[Samba] mount.smbfs and NTLMv2

[Pascal A. Dupuis]

Hello,

context: Samba-3.0.2 on a i386 debian-sarge linux, 2.4 kernel.

All the windows machine on our network switched today to NTLMv2, and
mount.smbfs can't access anymore ressources which are available to
smbclient.
Exerpt from smb.conf:
        client NTLMv2 auth = Yes
        client lanman auth = No
        client plaintext auth = No
 
The rest being default.

Doing 

smbclient  -L server  -U user -W wg -d 3 2>&1 | more

results in

While

mount.smbfs service mountpoint -o workgroup=wg,username=user,debug=6

results in

So, does mount.smbfs support NTLMv2 ? Is there some special
option/compile flag to use ?

TIA
