Hi Nikos, I noticed ocserv 0.11.6 includes an Acct-Session-Id with the Start packet, but not with the Interim-Update packets. Is this the correct behaviour? If so, is it possible to (optionally) add the Acct-Session-Id to all accounting packets? (If I understand RFC2866 correctly the Acct-Session-Id is required for all accounting requests.)
