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.

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.

Prerequisites

This VMware Validated Design sets the Certificate Authority service hierarchies on both Active Directory (AD) servers: the main domain dc01rpl.rainpole.local (root CA) and the subdomain dc01sfo.sfo01.rainpole.local (the intermediate CA).

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

  • Verify that the Certificate Authority Service role and the Certificate Authority Web Enrollment role are installed and configured on the 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-256 or higher on the certificate authority.

Procedure

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