samba - Dec 2003 - can delete files but not overwrite

Hello-

I have users complaining since we deployed samba 3.0.0 that they can not
overwrite existing files.  I'm not sure if it was the change to 3.0
which is the problem as other chages also happened during this migration
(security=DOMAIN from security=SHARE,  XFS file system,  new kernel).

The clients can delete, rename, and move the file,  but they can not
update it.  All users are in a common primary unix group and the file
has its group bits set to this group.  

Any idea what I might want to look at to resolve this?


linux system running rh9, samba3, kernel 2.4.21-xfs.  Here is the
smb.conf contents.


thanks again folks!

greg
