WCF - netTcpBinding with clientCredentialType="Windows" - Across Domains

I am using netTcpBinding to try and access a WCF service.

  • The ASP.NET web application that is attempting to access the service is hosted on a webserver in a DMZ network.
  • The service is hosted on another server in another domain

I am attempting to connect via clientCredentialType windows.

But when the web application attempts to hit the service I am getting an authentication error. Is it possible to use clientCredentialType="Windows" to access a machine hosting a service on another domain?

Solution

  • No it is not possible because if there is no trust between domains so the machine hosting the service cannot validate credentials of the account running the client on another machine.
