[RADIATOR] Redudant servers with AuthBy DNSROAM

[Heikki Vatiainen]

Hello,

experiments with RadSec and AuthBy DNSROAM seem to indicate that
Radiator does not do fallback to next server even if multiple servers
are listed for a realm in DNS.

In other words, if there are servers A and B listed in DNS that could
handle RadSec for a domain, Radiator always tries e.g., A and never
switches to B even if A does not answer. It would be useful to have a
timeout so that next server from DNS could be tried.

I guess this topic was discussed earlier too:

How should the dead host scenario with RadSec and DNSROAM be handled? If
there are two servers what are the options to try the other server if
the first one does not answer?
