radius_add_server ( resource radius_handle, string hostname, int port, string secret, int timeout, int max_tries )
radius_add_server() may be called multiple times, and it
may be used together with radius_config(). At most 10
servers may be specified. When multiple servers are given, they are tried
in round-robin fashion until a valid response is received, or until each
server's max_tries limit has been reached.
