Introduction

It is possible to enforce different permissions for selected groups of users. This is useful for scenarios like

  • Increase the upload limits for Confluence admins to handle exception scenarios

  • Only the media team users can upload videos files which are large in nature

  • Restrict maximum size of images (png/jpg/gif) to 100kb, but allow PDF files to be up to 10mb

  • Limit customers to upload image files only whereas staff can upload pdf and office documents as well

  • Preventing abuse where users upload large zip files onto Confluence as their backup drive
