Installing VMware vSphere Single Sign On (SSO) in Multi-site Mode

Posted by Sam McGeown

vmware logo VMware vSphere Single Sign On (SSO) can be installed in Multi-site mode to support local sign-on to vCenters that you want to be part of the same single sign on domain - for example, if you want to install Linked-Mode and have the advantage of a single pane of glass view, but can't risk using a single SSO instance across the WAN. In other words, from VMware's blog post:

Multisite deployments are  where a local replica is maintained at remote sites of the primary vCenter Single Sign-On instance. vCenter Servers are reconfigured to use the local vCenter Single Sign-On service and reduce authentication requests across the WAN. Multisite deployments do drop the support of single pane of glass views unless Linked Mode is utilized and multisite deployments are actually required to maintain Linked Mode configurations where roles, permissions and licenses are replicated between linked vCenter servers. Linked mode will re-enable single pane of glass views across multisite instances.
