Nope. Acct-Multi-Session-Id handles IDs for multiple sessions. What does that mean? No one knows... the IETF RADIUS working group has had discussion on that topic, with no resolution.
For 802.1X purposes, it is, I thought, pretty well defined in RFC 3580... No?
No. Every re-auth is a new connection. Always. Anything else is madness.
You have to correlate over these if you want to be able to limit the number of concurrent devices a user is allowed to have connected though, surely? Certainly NASes that implement the Acct-Multi-Session-Id support persist that value across re-authenication whether there is an authorisation exchange or not. Nick
