    It works for me (OpenSSH 3.0.2p1). I use public key authentication.
    In my ".ssh/config" file, I set "HostbaseAuthentication=no" and
    "RhostsRSAAuthentication=nl". Those settings stop the server from
    attempting to validate the hostname of my connecting system. It
    still works without those settings, but I then get messages logged
    about mismatch between the DNS hostname and the hostname given by the
    SSH client.
