Configuring secure shell (ssh) for multi-factor authentication
If you are planning to require multi-factor authentication for secure shell (ssh) sessions and you want to use a native secure shell package, you should review the settings in the secure shell configuration file (sshd_config) to be sure that the ChallengeResponseAuthentication option is set to yes.
You can edit the file manually or enable the “Allow challenge-response authentication” group policy to automatically configure this setting. You can find this group policy in the Group Policy Management Editor under Computer Configuration > Policies > Centrify Settings > SSH Settings. For more information about adding, enabling, and applying Centrify group policies and the other group policies you can use for secure shell sessions, see the Group Policy Guide.
