You create a Microsoft Certificate Authority Template to contain the certificate authority (CA) attributes for signing certificates of VMware SDDC solution.

About this task

Creating a certificate authority template for this VMware Validated Design includes the following operations:

  1. Set up a Microsoft Certificate Authority template. 

  2. Add the new template to the certificate templates of the Microsoft CA. 


This VMware Validated Design sets the CA up on both Active Directory (AD) servers: the main domain dc01rpl.rainpole.local (root CA) and the Region A subdomain dc01sfo.sfo01.rainpole.local (the intermediate CA). Both AD servers are running the Microsoft Windows Server 2012 R2 operating system. 

  • Verify that you installed Microsoft Server 2012 R2 VMs with Active Directory Domain Services enabled.

  • Verify that тhe Certificate Authority Service role and the Certificate Authority Web Enrolment role is installed and configured on both Active Directory Server.

  • Verify that dc01sfo.sfo01.rainpole.local has been set up to be the intermediate CA of the root CA dc01rpl.rainpole.local.

  • Use a hashing algorithm of SHA-2 or higher on the certificate authority.


  1. Log in to the AD server by using a Remote Desktop Protocol (RDP) client as the AD administrator with the ad_admin_password password.
    • If you use the intermediate CA, connect to dc01sfo.sfo01.rainpole.local.

    • If you use only the root CA, connect dc01rpl.sfo01.rainpole.local.
