SharePoint Permissions in 60 Seconds
SharePoint Permissions are almost, but not quite similar to those on an NTFS file share.
The big difference, is there is no “break inheritance and cascade”. Other than that, it works like this:
SharePoint can use its own groups, or Active Directory or Claims groups.
Every new Site Collection you create, you have to recreate and populate any groups you want to be consistent across your Tenancy.
If you can use AD or claims groups, it’s easier to manage.
In SharePoint you can permission: Sites, Libraries, Folders, Files, List Items and many more.
There are 33 Permissions that can be granted.
That’s everything from View, Open, and Delete Items,
to Manage Alerts, Customize Pages and Manage Permissions.
You can’t grant these directly.
Bundle them up into a Permission Level, and grant that instead.
To grant permission is to give a Person or Group a Permission Level on a Thing.
To do that you must Break Inheritance of permissions of the Site, Library, Folder, etc that you are granting permission on.
