Yes, to enable the unicast forwarding on the system you have to be a
root. In fact, you have to be root for other operations including
sending the OSPF raw packets.
To track-down the above error, the first thing to check is whether
the above file (/proc/sys/net/ipv4/ip_forward) really exists and
whether it is writeable (by root).

In any case, I believe the problem you are having with OSPF is not
related to the IP forwarding flag, but it is better to fix the above
problem first.
