How To Pass Integrated Authentication User on to Another Web Service Using WCF Web Api

Question

I have the following setup:

Intranet Application --> Call WCF Web Api --> Calls Autonomy Worksite Web Server

The call to the worksite web server must be from the authenticated active directory user making the call to the intranet application.

So I guess I'm hoping I can pass the credential on to the WCF Web service, which can then use them to make the web service call.

Is this possible? Or should I ask the user to enter his / her password.......

You'd want to configure contrained Kerberos delegation in Active Directory, in order to pass the original callers credentials to the WCF application.
