Backend Retry option

[Craig T. Hancock]

When configuring your backend authentication and authorization system how
does the retry option work. What I want to know is when connecting
to the backend server and if it fails to connect given a specified time
does freeradius cache the IP address after the first DNS lookup of the.
server DNS name specified in the radiusd.conf file. Or does it attempt to do
a DNS lookup on the server IP address on each retry.

I am trying to investigate the possibility of load balancing my 
authentication
backend through Round Robin DNS.
