A method and system for implementing policy by accumulating policies for a policy recipient from policy objects associated with a hierarchically organized structure of containers, such as directory containers (sites, domains and organizational units) that includes the policy recipient. Based on administrator input, policy settings for the policy recipient may be accumulated into a specific order by inheriting policy from higher containers, which may enforce their policy settings over those of lower containers. Policy that is not enforced may be blocked at a container. The result is an accumulated set of group policy objects that are ordered by relative strength to resolve any policy conflicts. Policy may be applied to a policy recipient by calling extensions, such as an extension that layers the policy settings into the registry or an extension that uses policy information from the objects according to the ordering thereof. Linking of group policy objects to one or more containers (e.g., sites, domains and organizational units) is provided, as is exception management. The effects of group policy may be filtered based on users' or computers' membership in security groups.
