Hi Dylan,
Can't help in any specific fashion except to suggest using ethereal or similar packet inspection app to get the complete stream of the request. Not sure if a web proxy is between you and your IIS which might cause issues. Wal From: [email protected] [mailto:[email protected]] On Behalf Of Dylan Tusler Sent: Thursday, 22 April 2010 4:54 PM To: '[email protected]' Subject: Web service call problem - The HTTP request is unauthorized with client authentication scheme 'Negotiate' We're getting authentication issues with a web service call, and have spent a couple of days struggling to get it to work. We have a C# class that invokes the service as part of a BizTalk process. The code that makes the call runs under the context of a service account and looks like this: try { TasksSoapClient client = new TasksSoapClient(bindingName, endpointAddress); string documentId = client.AddDoc(dclass, metaData, mimeType, rName, folder, contents); return documentId; } catch (Exception ex) { throw new Exception(String.Format("Error calling interface at '{0}' with binding '{1}' for method '{2}' with Retrieval Name = '{3}': {4}", endpointAddress, bindingName, "AddDocumentToFolder", retrievalName, ex.Message), ex); } The error that we are getting is Error calling FileNet interface at '[our web service address]' with binding 'TasksSoap12' for method 'AddDocumentToFolder' with Retrieval Name = 'rc10120.xml': The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate,NTLM'. The BizTalk class has a config file that specifies the binding for TasksSoap12 like this (which was generated using svcutil.exe): <customBinding> <binding name="TasksSoap12"> <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16" messageVersion="Soap12" writeEncoding="utf-8"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> </textMessageEncoding> <httpTransport manualAddressing="false" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Negotiate" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" keepAliveEnabled="true" maxBufferSize="65536" proxyAuthenticationScheme="Negotiate" realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false" useDefaultWebProxy="true" /> </binding> </customBinding> Can anyone give me some pointers as to what we could try out here? Ideally we'd like to specify a login name and password for the web service to execute under, or let it run under our service account. I've tried messing with client.ClientCredentials.UserName.UserName and Password, but the results are the same. I guess the first step is to get rid of the above error message, but I guess I don't really understand the error message, and Dr Google (who has been extensively consulted) hasn't been much help either. We are not in a position to change the IIS settings on the web service side, but otherwise we can do quite a bit.
