Unfortunately, I already use the latest module version (1.50) of the CIFS
module. Unless something related has changed in the kernel base, this should
give the same results...

This was a good idea. Using this flag, I can see my clear-text password appear
during the 'Session Setup AndX Request' step. Unfortunately, the account used
for the connection is incorrect (a concatenation of the Domain, the client OS
and the Lan manager without the very first letter) and there is no valid session
key (0x00000000).

You can access the capture file of this test here :

I'm going to file a bug report for that.
