Windows Integrated Security in WCF Service
===

I have a .Net 4.0 WCF service hosted in a Windows service using Transport Security over a net.tcp binding. There were plenty of good examples of how to set this up. What I am looking for now are examples of authorizing users in this scheme. 

We are assuming that this service will be part of a system that is all on one domain with Active Directory. Is there any advantage to doing claims-based authorization using ADFS rather than Windows Integrated security?

Thanks!
