This is very likely the problem.  It's yet another Microsoft-STAC hook,
Microsoft Point-to-Point Compression (MPPC) CCP using Microsoft Point-to-
Point Encryption (MPPE).  Successful MPPC negotiation can be mandatory when
when MPPE is requested.  The draft says "should" but you can bet that
becomes "must" in the eyes of the NT PPP implementator. :(

Since MPPC must be licensed by STAC Electronics there is no code for it in
pppd.  AFAIK the only way it could be used in Linux is by a binary module
that was generated under the STAC license. 

The gory details can be found at
