There are several vunlerabilities in the Radius protocol (replay attacks,
etc.). This is why Diameter was proposed as the replacement standard. No one
has seemed to really get behind it for some strange reason though.
You should read this:

if you haven't already. Also, other than vulnerabilities in the protocol,
looking at the backend (i.e. LDAP, SecurID, etc.) can be extremely fruitful.
