You can direct one or more vCenter Server Appliances to use the vCenter Single Sign On instance of a single vCenter Server Appliance. This action makes all the vCenter Server instances accessible by the vSphere Web Client of each vCenter Server Appliance.

You can also set a new vCenter Server Appliance to use an external vCenter Single Sign On instance when you run the vCenter Server Setup wizard for a newly deployed vCenter Server Appliance. See Download and Deploy the VMware vCenter Server Appliance.

Deploy and configure the vCenter Server Appliance that has the target instance of vCenter Single Sign On. The target instance of Single Sign On must be hosted on another vCenter Server Appliance. It cannot be hosted on a Windows machine.

Verify that you have the URL of the Lookup Service for the target instance of vCenter Single Sign On.

1

Connect to the vCenter Server Appliance from a Web browser.

2

On the vCenter Server tab, click SSO.

3

Set the SSO deployment type to external.

4

Under Lookup service location, type the URL of the Lookup Service for the target instance of vCenter Single Sign On.

The new vCenter Server Appliance is configured to use the existing vCenter Single Sign On instance, and both vCenter Server instances are accessible by the vSphere Web Client of either vCenter Server Appliance.

You can repeat this procedure for multiple vCenter Server Appliances.
