Problem: When attempting to authenticate the parent, the authentication may fail with the error that the “Organization is lacking a service principal”.
Steps to Resolution
This error means that you have multi-tenant inspection enabled on a parent that does not have the Microsoft Partner Center service principle
Disable the toggle for "multi-tenant", then attempt to sign in again.
Outcome: Once this is disabled, you should be able to authenticate successfully
