Sharepoint Server Farm add domain user

Hello,

I've created Sharepoint Farm (3 VMs, dc, sp and sql) with new option "Sharepoint Server Farm" in Azure Portal preview.

Everything works fine. Now I want to add another user to my AD in order to add it to the sharepoint later as site member, but i cannot find "Active Directory Users and Computers snap in" on my DC computer.

How can I add new user to my domain in this environment?

Thanks
