  RADIUS is *very* dependent on IP addresses.

  PLEASE follow instructions.  We don't need the extra crap produced by
"-Xxx".  Just "-X" is good enough.

  The point of the debug output is that you usually don't need to post

  So... what's that entry on line 22?  Does it contain a password for
the user?

  Which means that entry doesn't contain a password for the user.
