This is probably a *different* error that the one the OP is seeing.

The OP is seeing an error where you save a document on a group share
that belongs to someone else. Office attempts to replicate the
permissions on the new file gets confused by the various DOS attributes
not working quite like they do on a real Windows file server resulting
in messed up permissions. Specifically the person saving the file owns
the file but has no permissions to actually access the file.

It only happens with Office 2007/2010 and only if you are using ACL's on
the share, and then only if the DOS attributes are being mapped onto
Unix permissions rather than being stored separately in the files
extended attributes.

This is all in Samba 3.5/3.6 as far as my testing goes. Operating in a
higher educational environment there is no reason to move to Samba 4.x
yet. Samba 3.6 is just fine for serving files and campus agreements make
running real Active Directory servers very cheap.
