  Go read my message again.  The problem is NOT the proxy.  The problem
is the home server.  If you noticed, the proxy debug mode shows that the
HOME SERVER is rejecting the requests.  The proxy is simply at the mercy

  That's nice.  Ask him why it's returning Access-Reject for your users.

  The home server is rejecting the user.  No amount of playing games
with the proxy will fix the home server.  You could install 1.1.7,
2.0.5, Cisco ACS, Juniper's SBR, Radiator, or nearly any other RADIUS
server on the proxy and IT STILL WOULD NOT WORK.

  Go fix the home server so that it doesn't reject your users.  Yell at
it's admin, if necessary.

  Stop playing games with the proxy.  You're wasting your time.
