I'm trying to verify compatibility between some MDM and SAML IdP, and I've faced a problem using device certificates with Intune Portal App for iOS.

 

At Windows, macOS, and Android, device certificates installed each device work at SAML IdP authentication process for adding devices to Intune MDM registration. However, at iOS, it does not work.

 

In the Intune documentation, device certificates troubleshoot is available below. But, iOS one is not.

 

https://docs.microsoft.com/en-us/intune/troubleshoot-device-enrollment-in-intune#android-certificate...

 

It is not about ADFS and its certificate based authentication. And, at other MDM, it works with the same setting.

 

How can I ident whether it is only setting problem or application specification?

 

Regards,
