解决此错误的问题。

Answer 1

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了相同的用户组，我使用IIS日志中的用户组字符串文字在Active Directory中搜索相同的匹配组，但我无法找到它。

Role =“KIANCOORP \ SomethingElse Users U”/＆amp; gt;

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，因此我将用户组字符串文字从我的IIS日志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相应的适当用户组（如在我的C＃代码“[PrincipalPermission（SecurityAction.Demand，Role = @”KIANCOORP \ SomethingElse Users U“）]”）中，我能够得到一个hellow world响应。

IIS WebService主体权限请求失败
