I've got group of users, they are also Authentized users. Then I have one folder called Public which permissions need to do:

  • Every user of group Users should be able to read all files in Public folder
  • Every user should be able to create new folders in Public folder
  • If user creates folder, no other user from group Users can modify files in this folder or delete this folder
  • Every user can change or delete only files and folders they created

How should I configure Security for this folder? I think this is pretty regular situation, but my configuration doesn't seem to work at all.


The key is to use the advanced permissions dialog as well as specifying the scope (apply to) of the permission change and also applying a permission set to the CREATOR OWNER of the folder:

First, to give everyone in the group read access to the whole tree:

On the properties of the "Public" folder:

Security Tab

Users: Read & Execute, List Folder Contents, Read

Advanced security tab

Verify the "Users" permission for "Read & execute" has "This folder, subfolders, and files." in the "Apply To" column. Users in this group should have read access to the entire tree.

After that, two access control entries, one for creating folders, and one for granting permission to those folders to the owner:

Add access control entry to allow users to create folders at the top level of "Public"

Name: Users, Apply to: This Folder Only, Permissions: Create folders (Allow)

Add access control entry that gives users full access to only the folders they create under "Public"

Name: CREATOR OWNER, Apply to: Subfolders and files only, Permissions: Full control (Allow)

Edit to add: Be aware that in order for this to work properly with folders that already exist in "Public", you will have to set the owner of those folders to the users who created them if those owner fields have been changed since creation. The CREATOR OWNER permission refers to whoever the owner of a folder is. New folders should automatically be fine.

Be sure to use the Effective Permissions wizard to verify that things are set up the way you want.
