Shadow Groups

-
http://trycatch.be/blogs/roggenk/archive/2007/07/18/active-directory-domain-services-fine-grained-password-policies.aspx

A shadow group is a global security group that is logically mapped to an OU to enforce a fine-grained password policy. 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

Flexibility Schema Operations Master FSOP

1. Forest Roles

Schema Master - As name suggests, the changes that are made while creation of any object in AD or changes in attributes will be made by single domain controller and then it will be replicated to another domain controllers that are present in your environment. 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 security prin…
