[Samba] Problem with permissions

[Bikrish Amatya]

Hi everyone.

I have to task where i have to replace windows NT server by samba. The 
problem i facing is with permissions. In windows NT , administrator can 
provide a share permissision like , full control, read & write but no 
delete and read. But  i have provide same functionality in samba server. 
How can i set such permission , write but no delete in linux through 
samba. I have googled a lot but couldn't  find the solution.

Any help would be apperciated.

Thanks
