  Yes.  But you will need to change the key used to assign IP addresses.

  Yes.  Because the default is to assign the IP based on MAC address.

  Yes.  But only *you* know what that unique parameter is.  You can
discover the unique parameter by reading the debug output.  Compare
packets for two sessions, and see what's unique.  Then, change the SQL
queries to use that instead of using the MAC address.

  Accounting is not important.  What's important is what's in the
Access-Request packet.
