连接到SSAS时，解析WS-Trust响应失败

Question

我正在尝试在小型Web应用程序中连接到Azure Analysis Services。我在Server as_svr = new Server(); String as_conn_str = "Provider=MSOLAP;Data Source=<Server Name>;Integrated Security=SSPI;Persist Security Info=True;"; as_svr.Connect(as_conn_str); 中提出的代码是：

parsing_wstrust_response_failed: Parsing WS-Trust response failed

使用我的Windows凭据。

不幸的是我一直在：

    [AdalException: parsing_wstrust_response_failed: Parsing WS-Trust response failed]
   Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext.RunAsyncTask(Task`1 task) +89
   Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext.AcquireToken(String resource, String clientId, UserCredential userCredential) +29

   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +35
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1639

更具体地说：

Server as_svr = new Server();
String as_conn_str = "Provider=MSOLAP;Data Source=<Server Name>;User ID=<UserID>;Password=<Password>;Persist Security Info=True; Impersonation Level=Impersonate;";
as_svr.Connect(as_conn_str);

我也尝试过使用：

{{1}}

并产生相同的错误。它必须连接到某些安全设置，但我没有任何相关领域的经验。

如果有任何帮助，我将不胜感激。 谢谢。
