我正在使用AIF Web服务连接到Microsoft Dynamics AX 2009。VS2010中为该服务生成了代理，但当我想使用生成客户端类连接到该服务时，系统似乎没有对我进行身份验证。
我甚至尝试添加域用户/密码并使用Windows身份验证，如下所示：

var binding = new BasicHttpBinding();
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
var address = new EndpointAddress(new Uri("http://dynamicsserver/salesorderservice.svc"));
var client = new SalesOrderServiceClient(binding, address);
client.ClientCredentials.Windows.ClientCredential = new NetworkCredential("admin", "pass", "domain);

默认绑定是HttpBinding，我正在尝试使用控制台应用程序连接到AIF，该应用程序正在同一台计算机上使用NetworkCredential中指定的同一帐户运行。
应用程序连接到Web服务时出现以下错误：

System.ServiceModel.FaultException: You cannot log on to Microsoft Dynamics AX.. Error details: Unable to log on to Microsoft Dynamics AX.. Check the Web server event viewer for more information, or contact your Administrator.
