Users from larger organizations who have enrolled in Federated Authentication are unable to log in to Xcodes using their Apple IDs. This issue primarily affects users whose Apple IDs are managed under their company's Business Manager, requiring authentication through an identity provider.

Users with Apple IDs under Federated Authentication cannot log in to Xcodes. They receive the error message:

unexpectedSignInResponse(statusCode: 403, message: Optional("-22320: Federated Authentication is required."))

The implementation of a Federated Authentication flow is essential for users who rely on corporate-managed Apple IDs.
