not easily or at all if you use proxying - as all you'll get back is a reject/fail and
that'll be it.

ideally what you want to do is configure the FreeRADIUS server to talk to both of the
authentication servers....and if the first one fails then dont care and continue onto
the second one...etc etc. you need to check the fail-over section of the WIKI

particularly the 'More Complex Configurations' section.

we actually use this to talk to 2 AD systems and 2 Kerberos systems - because
people are in one or the other...each system has different credentials and
different DOMAIN etc...but the mschap and krb5 sections of FreeRADIUS are very flexible
(we took the modules and have a mschap-new and mschap-old etc with correct parts in).

works great! PEAP, TTLS etc - we dont care. we just deal with it.
