[Samba] Windows changes file ownership & ACL's - any solution ?

I thought I had read a response to this.  Went something like this:

Word (and lots of others such apps) do not actually deal with the original
file.  They create a temporary file which overwrites the original when you
save the new document.  The 'new' file of course inherits the new
editor's
ownership.

Hope this helps you.

Noel

I'm re-posting this only because I didn't get any responses before.  ANY
help 
is very much appreciated. 

I'm running SuSE 7.0, Samba 2.2.2 w/Winbind, Pam, on 2.2.20 Kernel w/ACL 
Support.

I have just verified that I'm having this same problem.  Exactly.  I saved a

file on a Samba share, then I verified I was the owner.  I then went to a 
co-worker's computer and opened, edited, saved the file with M$ Word.  Now 
when I look at ownership, it is set to him as the owner and the permissions 
are reset.  When I follow the same steps using Notepad, the ownership and 
permissions aren't changed.

Here are the settings for my share:

[share]
        comment = Test Winbind Share
        path = /mnt/share
        create mask = 0777
        browseable = Yes
        writeable = yes

Here is the ACL for the file before I edited it with M$ Word.

linux10:/mnt/share # getfacl acltest.doc
# file: acltest.doc
# owner: DOMAIN+$ejwk
# group: DOMAIN+Domain Users
user::rwx
user:DOMAIN+I10201:rwx
group::rw-
mask::rwx
other::rw-

Here is the ACL for the file After I edited it with M$ Word.

linux10:/mnt/share # getfacl acltest.doc
# file: acltest.doc
# owner: DOMAIN+I10201
# group: DOMAIN+Domain Users
user::rwx
group::rw-
other::rw-

How do we work around this problem.  

Anyone have any ideas or having the same problems ??

TIA

Josh Konkol

[Samba] Windows changes file ownership & ACL's - any solution ?

So then what good are ACL's if they're going to be overwritten each time
the
file is accessed?

Am I the only one here to sees this as a real problem?

I'm ready to implement Samba full-force, but this IMHO is a big issue.

ANY feedback right now is appreciated

[Samba] Windows changes file ownership & ACL's - any solution ?

Does an NT server behave any differently?

My solution is to not rely on the owner being any particular user.  Set
things up (either with default ACLs on the folders, or with 'force
group'
and 'create mode') so that the proper people will always have group
read/write access to the files.  This also lets you make sure that new files
will have the proper permissions.

For example, we might have an Engineering/R&D folder with default ACLs like
this:

DOMAIN+Engineering:rx
DOMAIN+R&D:rwx

Now every file and folder created in that directory will have read access
for people in the Engineering group, and read/write access for people in the
R&D group.  The only time it matters who owns the file is if someone wants
to change the attributes or ACLs on it, since attributes and ACLs can only
be changed by the owner or by root.

[Samba] Windows changes file ownership & ACL's - any solution ?

That is exactly what we do.  If you have an issue with only a single user
having rights to a set of files then ask them to create a new folder in
their shared area and they can change the ACLs to block access from others.
