An Alternative to the Jamf Intune Integration (No more jamfAAD pop-ups)

[bwoods]

If any of you are tired of your users receiving jamfAAD pop-ups, I would highly recommend transitioning to device identification using certificates. This method of conditional access allows you to control conditional access directly from your Jamf Pro server. Access is simply determined by the presence of your certificate. (This does require your users to have E5 licenses)

The certificate is deployed via configuration profile...so no more manual registration either. Perfect for zero-touch deployments. To stop the pop-ups unload or delete any launchAgents related to the jamfAAD Agent. 

You can read more about this process here.

This is definitely worth looking into. I wonder if an MS Defender for Office Plan 1 or Enterprise Mobility + Security E3 license is enough. Picking up E5's for everyone is definitely not cheap.

Hi @Levi_ , I've got more useful information on Microsoft Cloud App Security here.

Will look into this, thanks bwoods. We're already at that license with Defender deployed.

@bwoods - Thanks for the Tip. We have been getting a lot of user complaints since rolling out Intune Integration. I would love to make those go away. 

I have few question:

• When you are deploying the Config Profile to install the certificate are you installing at the Computer level or User level?
• Are you enabling "Allow all apps access" for the certificate?
• Are there any special information needed in the Certificate Subject or Subject Alternative Name?

[bwoods]

@TimArnold. I found that system and user certs work for macOS. I would recommend using a system cert. If your have ADCS or SCEP configured for Wireless you don't even need to deploy a cert. Just upload the Root and Intermediate cert of your ADCS/SCEP cert and the policy will use the PKI cert for conditional access.

I do have "All all apps access" enabled for the certificate.

My San is the same as my wireless cert because my wireless cert and conditional access cert are one in the same. (Let me know if this doesn't make sense.)

This looks real cool.  Going to add this to the POC we are doing.

Is there any documentation to create requirements to get the cert from the config policy?  The link shows how to setup a CA policy in Azure that requires the presence of the cert to get access, but I do not see where we can leverage Jamf in a way that would only pass those certs to machines we deem compliant.  I suppose Smart groups would be the best solution?
