That's a vendor-modified version of OpenSSH.  Assuming it corresponds to
what's in FreeBSD head, there's about a thousand lines of changes.
Browsing through the diffs I don't see anything that could obviously cause
it, but I am far from sure.

Can you reproduce the problem with an unmodified version from openssh.com?
Failing that, can you get the server-side debug output from a failing
connection (ie /path/to/sshd -ddd)?

Thanks.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
