When building Security rules in a Device Group that need to allow traffic to specific users and groups defined in Active Directory, it's essential to have user and group information available in Panorama to select these entities for the rules.

D. A master device with Group Mapping configured must be set in the device group where the Security rules are configured:

The concept of a "master device" in Panorama refers to a specific firewall that is designated to provide certain settings or information, such as user and group mappings from Active Directory, to Panorama. This information can then be used across other firewalls within the same device group.

By configuring Group Mapping on a master device, Panorama can leverage this information to populate user and group objects. These objects can then be used in Security rules within the device group, allowing for the creation of policies that are based on user identity and group membership, as defined in Active Directory.

This setup ensures that Panorama has the necessary context to apply user- and group-based policies accurately across the managed firewalls, facilitating centralized management and consistency in policy enforcement.
