POIdentity of thread in self hosted WCF service when called from Web Application
text
Body
copied!<p>I have a Windows Service that is self hosting a Wcf service, this Wcf service has a tcpBinding with default settings. The Windows service is running as LocalSystem.</p> <p>The Wcf Service is referenced (default settings) by a Web application that is running in IIS 7.5 integrated pipeline within it's own application pool with its own identity.</p> <p>Both are running on the same machine.</p> <p>All is working fine, except that when in the Wcf Service when I check the identity of the current thread with:</p> <p>Thread.CurrentPrincipal.Identity.Name</p> <p>It returns the user of the Application Pool of the Web Application.. this is not what I expect. It looks like some sort of impersonation is going on in the Wcf service.</p> <p>Is this standard behavior? I can't find any documentation on this. And does it mean that when I try to access a database in the Wcf service i'm introducing a identity hop?</p> <p><strong>Edit</strong>, the config on service side:</p> <pre><code> Type serviceType = typeof(WcfService); host = new ServiceHost(serviceType); Binding tcpBinding = new NetTcpBinding( ); Uri tcpBaseAddress = new Uri("net.tcp://localhost:8001/Test"); host.AddServiceEndpoint(typeof (WcfService), tcpBinding, tcpBaseAddress); host.Open(); </code></pre> <p>On the client side:</p> <pre><code> NetTcpBinding tcpBinding = new NetTcpBinding(SecurityMode.Transport); windowsService = new WindowsService.WcfServiceClient(tcpBinding, new EndpointAddress("net.tcp://localhost:8001/Test")); </code></pre>
