Yes, you need to remove the oplocks that Samba is
granting to clients in order for the Windows locks to
be seen by the UNIX clients.

Try adding the following two lines to your smb.conf,

oplocks = no
strict locking = yes

This will slow Samba down some but will cause the Windows
locks to be correctly seen under UNIX.
