Constraint Delegation with MIT Kerberos

Thanks Christopher.  I have followed this and can get it to work, but when I add MIT Kerberos into the mix it does not work.  According to Microsoft 3 Tier Kerberos support there needs to be a service or spn configured for MIT Kerberos to do Constraint Delegation.  So I am looking for documentation or cook book on how to configure MIT Kerberos to do Constraint Delegation.

I do have Full\Open Delegation working, but one of the servers (Microsoft Power BI Server OnPrem) requires Constraint Delegation.  I have not found instructions for setting Constraint Delegation up in a Windows server environment.  Could someone share the instructions, if they exists or provide me the steps to make this work?
