Hi all,

on my organization I have, on CentOS 6.5 x86_64, Samba 4.1.4 compiled and 
installed from source tarball.
Samba acts as AD and fileserver.
The problem is when the users try to save AutoCAD files on a share where all 
domain users have R+W rights.
Autocad refuses to save a file formerly saved by another domain user.
The message is: "AutoCAD unable to save drawing as it is being accessed by 
another session". Obviously, this is false: there is no other session 
accessing the file.
By the way, other kind of file, like Word, Excel, PDF, etc. don't show this 

My smb.conf::

# Global parameters

        workgroup = MYORG
        realm = MYORG.LOCAL
        netbios name = FILESERVER
        server role = active directory domain controller
        dns forwarder =

        path = /usr/local/samba/var/locks/sysvol/myorg.local/scripts
        read only = No

        path = /usr/local/samba/var/locks/sysvol
        read only = No

# common share

        # this is the share where I have problems with AutoCAD files
        path = /home/condivisione
        read only = no
        create mask = 0777
        directory mask = 0777
        force create mode = 0777
        force directory mode = 0777

# user share

        path = /home/j.smith
        read only = no

        path = /home/t.hill
        read only = no

        path = /home/l.dicaprio
        read only = no

Any ideas?
Thanks in advance and sorry for my english :-)
