Using Kerberos authentication and impersonation

I'm developing a soluition for a customer that needs to use kerberos authentication for the PWA site instead of NTLM.

This works when having only 'Windows Authentication' enabled in IIS Authentication. I had to Disable ASP .NET Impersonation to get the system to work at all, but now all code using impersonation throws the exception: Unhandled Communication Fault occurred.

I have no experience using kerberos before.

Any help I can get with this issue would be extremly appreciated! :)


The problems I had was related to confiuration issues on the customer's server. No code changes had to be made to make the solution work with Kerberos.
