Turn on and test federated authentication in Apple Business Manager
After you’ve completed a successful administrator account sign-in and the username conflict check is complete, you can enable and test federated authentication.
Enable federated authentication
In Apple Business Manager , sign in with an account that has the role of Administrator, Site Manager or People Manager.
Click Settings at the bottom of the sidebar and then click Accounts below Organisation Settings.
Click Edit in the Federated Authentication section and then turn on federated authentication for the domains that have been successfully added to Apple Business Manager.
It may take some time to update all accounts.
Test federated authentication
You can test the federated authentication connection after you’ve performed the following tasks:
You’ve completed a successful connection to your domain.
The username conflict check is complete.
The Managed Apple ID default format is updated.
Note: Accounts with roles of Administrator, Site Manager and People Manager can’t sign in using federated authentication; they can only manage the federation process.
In Apple Business Manager , sign in with an account that doesn’t have a Staff role.
If the username is found, you’ll see a new screen indicating you are signing in with an account in your domain.
Click Continue, enter the password for the user and click Sign In.
Sign out of Apple Business Manager.
