OSPFv3 authentication

Hi

Does Fortigate FortiOS 5.2/5.4 or 5.6 support OSPFv3 authentication? I couldn't find authentication command under OSPF interface configuration

#config router ospf6

config ospf6-interface edit "port1" set area-id 0.0.0.0 set interface '' set retransmit-interval 5 set transmit-delay 1 set cost 0 set priority 1 set dead-interval 0 set hello-interval 0 set status enable set network-type broadcast next end

Thanks
