Hi.
Some configurations enable "password" password authentication, others
enable "keyboard-interactive" password authentication. Yes, it is
confusing. And yes, it is what forced me to implement keyboard-interactive
authentication in libssh2 in first place.
If you run ssh -v, you'll see "Authentications that can continue" lines in
the output. First one contains a full list of authentication methods
accepted by the server. I'm pretty sure the hosts which you can't connect
to using libssh2 will not have "password" init, but "keyboard-interactive"
only.
Best regards,
Mikhail Gusarov.
