Well with EAP-TTLS/PAP, the RADIUS server gets the plaintext
password from the client, so can do whatever backend auth
mechanism it likes...

I'm not thinking about security concerns handling plain passwords;
we can be as protective about the RADIUS server as the Windows
guys can be about their DCs, and the NTLM hash is nearly as good
as plaintext anyway, hence the reason they may want to kill it

Agreed. EAP-TLS would be a lot nicer, but requires a lot more
effort for on-boarding. We have enough complaints about the client
setup processes as it is (and they really aren't that hard).

It's the usual story with something "extensible". You end up
having to run the lowest common denominator, which is probably
tantamount to crap. SSL and crypto algorithms, anyone?
