To allow a user to be able to delete User Profiles for orphaned account cleanup, I’ve added a user to the Farm Administrators group in SharePoint Central Administration and added them the Site Owners group with Full Control on a Site Collection. They can delete the User Profile in CA and view the User Information List (/_catalogs/users/simple.aspx) for the Site Collection. They cannot see the "Delete User from Site Collection" link as I can when they view the user detail (/_layouts/userdisp.aspx) from the User Information List.
What SharePoint permissions are required in order for a user to be able to delete a User Profile from the User Information List?
