Thanks Alan...

I finally found the time to work on this issue, and so finally figured it out.  

I was using ipaddr = domain_name in the home_server definitions.  I remembered a problem I had with the freeradius client library wherein if I used a domain name, like localhost, instead of a "real" IP address to describe the server I needed to connect with, I'd get a failure.

Using the same proxy.conf file I sent in my first note and changing the ipaddr variable to instead of localhost for each home server allowed me to successfully connect to the primary radius server.  I won't have a secondary server set up until next week, at which time I'll test if the fail over to the secondary server work.  As I fully expect it to.

I assume it is a bug to be required to use and IP address instead of a domain name, so can you please point me to where I can file a bug report on this?
