There isn't very much. The RADIUS server need to be configured to accept
normal "obfuscated" plain-text authentication as defined in the RADIUS
protocol specifications (Access-Request with the User-Password
attribute), and both need to be configured with the same shared secret.

squid_radius_auth does not support syntesized CHAP-MD5 authentication.
Contributions adding such support is welcome which may make it easier to
interoperate with some RADIUS servers but probably not MS AD.. (what I
mean is squid_radius_auth calculating a CHAP response based on the
received plain-text credentials)
