I have a samba 3.5.6 joined to my samba AD. I set this share: [Nodo$] path = /media/almacen/Admin/Windows/ read only = yes valid users = @EPEPM + epepm_nodo >From Windows XP only users from this group epepm_nodo are allowed. But when I try from Windows 7 any user is granted access to this share. Any help will be really appreciated. Felix.
