Problems with Redundant Proxy config with FreeRadius 1.0.1-2.FC3.1 (Fedora Core 3)

[Shaun Mccullagh]

Hi,

I would like FreeRadius to proxy requests to two radius servers.
Normally requests should go to a primary(kiezel1i), but if this is
unavailable it should send requests to a secondary(kiezel2i). I'm using
the config at the bottom of this message. If I shut the primary down,
FreeRadius never forwards the requests to the secondary.

Have I made a mistake in my config?

How does FreeRadius determine if the Primary is unavailable?

TIA

Shaun
