Yes, they are a requirement for FQDNs and for Mac OS X.
Which does not mean they have to be created on the same server.

Yes it should.
No. If you don't own the IP address range - like, say, the OP -
you're not authoritative for the reverse lookups, and therefore not
supposed to create the PTR records. Of course one should make sure
the records exist (i.e. have the owner of the address range create
them), but that's a different story.
This misses the point of FQDNs and DNS and Mac OS X.
YOU don't have to be authoritative for the CIDR block to be able to
provide the PTR that OS X requires. YOU just have to be able to
provide the information. YOU do not to provide this information to
OTHERS.
That is you can have split horizons.
M-hm. I can have split DNS in Server Admin (which is - need I remind
you - what the OP wanted to use)? Pray tell how do I configure split
DNS in OS X without manually editing the DNS config?
It's not a afunction of how you define them, it's a function of how
you use them.
> So: "Yes, it should" or more accurately "Yes, YOU should" have PTRs
for ALL of your hosts that OS X needs to reference. Otherwise you
dont' have FQDNs.
I MUST create PTR records regardless of whether I'm authoritative for
the address range and regardless of whether the authoritative DNS
already provides the PTR records?
You are automatically authoritative for any RFC1918 addresses.
So in a situation where I'm not
authoritative I MUST manually configure split DNS instead of just using
the PTR records provided by the authoritative DNS? o_O
*Please* tell me OS X isn't THAT broken.
No, it's not the way you describe at all.
If you don't own the IP addresses you're using then you are already
not authoritative for your address space.
Instead use split horizons for your systems and let the world use a
different view or server.
Just works like it should.
