Review comment:
I had installed Docker for Mac from [1] a while ago; it's at version
3.3.0. As I discovered today when I tried to run this, that didn't give me
docker-machine. So I installed docker-machine from [2]. At that point, running
the test tried to use a docker-machine "" and failed. So I created a docker
machine (`docker-machine create -d virtualbox default`) and re-ran the test;
and then we are at my original comment from above: connection works only with
sshdContainer.getHost().
As for maven/JDK versions:
```
$mvn --version

> ----------------------------------------------------------------
>
> Key: SSHD-1161
> URL: https://issues.apache.org/jira/browse/SSHD-1161
> Project: MINA SSHD
> Issue Type: New Feature
> Reporter: Alex Sherwin
> Priority: Major
> Original Estimate: 24h
> Time Spent: 50m
> Remaining Estimate: 23h 10m
>
> Support OpenSSH client certificates for publickey authentication
> This extends the existing publickey authentication protocol described in RFC
> 4252 Section 7: https://datatracker.ietf.org/doc/html/rfc4252#section-7
> The extensions are described in
> [https://cvsweb.openbsd.org/src/usr.bin/ssh/PROTOCOL.certkeys?annotate=HEAD]
> Currently the MINA code base supports host key certificates (where the client
> can optionally validate a host certificate), but client certificates are not
> supported (where the client can use a certificate for authentication to the
> server)
