19 username - Username which will be used while authenticating. Note that
20 most server implementations do not permit attempting authentication
21 with different usernames between requests. Therefore this must be the

24 username_len - Length of username parameter.

26 Send a SSH_USERAUTH_NONE request to the remote host. Unless the remote
27 host is configured to accept none as a viable authentication scheme
28 (unlikely), it will return SSH_USERAUTH_FAILURE along with a listing of
29 what authentication schemes it does support. In the unlikely event that
30 none authentication succeeds, this method with return NULL. This case
