[erlang-questions] User provided authentication function in ssh_cli

[Anders Nygren]

While working on an ssh based cli, using ssh_cli, I discovered an
undocumented feature.

start the listener with

ssh_cli:listen(UserFun,Port,[{pwdfun,F}])

where
F(User,Passwd) -> true | {false,Reason}

And F will be called to vaildate the user/password.
