SM Enrollment Authentication DEP Restrictions with iOS/macOS

[DatITguy]

Is there a reason as to why iOS and macOS devices enrolling through DEP currently do not support enrolling with Azure AD, OpenID, and Google Oauth enrollment authentication? ( https://documentation.meraki.com/SM/Device_Enrollment/SM_Enrollment_Authentication ). Is this a restriction in place by Apple or is it just not developed with Meraki? Just looking for an explanation to better support or users. Appears to be supported on other MDMs, but still unclear.

I don't know the answer.

These enrollment types require the host to be able to "pop" a web browser and present the provider's login page.  I'm guessing this early on in the process Apple devices won't allow that.

@PhilipDAth do you think this would be possible with sync capability with ABM if it was supported? I see this as a possible solution with ASM as accounts are able to be pulled over from that as owners is Meraki. If ABM was a feature of Meraki, the SCIM or federated accounts it could pull from likely would allow this. Do you know if a sync with ABM for users is a feature on a road map? Am I understanding this incorrectly?
