Re: problems with ssh_userauth_list

[Tilo Eckert <tilo.eckert@xxxxxxx>]

You did not check the return code "rc".

You could already be logged in after the ssh_userauth_none() call (e.g.
IP based auth). An error could occur (SSH_AUTH_ERROR) or if you are in
non-blocking mode SSH_AUTH_AGAIN could be returned.
