As I at first assumed...So, this is a bug after all.  If I put ipaddr = localhost in a home_server definition I get the failed authentication I described in my first note.  You can see in proxy.conf configuration lines I included, where ipaddr is set to localhost for all four home_server definitions.

As soon as I changed the ipaddr parameter in all four home_server definitions, and reset the server, I was able to properly authenticate.  Nothing else was changed.

I'll write a bug report on the site.

BTW,  I found a similar issue in the radius client library.  Using a host name in the configuration file causes a crash.  I need to report that as well.  I've run it in a debugger and can tell you where it fails.
