[Samba] Samba Scenario

Hi All

I have been asked by my company management to look into moving file share
server from Windows 2003 server OS to Ubuntu 10.4 using Samba. I have
successfully configured active directory authentication using winbind and
have configured samba  and am able to access my file share successfully.

The complication arise as a result of implementing ACL mappings on Linux, as
I need fine grained control over specific subfolders and files. From what I
have read, I cant map all 13 permissions to respective unix rwx permissions.
I have a use case where a certain group called A has read write execute
rights on a folder/file but they shouldnt be allowed to delete the specific
folder/file. On windows, all I have to do is set up my security permissions
to deny 'delete subfolders and files' and 'delete' and it works well. In
linux world I understand I cant do this as the user has rwx permissions on
the folder/file and he can do whatever he likes.

I googled a lot around this issue and found that if you set up sticky bit on
the directory I can still read and write from the file or directory and wont
be able to delete it. It works in case of most document types but MS office.
