Meraki SM supports SAML-based authentication (e.g., Okta, Azure AD, OneLogin) for device enrollment. This can be used to authenticate users during the ADE process if configured properly.
Note: If enrollment authentication settings change, iOS and macOS devices enrolling through ADE (formerly DEP) may encounter enrollment issues. Resolve ADE enrollment issues by creating a new ADE payload ensuring the "Use network's user authentication" value is set correctly.

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
