This option allows you to enable or disable nested groups support. By default, the Enable nested groups support option is set to ON.
If Enable nested groups support option is set to ON, then Advanced Authentication will authenticate all the users of the group and its nested groups assigned to a chain. If Enable nested groups support option is set to OFF, then Advanced Authentication will authenticate only the members of the group assigned to the chain. The members of the nested groups cannot access the chain.
Consider there is a group by name All Users assigned to SMS Authentication chain and the All Usersgroup has subgroups Contractorsand Suppliers.When Enable nested groups support option is set to ON, then Advanced Authentication will authenticate All Users group and the nested groups Contractors and Suppliers for SMS Authentication chain. When the option is set to OFF, then Advanced Authentication will authenticate only the members of All Users group and the nested group members will not have access to SMS Authentication chain. This improves the login performance of the appliance.
