Forbid two users to read and write the same file

[Franck Y <franck110@xxxxxxxxx>]

Hello everyone.

 

I have a problem dealing with samba!

 

I have several folder that i share in my harddrive, one of those is PROJET

The problem is i don t want two user to open the same file. In fact i would like a user

to pen the file and the other one to open it in realdonly.

 

Can you tell me whats wrong with my configuration.

 

regards,

 

Franck
