I have been trying to enroll my company's mobile phones ESMC using the MDC but i can not get the APN certificate through Apple's Push Certificate Portal. When i try to upload my Certificate Sign Request Export i get "Certificate Signature Verification failed because the signing certificate is expired". None of my certificates are expired though. I tried creating the authority certificate and peer certificate for the MDC again and again making sure i input all info in every field and ensuring that the validation period is correct but i still cannot get it to work. Bare in mind that i have only been using ESMC for less than a year so i cannot imagine why any of my certificates will be expired.
Any input will be appreciated. Thank you i advance
