title: Multiple APNS certificates in same certificate file
body: <p>I've been searching for an answer to this and can't seem to find it. I send PUSH notifications to multiple flavors of my apps.  I have previously set this up to loop through each certificate and match it against the users app type.  Effectively I create a new SSL connection for each certificate and then send any notifications for that particular certificate.  </p>
  
  <p>It's a bit tedious to convert all of these certificates and install them when they expire.  I can export multiple certs from KeyChain access as a single p12 file and convert it which helps keep things simpler from a certificate management standpoint. The problem comes in that none of my PUSH notifications are being received.  I can connect to the APNS successfully and no problems are reported by the feedback service yet nothing seems to go through.  This leads me to believe that the APNS is verifying the only the first certificate in the file and ignoring any others which would allow for a successful connection but would likely prevent delivery of the notifications.  In this case I would expect a dropped connection or something reported on the feedback service though and so far I've seen neither.</p>
  
  <p>Does anyone have any insight into doing this successfully?  Thank you.</p>
