Make sure that all vCenter Servers in a Linked Mode group are registered to the same vCenter Single Sign On server.
What does that mean suppose i have 3 site and 3 vcenter connected in a linked mode so during installation i need to install SSO in ONE location ONLY.
Suppose. I have 3 sites. I need to manage the 3 instances of vCenter (5.5) using linked mode but was wondering if I only installed the first site using simple install method (which includes the installation of SSO) then on the 2nd site I pointed the 2nd vCenter server back to the first instance of SSO (i.e not install SSO on the 2nd site) and same is for 3rd site as well. then only it will work ?
