VRF config from v2 to v3

Hi there, A long time ago someone set up a freeradius server within our company and used the following patch places in policy.txt for vrf users - http://lists.freeradius.org/pipermail/freeradius-devel/2005-November/000699.... After searching around I am not sure google has any answers for me for a v3 version. I wondered if anyone has the unlang config for this? Thanks, Rich
