you need a specific ad permission to register an SPN (unless you are a domain 
admin)

What should I do about the SPN? It won't let me register a SPN with the service 
account for some reason. Is that to be expected? Should I ever care?

in a LAB, yes you can run ADFS on your DC.  it will install and it will 
function.

But, PLEASE don’t do that in prod.

Before anyone tells me that I am not supposed to run anything else on a domain 
controller… This is a SMALL LAB ENVIRONMENT  and my resources are limited….

Is it, from a technical perspective, possible to add the ADFS role onto a 
domain controller? When I try to set the SPN I get a message "Duplicate SPN 
found, aborting operation!"  Just for grins I also tried to set the SPN for my 
CM server and I get the same message.
