## Discussion

The schema for a JSON or property list XML document that an MDM server’s 403 response body contains. The response headers need to include a “Content-Type” header that indicates whether the response returns JSON or XML.

The MDM server returns this response when a device enrolls in MDM during Setup Assistant and it requires the user to sign-in using Platform SSO before it allows enrollment and setup to proceed.
