[Samba] Active Directory

[Adriatik Allamani]

Hello

For the moment I manage the user in the network with win 2000 Server.
I want to use an linux OS to manage the network? Is this possible.

So. How can I organize and configure the Cent OS to use it as Active
Directory Server, and to open all the existing users
there, and then to shut down the win2000 Server and to Activate the
CentOS as domain controller?

I want to use Red Hat Enterprise Linux 5.0.0. And Samba 4.0

Can someone help me in this?

Thanks
