If I'm reading raddb/proxy.conf correctly home_server_pool allows for fail-over and load-balancing configurations. In my case I was to try the same credentials against multiple servers. I'm currently using this bit of unlang to send some requests to another radius server:

	if (User-Name !~ /^..[0-9][0-9][0-9].*$/) {
		update control {
			Proxy-To-Realm := ''

What I'm looking at doing is to retry failed proxy attempts locally. Is this possible?
