To simplify group-based policy configuration
and enforcement, you can now
share group mappings across
virtual systems. When you configure a virtual system as a hub, other
virtual systems can refer to the hub for mappings when they need
to identify groups instead of each virtual system collecting the
information independently.
If the same group mapping on
the local firewall differs from the group mapping on the virtual
system hub, the firewall uses the local mapping.
Use the same format for the Primary Username
across virtual systems and firewalls.
