[Samba] "delete list" parameter

[Vinay Pawar]

Hi,
Samba has the "read list" and "write list" parameters in smb.conf.
I'm looking for a patch that provides a "delete list" option.
So that only that list of users can delete files or directories
in that share. I know the filesystem doesn't natively have a delete
bit, but couldn't it be done on the samba level, independant of the 
filesystem.

Thanks,
