SP Unique Permissions
SP Unique Permissions is a script that will loop through all site collections in a web application, within sub sites, lists, libraries, folders and documents, and will list all the entities that have unique permissions with links to their administration pages
in a .csv file along with some info about these entities.
When clicking on the link, the user will be presented with the settings page in SharePoint for that entity (site, list, folder, item, document) detailing what permissions were given for it.
NOTE: The user that needs to run this script has to have access to all site collections inside the web application.
