You add users of the OU as members of the newly created shadow group and then apply the fine-grained password policy to this shadow group. You can create additional shadow groups for other OUs as needed More information: http://technet.microsoft.com/en-us/library/cc770394(WS.10).aspx

There is no corruption of AD schema if all the domain controllers try to make changes. This is one of the very important roles in FSMO roles infrastructure. Domain Naming Master - This role is not used very often, only when you add/remove any domain controllers. This role ensures that there is a unique name of domain controllers in environment. 2. Domain Roles Infrastructure Master - This role checks domain for changes to any objects. If any changes are found then it will replicate to another domain controller. RID Master - This role is responsible for making sure each securit
