[Samba] very odd behavior for concurrent file access in Samba3.0.0 with MS Word

[Vladuta Cristian]

Hello, 

I just installed Samba 3.0.0 on RH9 and began testing the concurrent file access behavior. 

Leaving all locks/oplocks by default, there is no way of preventing a second MSWord user from opening  an already open file with no warning message (in a MS network the message would normally be " ..test.doc is already open by ...Do you want to make a copy?")!! No such thing with Samba, as the second user might waist hours on editing an already open file just ending with no results!! Don't you think this is stupid?

How can you advert other users that a file is already open in such situations?  I just want to avoid confusion and make the transition from a Windows file server to Samba transparent.
Thank you,

Cristian
