I think I've found the problem. It seems we're asking for an ssh-connection method "password" and this server doesn't seem to allow password. Note that regular [OpenSSH] ssh asks for keyboard-interactive.

debug2: Unrecognized authentication method name: password
The application code isn't designed to be "driven" by a user, so keyboard-interactive didn't seem the right function to use. The question is, is this just a sshd configuration problem? Or should I be using libssh2_userauth_keyboard_interactive_ex() and then writing a callback function that simply returns the password as supplied by the app?
Many thanks!
