I recently worked with the folks that handle the virtual labs for Technet. We corrected the certificate issues and some other minor issues. You can access the lab here.
After completing this lab, you will be better able to set-up a trust relationship among business partners. You will walk-through creating, populating, and transforming "claims" about users that are shared between security contexts. Additionally, you will turn federation claims into authorization decisions in a federated application and finally, you will integrate a claims-aware application.
This is a very cool way to get your hands on ADFS without having to setup 3 or 4 virtual machines.
