Which Single Sign-On deployment mode should an administrator use for two 5.x vCenter
Servers configured with linked mode?
A.
Single Sign-On with Linked Mode
B.
Basic Single Sign-On
C.
Basic Single Sign-On with vCenter Server Heartbeat
D.
Multisite Single Sign-On
When to use the Multisite vCenter Single Sign-On server
•If you are using Linked Mode.
•If multiple vCenter Servers require the ability to communicate with each other.
•If you are required to have one single vCenter Single Sign-On server security domain throughout your organization.
In general SSO Multisite removes the risk of slow WAN based authentications however with all the manual steps required to maintain SSO synchronization, I would only recommend the use SSO Multisite if you are using vCenter Linked Mode of which SSO Multisite is a requirement.
