Yes. I assure you this was not the behaviour of Erlang when I wrote the
SSL guide. Unfortunately, a fix is not going to happen in time for the
next release, but we're going to chase the Erlang SSL module authors to
see if there's any reason for this behaviour, and I hope will change it
either in their code or ours. I agree with you that with verify_peer on,
the broker *must not* blindly trust *any* certs without being able to
establish a chain of trust to the presented cert.
