To enable keyboard-interactive authentication, make sure that you have the following line in the /etc/ssh2/ssh2_config file:
Keyboard-interactive is enabled by default on the client.
Note: The client cannot request any specific keyboard-interactive submethod if the server allows several optional submethods. The order in which the submethods are offered depends on the server configuration. However, if the server allows, for example, the two optional submethods SecurID and password, the user can skip SecurID by pressing enter when SecurID is offered by the server. The user will then be prompted for a password.
