Disconnect federation from a domain in Apple School Manager
If you no longer plan to use federated authentication with a domain, you can disconnect the domain. This process does not affect the domain verification.
Note: You cannot disconnect from a federated domain if Apple School Manager is in the process of enabling federation or is within the 60 day Apple ID conflict resolution period.
