I did some research on this and it definitely appears that the SSH
protocol supports clients suggesting/requesting which auth method to
use when connecting. j2ssh used to use to do this for us. Does JSch
allow us to something similar? I believe j2ssh used the message id 50
which it called SSH_MSG_USERAUTH_REQUEST.

Would it also be possible to get some documentation on UserInfo
interface and it's methods. I'm not clear about what they all do. John
Stote did provide me some implementation examples.
