LMv2 challenge/response authentication typically takes place when the GPO "Network Security: LAN Manager authentication level" is configured to a setting that enforces the use of NTLMv2, such as "Send NTLMv2 response only\refuse LM & NTLM." IIRC, Microsoft Vista now sends NTLMv2/LMv2 by default. I've uploaded a diff against John 1.7.2 with the Jumbo patch applied: http://www.foofus.net/jmk/tools/jtr/john-1.7.2-all-9-netlmv2-jmk-1.diff Hopefully this is useful to others. If anyone sees some areas in which it could be improved, please let me know.
