Solution trouvée sur un site en anglais:
After a lot of reserching and testing, I found a solution to the problem. Its a very easy workaround:
------------------ SOLUTION ------------------------
in /etc/samba/smb.conf add the following to the bottom of the [global]
section:
client lanman auth = yes
client ntlmv2 auth = no
-------------------------------------------------------
Look for this 2 post for the explanation of the solution:

As you can see in my question, I had the first line already and that worked for all version prior to 12.04LTS, but in this new version you MUST add the second line too which was option before.
Hope this helps!!!
Et ça marche!!
