(RADIATOR) 802.1x Authentication Unsuccessful - Could not find a handler for...

I actually tried it with *just* the <Handler> clause, and it worked...
so apparently the "TunneledByTTLS=1" portion isn't required...
Should I be using both handler portions? If so, why? It seems really
redundant to do things that way, and it is somewhat confusing.
I'm just trying to understand what's going on here... :-)
Thanks for the help!
