It might be smbd that is reporting the error, but it is coming from
this block of code:

fd = open(p, O_RDONLY);
if (fd == -1) {
	DBG_ERR("/proc open of %s failed: %s\n", p, strerror(errno));
	return map_nt_error_from_unix(errno);
}

It looks to myself that Samba is trying to open a file, but the
permissions on that file do not allow it.
