sending Group-Name in accounting Packets to FortiGate

[Somanath Mishra]

Hi,
  I am forwarding accounting packets to fortiGate , but Group-Name is
missing in this packet. Group-Name is coming in radacct table. So to
show Group-Name i modified radacct table, after that it showed. So same
need to do , i guess. Can you suggest where need to modify to get
Group-Name in forwarding packet?
