WCF中的'System.ServiceModel.Security.MessageSecurityException'

Question

I have WCF client with the following config.

 <system.serviceModel> <bindings> <basicHttpBinding> <binding name="MyService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Windows" /> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://myservername/MyGreatServices/MyService.svc" binding="basicHttpBinding" bindingConfiguration="MyService" contract="XXX.Ixxx" name="MyService" /> </client> </system.serviceModel> 

but when trying to run application getting an error:

An exception of type 'System.ServiceModel.Security.MessageSecurityException' occurred in mscorlib.dll but was not handled in user code Additional information: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate oXoweKADCgEBonEEb2BtBgkqhkiG9xIBAgIDAH5eMFygAwIBBaEDAgEepBEYDzIwMTYwMTEyMjAwNDAwWqUFAgMH13imAwIBKakUGxJVUy5LV09STEQuS1BNRy5DT02qGzAZoAMCAQGhEjAQGw51c21kY2tkYXAxMDg3JA=='.
