How precisely is the file share mounted?
The error indication is that chmod() failed.
Does chmod() work on that filesystem?
Can you change the mount options such that chmod() will return success,
even if it does not actually change the permissions of the file?
that "noperm" in the mount options had the desired effect for one user;
note that that does not seem (to me) to match what the "mount.cifs"
documentation says, so you'll want to do your own investigation and
testing before relying on it.
