For a vCenter Server Appliance, follow the instructions in the vCenter Server Appliance Configuration
documentation.
Note Active Directory (Integrated Windows Authentication) always uses the root of the Active Directory
domain forest. To configure your Integrated Windows Authentication identity source with a child domain
within your Active Directory forest, see VMware Knowledge Base article 2070433.
Select Use machine account to speed up configuration. If you expect to rename the local machine on
which vCenter Single Sign-On runs, specifying an SPN explicitly is preferable.
Note In vSphere 5.5, vCenter Single Sign-On uses the machine account even if you specify the SPN.
See VMware Knowledge Base article 2087978.
Table 22. Add Identity Source Settings
Text Box Description
Domain name FQDN of the domain name, for example, mydomain.com. Do not
provide an IP address. This domain name must be DNS-
resolvable by the vCenter Server system. If you are using a
vCenter Server Appliance, use the information on configuring
network settings to update the DNS server settings.
Use machine account Select this option to use the local machine account as the SPN.
When you select this option, you specify only the domain name.
Do not select this option if you expect to rename this machine.
Use Service Principal Name (SPN) Select this option if you expect to rename the local machine. You
must specify an SPN, a user who can authenticate with the
identity source, and a password for the user.
Service Principal Name (SPN) SPN that helps Kerberos to identify the Active Directory service.
Include the domain in the name, for example,
STS/example.com.
The SPN must be unique across the domain. Running setspn -
S checks that no duplicate is created. See the Microsoft
documentation for information on setspn.
User Principal Name (UPN)
Password
Name and password of a user who can authenticate with this
identity source. Use the email address format, for example,
jchin@mydomain.com. You can verify the User Principal Name
with the Active Directory Service Interfaces Editor (ADSI Edit).
Active Directory LDAP Server and OpenLDAP Server Identity Source Settings
The Active Directory as an LDAP Server identity source is available for backward compatibility. Use the
Active Directory (Integrated Windows Authentication) option for a setup that requires less input. The
OpenLDAP Server identity source is available for environments that use OpenLDAP.
If you are configuring an OpenLDAP identity source, see VMware Knowledge Base article 2064977 for
additional requirements.
