Yes, the message buffer contains binary data and will contain \0's
before the end of the string.  The length of the string is
SmbLength(&ntlm_request), not strlen (&ntlm_request).  You need to print
SmbLength(&ntlm_request) characters (preferrably as hex to avoid control
characters...) from the message buffer to see all data.

Btw, you can check out how GNU SASL uses libntlm, see
gsasl-*/lib/ntlm/ntlm.c.
