  Uh... why?  FreeRADIUS does come with dictionaries.  Why go to a 7 year-old third-party GitHub account, when you could get the, directly from FreeRADIUS?

  There's no error, because the log message doesn't say "error".  It's just a warning message,  You can ignore it.

  The server has no idea whether or not the NAS disconnected the user.  The only thing that FreeRADIUS sees is a Disconnect-ACK.
