APNS MDM Push Notification Topic - Where to find?

Question

I searched everywhere for the topic of push notifications to send in my MDM registration profile, and I looked at the information on my developer's / distribution topic, but cannot find anything like this:

b503419d-1e2a-a60f-7451-5b8832b5a9cb 

What am I missing?

Answer 1

As Michael Guffney says:

The subject is the UID value in the subject of your APN certificate. This will start with com.apple.mgmt.

To get it:
1. Go to https://identity.apple.com/pushcert/ and download the certificate
2. Get the topic from the certificate using OpenSSL, for example,
bash-4.2.45$ openssl x509 -noout -in MDM_ \ABC \,LTD_Certificate.pem -subject
Gives this result:
subject= /UID=com.apple.mgmt.External.9a68c111-109a-9084-a9f7-fffffffffff2/CN=APSP:9a68c111-109a-9084-a9f7-fffffffffff2/C=PE

The notification subject in this case is com.apple.mgmt.External.9a68c111-109a-9084-a9f7-fffffffffff2

Answer 2

The subject is the UID value in the subject of your APN certificate. It will start with com.apple.mgmt.
