Deploying Office 2013 on Windows 2008 R2 Server(terminal Server), where do i put the licenses?

I am deploying Microsoft Office 2013 in a client server environment, and am confused about what types of licenses and where I apply the licenses to make sure every users on the terminal server(Windows Server 2008 R2) is validated and on authorized version of Office 2013. Could someone help guide me in this regards?
