I did not say that you cannot use cifs, I said that it isn't part of
Samba and if it is causing your problem, then Samba cannot fix it, I
would start by reading 'man mount.cifs'

Are we talking about a program creating a temp file, then modifying the
temp file, then when you save it, it deletes the original file and then
renames the temp file to the original file ? If so, the new file should
get the same permissions as the original file, if it doesn't, then you
need to talk to whomever wrote the program.

If I locally modify a file in a share directory, close and save the
file, the permissions do not change.
