samba - Oct 2003 - [ACL] granting modify but not delete permission to a file

Hi.
In WinXP I can setup the permission of a file so that a user can modify 
the file,
but he can not delete the file.
I wonder if this is posible in Linux + ACL patch + Samba 3.0 compilled 
with --with-acl?

Many thanks
Oliver

Hi , the failure must be on your site, i tested this things on my setup and
it works,
check the permissions on the linux server, and your smb.conf .
Regards

In posix ACL is no equivalent to Windows's "enable/disable delete"
attribute. Generally, if user have write access to a directory he can 
delete/rename file even he is not an owner of file. The only way to 
prevent him from this is to set a sticky bit on a directory containing 
your files. It tells to Linux - "only the owner of file can 
delete/rename it". Access rights of others then depend on rwx/ ACL
settings.
