I have a Silverlight client that has some problems with the server it comes from through WCF basicHttpBinding. The service configuration is as follows:
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="silverlightBinding">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<services>
<service name="MyServices.ImportService">
<endpoint address="" binding="basicHttpBinding"
contract="MyServices.IImportService"
bindingConfiguration="silverlightBinding" />
</service>
</services>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
</system.serviceModel>
A server is an IIS6 web server that is configured to use integrated authentication. The application pool identifier is a domain account.
Now, some calls from the Silverlight client on the web server include the client identifier (the domain user who accesses the client), and some do not! I have included part of the IIS log to show this:
