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. -- ****************************************************** Craig T.
