BSD/Linux as SDC to Windows server PDC
I've seen tutorials about how to set up an OpenBSD box as a PDC, but I can't seem to find any information about setting it up as a secondary to a Windows Server PDC.
We have a windows server based PDC in our network, which works fine for local machines. However, once you get to our outstations, the performance stinks. We would like to set up a secondary domain controller out there, so they can have a local server, but the locations aren't large enough to justify the expense of getting another windows server box. Is there some way I can utilize an OpenBSD or Linux box to fill this role, while talking back to the primary Windows server to get it's user accounts and the like? Thanks.
