I've setup a relying party trust to in my prod ADFS server to my lab environment, as I would like to test successful authentication through our Lab domain. I am able to reach the https://
x URL, but need to know how to configure in the lab environment to accept the credentials from our prod environment. I'm assuming it's just a matter of configuring the appropriate claim rules on each end, so in the this case, i would just like to use the UPN in order to authenticate. A walktrough or step by step of how to configure this would be greatly appreciated.
