Hi Paul, Just double checked and found this is actually only a 'must' requirement for servers, unfortunately the requirements for clients are that they 'should' ignore unknown VSAs and attributes of an unknown type. I'm not entirely sure why that is, seems pretty dumb to me to reject a user if the packet contains VSAs from another vendor.
Honestly this is probably a bug in Juniper's RADIUS client implementation. We found a similar one in HP ProCurve's where the attribute offset wouldn't be incremented properly if a VSA was found with a non HP vendor ID... oops. Apologies for the slightly incorrect info.
