错误发现了SecurityNegotiationException

对SSPI的调用失败，请参阅内部异常。

通过来自visual studio 2010的电话ledgerservice将ax 2012整合到c＃应用程序中 并成功调用该服务 这是代码：

try
    {
  NetTcpBinding binding = new NetTcpBinding();
    binding.Security.Mode = SecurityMode.Message;
   // binding.OpenTimeout = new TimeSpan(0,10,0);
   // binding.ReceiveTimeout = new TimeSpan(0, 10, 0);
   //// binding.SendTimeout = new TimeSpan(0, 10, 0);
   // binding.CloseTimeout = new TimeSpan(0, 10, 0);
    //EndpointAddress address = new EndpointAddress("net.tcp://apserver:8201/DynamicsAx/Services/LedgerServices");


    GeneralJournalServiceClient client = new GeneralJournalServiceClient();
    //binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.None;
    client.ClientCredentials.Windows.AllowedImpersonationLevel =
    System.Security.Principal.TokenImpersonationLevel.Impersonation;
   /* CallContext context = new CallContext();*/

    client.ClientCredentials.Windows.ClientCredential.Domain = "elsedawy";
    client.ClientCredentials.Windows.ClientCredential.UserName = "administrator";
    client.ClientCredentials.Windows.ClientCredential.Password = "P@ssw0rd";


    //context.Company = "sdwy";

    journalLine.AccountType = AxdEnum_LedgerJournalACType.Ledger;

    AxdType_DimensionAttributeValue dimValue3 = new AxdType_DimensionAttributeValue();

    dimValue3.Name = "CostCenter";

    dimValue3.Value = "5637145326";*/


    account.Values = new AxdType_DimensionAttributeValue[1] { dimValue1/*, dimValue2, dimValue3*/ };

    journalLine.LedgerDimension = account;

    journalLine.AmountCurDebit = 120;

    journalLine.AmountCurDebitSpecified = true;

    journalHeader.LedgerJournalTrans = new AxdEntity_LedgerJournalTrans[1] { journalLine };

    journal.LedgerJournalTable = new AxdEntity_LedgerJournalTable[1] { journalHeader };



    client.create(null, journal);
    }

    catch (Exception ex)
    {
        string error = ex.Message;
    }
