[Samba] write locks

[Dawid Tomczykowski]

Hi!
I'm wondering if something is changed in write locks. I remember that when 
a windows user connects to a samba resource (file) to write something he 
set a write lock on that file. Then a second user, linux user (by samba), 
connects to the same resource to write something he breaks first user 
write lock and he locks file for himselfs. Can you tell me is taht problem 
is resolved or something? Or can you tell me an advice how to prevent 
linux samba client from doing that?

Greets,
