I was able to develop a mdm solution.
I started facing problem when I moved my agent from Developer account's provisioning profile to Enterprise account's in-house distribution profile.
Now I am totally confused which certificate is used where?
Please guide me his is the certificate used in the below places:
Thanks
You need to use your iOS Enterprise developer account use the Agent account's credentials.
Follow this page http://www.softhinker.com/in-the-news/iosmdmvendorcsrsigning and then verify few things as remove the passphrase from customerPrivateKey.pem using this command
openssl rsa -in customerPrivateKey.pem -out PlainKey.pem
Verify the .pem certificate downloaded from https://identity.apple.com/pushcert/
You can install this .pem in you Mac's Keychain and then see the Get Info and the certificate should have com.apple.mgmt.External.b503419d-1e2a-a60f-7451-5b8832b5a9cb, which you can use as push topic while generating enroll mobileconfig .
Then merge your APNS certificate (for example CustomerCompanyName.pem) downloaded from the portal https://identity.apple.com/pushcert/ using this command
cat CustomerCompanyName.pem PlainKey.pem > PlainCert.pem
Now the PlainCert.pem you can use as APNS/MDM certificate.
Please see this for Identity.p12 and respective password, which you have to use in Credential section.
