there's User-Password attribute, with which you can do anything you
want (i.e. insert to db using unlang)
there's auth_badpass and auth_goodpass in radiusd.conf if you just
want to log it in radius.log.

Again, it's only possible if the user uses pap. It should be possible
to configure FR to only use pap (i.e. disable chap and friends). Most
clients can use pap as fallback, so they should be able to still
