Apple Server Profilemanager - unique certificate advisable?

Dealing with the Apple Server MDM, we have recognized five (possibly different) certificates:

  • services protected by certificate (in common, or separated):
    • open directory protected by certificate (#1),
    • profile manager protected by certificate (#2),
  • apple school manager: identity certificate (#3),
  • device communication: apple push messages (#4),
  • configuration profiles: code signing certificate (#5).

The certificate #4 is available via apple push certificates portal (bound to an Apple-ID). All others can be retrieved by a generic CA - not really related to an Apple-ID.

In fact, the certificate number #2 will be visible on the Web UI and should be matching the official hostname.

What about the other certificates: Any hints how to deal with the four different certificates? Are there any reasons to use distinct certificates ?
