samba - Sep 2014 - Issue with Samba 3.6.3 and DFS Windows 2008 R2 share

Hi there, it's quite a week that I'm trying hard on this . To make it
simple:
- ubuntu 12.04
- samba 3.6.3

I'm trying to mount with CIFS the following corporate share:

mount -t cifs //cop.gen.net/fsgruppo/DISCO_GEN/Flussi/AG1  /mnt/ -o
username=johndoe

Mounting this returns a

"mount error(115): Operation now in progress"

I can mount directly the share which is " //cop.gen.net/fsgruppo" but
then
I can't do anything, for example I can't even do  a simple "ls
DISCO_GEN"
 as that will only return some message like "the folder is remote" .

Does anyone have some clue?
