These scenarios work in their pieces. Its when i put it all together that it breaks.
I have a WCF service using netTCP that uses impersonation to get the callers ID (role based security will be used at this level)
on top of this is a WCF service using basicHTTP with TransportCredientialOnly which also uses impersonation
I then have a client front end that connects to the basicHttp.
the aim of the game is to return the clients username from the netTCP service at the bottom - so ultimatley i can use role based security here.
each service is on a different machine - and each service works when you remove any calls they make to other services when you run a client for them both locally and remotley. IE the problem only manifests when you jump accross more than one machine boundary.
IE the setup breaks when i connect each part together - but they work fine on their own.
I also specify
[OperationBehavior(Impersonation = ImpersonationOption.Required)] in the method and
have IIS setup to only allow windows authentication (actually i have ananymous enabled still, but disabling makes no difference)
This impersonation works fine in the scenario where i have a netTCP Service on Machine A with a client with a basicHttp service on machine B with a clinet for the basicHttp service also on machine B ... however if i move that client to any machine C i get the following error:
The exception is 'The socket connection was aborted. This could be caused by an error processing your message or a receive
timeout being exceeded by the remote host, or an underlying network resource issue. Local socket
timeout was '00:10:00''
the inner message is 'An existing connection was forcibly closed by the remote host'
Am beginning to think this is more a network issue than config ... but then im grasping at straws ...
the config files are as follows (heading from the client down to the netTCP layer)
