-----------------------------------------
Hi Jason,
There are a couple of different modes you can operate your Windows server in.
When you say you've tested Windows 7 and Windows 8, I am not sure what you mean
by that. Specifically, what I think you would need to do is to read articles
like this one:
http://www.nbtnet.newboundary.com/support/docs/ppm/ppm/troubleshooting/tasks/ppm0114.htm
... and alter the configuration accordingly, to see how NTLM behaves. So this
is what I recommend:
(1) First, in the absence of any of your custom changes, try modifying a
server's configuration to cover all different variants, e.g. NTLMv1, NTLMv2,
and NTLM 2 Session Response. Use wireshark to be sure the NTLM exchange is
working as expected, and that all three modes are being exercised. Record the
Type 1 and Type 2 message flags from each configuration for later analysis.
(2) Now, make your custom changes, and repeat the process. Some of the Type 2
flags will change, and some of the protocol exchanges will fail to work.
Record the new flags and whether the authentication succeeded or not.
(3) Attach a matrix to this ticket with the following columns:
"Current/modified", "Type 1 flags", "Type 2 flags", "Success/failure" . From
that maybe we can figure out how to change the logic.
Thanks!
