FreeRADIUS Proxy Problem

[tnt at kalik.net]

>I've got a really frustrating problem with FreeRADIUS trying to proxy to a Microsoft IAS.  I'm using FR 1.0.1 (I know, it's old).  The problem is that I have proxying configured, but I keep getting Access-Reject back from the IAS.  The IAS says that I used an unknown username or password, but I know that the username and password is correct.  I know this because I have a test FR box with the same config and same version (1.0.1) that works fine.

>I assume that the User-Password is not being passed on properly, but I can't imagine why.  I looked into the PAP authentication config and both the working test box and the non-working production box are configured to use 'crypt'.  Can anyone point me in the right direction?

You can actually make sense of IAS logs:
