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,” on page 71.
Create Certificate Templates Used with True SSO
You must create a certificate template that can be used for issuing short-lived certificates, and you must
specify which computers in the domain can request this type of certificate.
You can create more than one certificate template, but you can configure only one template to be used at any
one time.
Prerequisites
n
Verify that you have an enterprise CA to use for creating the template described in this procedure. See
“Set Up an Enterprise Certificate Authority,” on page 70.
n
Create a security group in the domain and forest for the enrollment servers, and add the computer
accounts of the enrollment servers to that group.
