Server Configuration

Keyboard-interactive is not enabled by default on the server. To set up keyboard-interactive authentication, do the following steps:

  1. Include the following line in the /etc/ssh2/sshd2_config file: 
    AllowedAuthentications   keyboard-interactive
    Also other authentication methods can be listed.
  2. The submethods and policy for keyboard-interactive are configured as follows: 
    AuthKbdInt.Required       password
AuthKdbInt.Optional       password,plugin
AuthKbdInt.NumOptional    1
AuthKbdInt.FailureTimeout 2
...

    The default number of optional submethods that must be passed is 0, although if no required submethods are specified, the client must always pass at least one optional submethod.

    See the sshd2_config man pages for more information on the keywords (Appendix sshd2_config).

  3. (Optional) You can configure password change for the password submethod with the two configuration variables described in Section User Authentication with Passwords.
  4. Restart the server as instructed in Section Restarting sshd2.
