Unfortunately it doesn't seem that MS-CHAP is supported without a custom 
build of PPPD. That leads to a real rats nest of problems with the latest 
sources:

can't locate "des.h" if USE_CRYPT is undefined

USE_CRYPT uses the non-exportable crypt routines

chap_ms.c has missing includes for string.h, unistd.h

chap_ms.c has a number of missing prototypes for internal routines

chap_ms.c uses MD4 routines including a "reverse" function that's nowhere 
to be found while the rest of PPPD uses MD5 routines. (Can these be 
mixed? Should they be?)

Has anyone successfully build PPP 2.3.1 with the MS_CHAP option?
