  So... where do we have to put the documentation where people will read it?

  The default config says:

	#  Access-Reject packets are sent through the REJECT sub-section of the
	#  post-auth section.

  Which seems clear

  If you read the debug output, you'll see that Access-Accepts are run through the "post-auth" section.  And Access-Rejects are sent through the above section.

  That's it.  5 minutes of testing, and you'll see exactly what it does.

  The general frustration here is that there's a *ton* of documentation, comments, and examples.  Instead of making things clearer for people, it seems to make things worse somehow.

  If ONLY there was some kind of debug output you could read, to see what the server was doing.

  This isn't difficult.  If the document says "if does X", then it does X.  It doesn't mean that it randomly does Y, or Z, or maybe Q.

  Maybe the Access-Reject packets are *also* sent through the "accounting" section.  After all, the documentation doesn't say that _doesn't_ happen.  Should we fix that, too?

 There's an infinite number of things which *might* be possible.  It is unreasonable to document them all.  Instead, we document what the server does, and then leave the reader to make the logical conclusion
