IIRC, this is just so that the user 'anonymous' is never treated as a real
user so no real challenges regarding this ID are sent to the LDAP or SQL backend?
We've never had to define an 'anonymous' username anywhere in FreeRADIUS
config for this to not be a problem....basically, if you have anonymous at realm
then FreeRADIUS suffic/realm/prefix code will note the realm part and proxy
it through..and its its EAP it'll be proxied to the inner-tunnel (from then
on the InnerID is what matters!)

thats the default EAP type and hence the one that is initially challenged... if
you want to optimize things then set it to you most commonly used method....we have
it as 'peap' here but you'll be EAP-TTLS/PAP'ing? so that'd be 'ttls'
