    It's not an incompatibility, it's just that your client either does not
    support keyboard-interactive or has its support disabled and the server
    does not have SSH password authentication enabled.

    On an OpenSSH client, this is controlled by the
    "PreferredAuthentications" setting. Check the documentation for your
    client for an equivalent and enable it if it has it. This is the
    preferred solution.

    Alternatively, you could also set "PasswordAuthentication yes" in the
    server's sshd_config. On a vanilla OpenSSH 3.8.1p1 this will prevent
    PAM from being used for the authentication, I'm not sure if this is the
    case for the FreeBSD version.

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