Can Linux be used as primary or secondary domain controller on a windows server 2008 domain? I have used Samba to connect to a workgroup before but never to a domain. I know that Linux can function as a DC and also that it can join a 2008 domain. But I have not been able to find any information about if it can actually function as a DC on a 2008 domain. If anyone has any info or even better a link to a tutorial then please post it.
