5 On the Select Features page, accept the defaults.
6 On the Select Role Services page, select Certification Authority.
7 Follow the prompts and finish the installation.
8 When installation is complete, on the Installation Progress page, click the Configure Active
Directory Certificate Services on destination server link to open the AD CS Configuration wizard.
9 On the Credentials page, click Next and complete the AD CS Configuration wizard pages as
described in the following table.
Option Action
Role Services Select Certification Authority, and click Next (rather than Configure).
Setup Type Select Enterprise CA.
CA Type Select Root CA or Subordinate CA. Some enterprises prefer two-tier PKI
deployment. For more information, see
http://social.technet.microsoft.com/wiki/contents/articles/15037.ad-cs-step-by-
step-guide-two-tier-pki-hierarchy-deployment.aspx.
Private Key Select Create a new private key.
Cryptography for CA For hash algorithm, you can select SHA1, SHA256, SHA384, or SHA512. For
key length, you can select 1024, 2048, 3072, or 4096.
VMware recommends a minimum of SHA256 and a 2048 key.
CA Name Accept the default or change the name.
Validity Period Accept the default of 5 years.
Certificate Database Accept the defaults.
10 On the Confirmation page, click Configure, and when the wizard reports a successful configuration,
close the wizard.
11 Open a command prompt and enter the following command to configure the CA for non-persistent
certificate processing:
certutil -setreg DBFlags +DBFLAGS_ENABLEVOLATILEREQUESTS
12 Enter the following command to ignore offline CRL (certificate revocation list) errors on the CA:
certutil -setreg ca\CRLFlags +CRLF_REVCHECK_IGNORE_OFFLINE
This flag is required because the root certificate that True SSO uses will usually be offline, and thus
revocation checking will fail, which is expected.
13 Enter the following commands to restart the service:
sc stop certsvc
sc start certsvc
What to do next
Create a certificate template. See Create Certificate Templates Used with True SSO.
