I wonder whether you have an answer to my question below.
Currently my organization is sharing a dynamics CRM 365 instance (cloud) with another org, each org has its own dynamics portal, but both portals use one b2c azure active directory for portal user authentication, this has caused issue for both orgs, as the user from one portal can login to another portal without authentication.
Now we want a separate instance for each org. We have copied the current CRM instance (UAT) to a new sandbox instance for test.
My question is that: Can we make a copy of the current B2C azure directory and have it used by the new instance so a portal user can use his existing credential to login to the new portal? Any help is much appreciated!
