There's a reasonable overview here:
https://hea-www.harvard.edu/~fine/Tech/ssh-host-based.html
Basically it's to get rssh-like functionality between a local cluster of
machines that trust each other. A user logged in as "foo" on machine A
can ssh into account "foo" on machine B. But instead of user foo having
their own personal key pair, there's a key pair between the hosts
themselves.
That's how we use it in our HPC cluster. We don't use it anywhere else
due to security concerns.
