Understand the following Microsoft Vendor Specific RADIUS attributes:

Browse Source 
RAD_MICROSOFT_MS_MPPE_ENCRYPTION_POLICY
  RAD_MICROSOFT_MS_MPPE_ENCRYPTION_TYPES
  RAD_MICROSOFT_MS_MPPE_RECV_KEY
  RAD_MICROSOFT_MS_MPPE_SEND_KEY

These attributes may be supplied by a RADIUS server when MSCHAPv2 is
used to authenticate.

It *should* now be possible to build ppp with -DNODES and still support
CHAP/MSCHAP/MSCHAPv2/MPPE via a RADIUS server, but the code isn't yet
smart enough to do that (building with -DNODES just looses these
facilities).
