Authentication method

[Fabio Leone <fab.leo@xxxxxxxxx>]

Hi.
I'm using libssh version 0.6.3.
When logging in on some servers ssh_userauth_list() returns zero (I call
ssh_userauth_none before).
What is the right way to access the server in that case?

This is a snippet of my code:

  ssh_userauth_none (node.session, NULL);
  node.auth_methods = ssh_userauth_list (node.session, NULL);

  if (node.auth_methods & SSH_AUTH_METHOD_PASSWORD)
    {
      ...
    }
  else if (node.auth_methods & SSH_AUTH_METHOD_INTERACTIVE)
    {
      ...
    }
  else if ...
     ...
  else
    {
      sprintf (p_auth->error_s, "Unknown authentication method for server
%s\n", p_auth->host);
      ...
    }
