Keyboard-interactive is a generic authentication method that can be used to
implement different types of authentication mechanisms. Any currently
supported authentication method that requires only the user's input can be
performed with keyboard-interactive.
Currently on SSH Tectia Server for IBM z/OS, the supported submethods for keyboard-interactive are
password and plugin.
Methods that require passing some binary information, such as public-key
authentication, cannot be used as submethods of keyboard-interactive.
But public-key authentication, for example, can be used as an additional method
alongside keyboard-interactive authentication.
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.
Keyboard-interactive is not enabled by default on the server.
To set up keyboard-interactive authentication, do the following steps:
Include the following line in the /opt/tectia/etc/sshd2_config file:
Also other authentication methods can be listed.
The submethods and policy for keyboard-interactive are configured as
