I have a multi-site Windows Server 2012 R2 AD domain.
Up until now we have been using individual office licenses.
At one specific site, we are testing an Office 365 implementation.
How do I integrate the Office 365 accounts into the on premise AD structure so that users don't have to memorize another set of credentials for Office 365?
I've run across some guides that seem to explain how to do this, but all involve setting up stuff on the Domain Controller. What is not clear to me is:
How do I set up this integration only for the site where we are doing the rollout? It only applies to that site and specific users at that site.
Which DC do I setup the integration at? The main DC (off-site) for the entire organization? The local DC at the site where we are rolling out Office 365? If I have two DCs on site (as is best practices), do I setup integration on both DCs?
This is another part that seems nebulous to me: we have one AD across several (international) sites, but each local office will purchase and maintain their own Office 365 accounts (here I'm talking about organizational accounts not user accounts) for their own local users for accounting and licensing reasons. Is it possible to integrate multiple organizational Office 365 into a single AD? How do you set it up so that the AD / Office 365 integration knows where to find the Office 365 account?
