I did the same some weeks ago with some boxes, much better now.

You have to tweak the Registry. Delete the SPAP and CHAP keys in
/HKEY_LOCAL_MACHINE/SYSTEM/CURRENTCONTROLSET/SERVICES/RASMAN/PPP/
(and yes, do it again every time you have changed somthing on your box)

The RADIUS server can't handle the SPAP/CHAP encryption (MS-specific).
