  Which I wrote.  I *do* understand how the server works.

  The *default* install does not require you to add "authorize" or
"authenticate" sections to radiusd.conf.  The *default* install includes
a "default" virtual server, with those sections already defined.  The
*intent* as per the "man" page and other documentation, is for that
default server to be used as the basis for your own policies.

  The only time you *have* to add "authorize" and "authenticate"
sections to radiusd.conf is when you've edited the default install to
remove all references to virtual servers.

  Feel free to send a first draft of suggested documentation.

  Yes.  The internal data structures change.  See libradius.h for
complete definitions.
