I try to check the documentation on how to install the code unit on NAV side as well as install DynamicWebConnectorService and DynamicWebServiceTestApp. The code unit successfully installed on NAV but when I try to connect the DW to the web service I got an error saying " The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate'."
I tried using the DynamicWebServiceTestApp it retrieves the data successfully. Both configuration are the same with the test app and the connector service.
