Specifications

9 Enter the site name for vCenter Single Sign-On.
The site name becomes important if you are using vCenter Single Sign-On in multiple locations. Choose
your own name for the vCenter Single Sign-On site.
NOTE You cannot change the site name at a later time.
10 Review the installation options and click Install.
vCenter Single Sign-On is installed or upgraded.
After vCenter Single Sign-On is installed or upgraded, the following default identity sources and users are
available:
localos
All local operating system users. These users can be granted permissions to
vCenter Server. If you are upgrading, those users who already have
permissions keep those permissions.
vsphere.local
Contains all users who have administrator access to the vCenter Single Sign-
On server. Initially, only the user administrator is defined.
To add other identity sources, such as a native Active Directory (Integrated Windows Authentication)
domain or an OpenLDAP directory service, see “Add a vCenter Single Sign-On Identity Source,” on
page 104.
What to do next
Upgrade the vSphere Web Client. See “Install or Upgrade the vSphere Web Client,” on page 128.
Install or Upgrade the vSphere Web Client
The vSphere Web Client lets you connect to a vCenter Server system to manage your vSphere deployment
through a browser.
If an earlier version of the vSphere Web Client is installed, this procedure upgrades the vSphere Web Client.
NOTE vCenter Server 5.5 supports connection between vCenter Server and vCenter Server components by
IP address only if the IP address is IPv4-compliant. To connect to a vCenter Server system in an IPv6
environment, you must use the fully qualified domain name (FQDN) or host name of the vCenter Server.
The best practice is to use the FQDN, which works in all cases, instead of the IP address, which can change if
assigned by DHCP.
