I have been googling and googling and can't find a conclusive answer. In log files for samba, I see things like the following:

"[11560]: pam auth crap domain:" &
"NTLM CRAP authentication for user"

I'm hoping this stands for something like "Challenge Response Auth Protocol" or something, but when I show the logs to people that aren't technical, I usually get questions or looks. Anything that anyone knows about this will greatly help.


  • If I remember correctly, it's something related to PAM when authenticating – Mark Henderson Mar 16 '10 at 21:59

C hallenge R esponse A uthentication P rotocol.

See: http://wiki.samba.org/index.php/Winbind#CRAP ("I think the pun is intended.")

  • Wow, and I was just guessing. I guess it makes sense, then. Thank you. – Tim Cronin Mar 16 '10 at 22:21
