Some RADIUS servers (some rare accounting proxies) exhibit
broken behaviour in that the reply does not come from the same address
that the request was sent to! This broken behaviour would normally cause
Radiator to ignore replies from such broken servers. The optional
ServerHasBrokenAddresses flag will permit interoperation with such broken
servers. Can be overridden for an individual host inside its Host
clause.
WARNING
Enabling this for _two_ remote servers at
the same host will cause difficult to trace problems.
