If you want to configure multi-factor authentication for UNIX and Linux computers in classic zones or in Auto Zone, you must follow different steps than in hierarchical zones. For multi-factor authentication on computers in the “legacy” types of zones, you must either enable and apply group policies or set configuration parameters.
You can find these group policies in the Group Policy Management Editor under Computer Configuration > Policies > Centrify Settings > DirectControl Settings > MFA Settings. For more information about adding, enabling, and applying Centrify group policies, see the Group Policy Guide. For more information about setting configuration parameters, see the Configuration and Tuning Reference Guide.
