For correct operation of the scheduled job its advised that the job and
the webserver are operating under the same OS user account. If this is not
possible, you should either not use the DISK storage method
(file_upload_method) for MantisBT or you should adjust the global variable
attachments_file_permissions with the proper rights. In general its possible
to specify within the scheduled/cron job line which user should run the job.
