I found this from

I would like to figure out how to do this gpedit.msc+AD+gpc+gpt magic for
win2k/xp with linux+samba(2.2/3.0/tng)+openldap and is it possible at all?


Although GPOs provide significantly more policy features than NT 4.0 System
Policy provides,
GPOs are stored and processed differently than NT 4.0 System Policy is. In
NT 4.0, the System
Policy file (often called ntconfig.pol) is stored in the Netlogon share on
domain controllers
within an NT 4.0 domain. When an NT 4.0 user logs onto a workstation in an
NT 4.0 domain,
the system reads the System Policy file from the Netlogon share, then sets
registry values that are
specific to a computer, user, or user group according to the policy file. NT
4.0 allows only a
single policy file to be processed at a given time. NT 4.0 System Policy
could apply to a specific
computer (or all computers), a specific user (or all users), or an NT 4.0
domain global group.
In contrast, GPOs are composed of two parts: the Group Policy Container
(GPC), which is stored
within Active Directory (AD), and the Group Policy Template (GPT), which is
stored within the
replicated SYSVOL folder on all AD domain controllers in a domain. Whereas
System Policy is
processed only when a user logs onto an NT 4.0 workstation, GPOs are
processed at both
machine startup (at which point machine-specific policy is processed) and
user logon (at which
point user-specific policy is processed). Again, in contrast to System
Policies, you can define a
virtually unlimited number of GPOs within an AD domain (though
practically speaking, large
numbers of GPOs will take a long time to process). And, whereas System
Policies apply to
individual users, individual computers, and NT security groups, GPOs are
processed only by AD
users and computers. However, AD security groups composed of either machines
or users can
filter GPOs' effects. This filtering capability, in conjunction with the
ability to have multiple
GPOs processed by a given user or computer, can provide much greater policy
flexibility than is
available in NT 4.0. Figure 1.2 shows an example of how you can use security
groups to filter
the effects of a GPO.
