I can't seem to make public key authentication work for connecting to a
VMS box running Multinet 5.1A from a unix (MacOS X) box.

On the unix box I have a 2048-bit RSA public key id_rsa.pub in open-ssh
format. I use this key with success on various unix systems.

I used ssh-keygen to export a copy in the format used by VMS; the result
looks like this:
---- BEGIN SSH2 PUBLIC KEY ----
Comment: "2048-bit RSA, converted from OpenSSH by rowen@..."
AAAAB3NzaC1yc2EAAAABIwAAAQEAyTIpI6IxXiv9/UIs/opZ5vPk9CnPCz+p5QwoqD1Klh
...
---- END SSH2 PUBLIC KEY ----

Then I saved that copy to the VMS account as [.SSH2]ID_RSA.PUB
and created [.SSH2]AUTHORIZATION. which contains just the text
"ID_RSA.PUB"

The [.SSH2] dir looks like:
AUTHORIZATION.;1 (RWED,RWED,RWED,RE)
ID_RSA.PUB;1 (R,R,R,R)
RANDOM_SEED.;1 (RWD,RWD,,)

but authentication fails. Any ideas? I've appended a maximally verbose
log (which is rather long).

You need the keyword KEY in front of the filename, like
"KEY ID_RSA.PUB".

Haven't looked at the log - first fix your AUTHORIZATION file.

Oops. That did it. Thank you!
