We are a Windows shop currently appalled by the money Microsoft charges for their user CALs on our domain controller.
We were wondering whether we could substitute a Windows domain controller with one running Linux.
It would have to be able to allow users access to our network of Windows servers, including an Exchange 2003 email server. In addition, users would have to be able to access shared directories and printers which would be hosted on the new Linux sever. Lastly, the Linux box would have to be able to replicate with active directory hosted on secondary domain controllers that are running Windows 2003 server.
