When using the “Simple Install” to install a new vCenter setup, you might encounter the following error when trying to register the vCenter server to the Web interface:

The vSphere Web Client Administration Tool only supports registration of vCenter Server version 5.0. For newer versions, the vCenter Server system must be registered with the Lookup Service to allow the vSphere Web Client to discover the system.

To resolve this, follow these steps:

  • Log in to the vSphere Web client as the admin account (admin@System-Domain) you created during the vCenter server installation
  • Browse to “Administration -> SSO Users and Groups”
  • Browse to the “Groups” tab and click on “__Administrators__”
  • Click “Add Princilpals”
  • Select our vCenter server as the identity source and add the user “Administrator” to the list

Then login as “Administrator” in to the vSphere Web client, you should see the vCenter server listed in the objects. No further registration needed.
