Note: It might take some time before the changes you've made will take effect. The amount of time needed is influenced by the number of domain controllers, Global Catalogs and site replication schedules and intervals. On one domain with one site containing multiple domain controllers it might take up to 15 minutes before you can begin using these new permissions. On
single servers that are also DCs you can speed up the process by restarting the Information Store service.
