  You're getting caught up in terminology, and are ignoring my comments.

  Not entirely... EAP session resumption can be used during a re-authentication.

  In which case you know it's the same user as before.

  If EAP session resumption isn't used, you can still look at the *other* data, and tell that it's the same user, same MAC, and same AP.

  Since you control Class, you can send the same Class back for the re-authenticated session.  And therefore the "unique" accounting session ID will be the same.

   don't know what point you're trying to make.  Please explain your point, instead of quoting RFCs about re-authentication.  I can read the RFCs.  I can't read your mind.

  As I said, the RFCs are silent on this issue.  There is no way to tell if this behaviour is correct or incorrect.
