For an experimenting project I’am struggling with a service. The client is an ASP.NET MVC 4 and the service will be build with WCF. For now all the systems are in a trusted subsystem so SSL/certificates is not necessarily.

The problem I’am currently dealing with is: Is het possible when I create a new GenericIdentity like:

IIdentity newIdentity = new GenericIdentity("Test", "Custom authentication");
string[] newRoles = { "TestRole" };
IPrincipal testPrincipal = new GenericPrincipal(newIdentity, newRoles);
Thread.CurrentPrincipal = testPrincipal;

It is possible to have the created user when I’am on the WCF service calling the following code:

ServiceSecurityContext.Current.WindowsIdentity;

Or

ServiceSecurityContext.Current.PrimaryIdentity;

Or

Thread.CurrentPrinicpal;

I get the user which I created in the client? Or do I have to write a WCF extensibility for this?

I’m currently using a WsHttpBinding and security mode Transport and clientCredentialType: Windows. Maybe something wrong about the configuration?

    I discovered to achieve this automatically in WCF that you must specify a certificate…

    In the messages that are sent to the WCF service I created a few properties with the information in the datacontracts that is necessary to create a GenericPrinicpal (in this the username en the roles). Because I have an trusted subsystem I don’t want to authenticate the user on each WCF-service (to much overhead for my scenario). See also Trusted subsystem

    With this I created a WCF extension that implemented a parameter inspector and with reflection I set the credentials from the CurrentPrincipal in the specified properties of the contract. For more information about parameter inspectors and how to apply it
