Subject: NetLMv2 / NetNTLMv2 Bug Fix Patch


I've uploaded a small patch against John 1.7.5 + Jumbo 3 for my
NetLMv2/NetNTLMv2 formats:

The patch makes the following changes:

* Fixes a bug which surfaces when cracking NTLMv2 authentication
exchanges with very long client challenges. These seem to occur when
both ends of the exchange are Windows 7 hosts. 

* Fixes domain parsing for LMv2. I was previously upper-casing the
domain name and should not have been.

* Makes username format for NTLMv2/LMv2 more flexible. The file can now
contain either "DOMAIN\USER:::" or "USER::DOMAIN:".

Please let me know if there are any questions or issues.
