The first step in certificate generation and replacement is setting up a Microsoft Certificate Authority template on the Active Directory (AD) servers for the region. The template contains the certificate authority (CA) attributes for signing certificates of VMware SDDC solutions. After you create the new template, you add it to the certificate templates of the Microsoft CA.


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

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

  • Verify that dc51lax.lax01.rainpole.local is the intermediate CA of the root CA dc51rpl.rainpole.local.

  • Use a hashing algorithm of SHA-256 or higher on the certificate authority.


  1. Log in to the following AD server by using a Remote Desktop Protocol (RDP) client.




    • If you use the intermediate CA, connect to dc51lax.lax01.rainpole.local.
