This read-write DisplayString (1-32 chars) defines the name of a RADIUS server group, a set of authorization attributes applied together to users. Naming groups lets an admin manage authorization policy, VLAN, ACLs, privilege level, for many users at once by assigning them to a named group rather than configuring each user individually. For example, an admin might create a group named guest-users and later assign several accounts to that group name so they all inherit the same restricted access settings.
