  Does the database contain information for the first user session?  If not, that's the problem.

  Also check the attributes in the packets.  Does it look like the user is logging in via the SAME session?  i.e. Look at the two sessions.  Are the attributes identical (other than EAP-Message).  If so, then it looks like the user is logging into the same session, twice.  Which is allowed.

  That's good.

  There's no debug message saying "This is why Simultaneous-Use is going wrong".  There ARE lots of debug messages showing what it's doing, and why.  You've got to read them, understand them, understand what the server is doing, and go on from there.
