Hi,

I am trying to connect to a web service served by SAP and i have authentication problem.

I simply added the service by right clicking project, selecting add service reference, giving WSDL url for the service and clicking OK.(After clicking ok asked for credentials and i provided them)

Then when i tried to call a method from the serviceclien object i got the error message below:

The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The
authentication header received from the server was 'Basic realm="SAP Web Application 
Server <hostname>"'.

Web Config Related Part:

<basicHttpBinding>

 <security mode="None">       
  <transport clientCredentialType="None" proxyCredentialType="None"
   realm="">
   <extendedProtectionPolicy policyEnforcement="Never" />
  </transport>       
  <message clientCredentialType="UserName" algorithmSuite="Default" />
 </security>
</binding>

Also, What problems will i face with? I do not want to use SAP .NET Connector. Thanks...
