My take. I'm always a bit oversuspicious when umbrella words are thrown
around.

A certificate is (usually) a signed public key. You need it whenever
you need more complex key management (definitely not when things are
between your server and you).

We are using that schema in our (small) company, too. Private keys
are definitely private here (we don't "issue keys" to anyone, everyone
uploads their *public* keys to the LDAP).

Definitely. "Issuing keys" to people is a "crypto smell". I know,
it is being done far too often. People are too stupid to make their
key pairs, it is often said. But keeping people stupid is your
biggest security hole!
