Abstract

A data store is distributed between a server and a client. The distributed data store includes global data. A transformation is applied to the global data to generate client-specific data based on the global data. The client-specific data is stored on the client which uses the client-specific data to perform tasks relating to the client-specific data.

Claims

1. A system comprising:

a server communicatively connected to a global data store, the global data store containing global data; and

wherein the server is operative to communicate with a client having a local data store that stores client-specific data generated by applying a transformation rule to the global data.

2. The system of claim 1, wherein the global data is global policy data.

3. The system of claim 2, wherein the client-specific data is client-specific policy data.

4. The system of claim 1, wherein the server is a domain controller.

5. The system of claim 4, wherein the transformation rule is stored in the global data store.

6. The system of claim 4, wherein the transformation rule is stored in the local data store.

7. A computer readable medium containing computer executable instructions which when executed by a computer perform a method of generating client-specific data, the method comprising:

defining global data;

defining transformation rules, each transformation rule including a scope, a priority, and a transformation;

applying the transformation rules to the global data in an order corresponding to the priority to generate client-specific data; and

storing the client-specific data on a client that is within the scope of the transformation rules.

8. The computer readable medium of claim 7, wherein applying the transformation rules to the global data is performed by a server.

9. The computer readable medium of claim 7, wherein applying the transformation rules to the global data is performed by a client after receiving the global data from a server.

10. The computer readable medium of claim 7, wherein applying the transformation rules to the global data is performed by a domain controller.

11. The computer readable medium of claim 7, wherein storing the client-specific data comprises storing the client-specific data in a registry of the client.

12. The computer readable medium of claim 7, wherein defining global data comprises defining a policy.

13. The computer readable medium of claim 7, wherein the transformation is selected from the group comprising:

an object override, an attribute override, a value exclusion, and a value extension.

14. The computer readable medium of claim 7, wherein applying the transformation rules comprises transforming a global set of administrators into a client-specific set of administrators.

15. The computer readable medium of claim 7, wherein storing the client-specific data comprises storing the client-specific data on a local data store of the client.

16. A directory service database comprising:

a first domain controller having a global data store containing global policy data, wherein the first domain controller distributes the global policy data; and

a second domain controller storing transformed global policy data, wherein the transformed global policy data is generated by applying a transformation rule to the global policy data.

17. The directory service database of claim 16, wherein the transformation rule comprises a scope, a priority, and a transformation.

18. The directory service database of claim 16, wherein the transformation rule defines an administrator to be added to a list of administrators and wherein the global policy data includes the list of administrators.

19. The directory service database of claim 16, further comprising a local data store communicatively connected to the second domain controller, the local data store containing transformation rules, wherein the transformation rules are applied to the global policy data by the second domain controller to generate transformed global policy data.

20. The directory service database of claim 16, wherein the transformed global policy data is used by the second domain controller to determine access rights.
