smbclient 3.5 can't connect to a Windows 7 server using NTLMv2 where smbclient 3.3, 3.4 and 3.6 can

[Blohm, Guntram (I/FP-37, extern)]

Hi all,

problem is: company security says I have to use NTLMv2, so I sent "client NTLMv2 auth = yes" in smb.conf. No problem with RedHat 5.6 clients (which use smbclient 3.0.33); RedHat 6 clients (smbclient 3.5.4) stopped working with NT_STATUS_LOGON_FAILURE.

To make a long story short, I downloaded versions 3.4, 3.5 and 3.6 from enterprisesamba.org and tried each of them. Here's what happened:

[root at is0lavm59 bin]# pwd
/tmp/enterprisesamba.org/3.6/usr/bin
[root at is0lavm59 bin]# ./smbclient -V
Version 3.6.7
[root at is0lavm59 bin]# ./smbclient -d 10 -L audiinc11280932 -U audiinc11280932/smbtest%blaBla1234. 2> /tmp/smbclient-3.6.log

Seems like a bug in 3.5 to me, which happens (at least) with  the 3.5.4-68.el6 that comes with RedHat 6, the 3.5.11-79.fc14 from Fedora 14, and the 3.5.16 from EnterpriseSamba.org. Any ideas, or any extra configuration that might geht 3.5 working?

I put the -d 10 log files, as well as tcpdump trace files, into the attached zip file.
