Users can log into any vCloud Director site in which there is an organization where they have a user account. This does not change even if the organization is an association member. If the user wants to make changes to the service at a single site they can log in through their tenant URL at that site. If the user needs to make changes in other member sites, they can still log into them separately, authenticating each time.

Because the vCloud Director user interface utilizes certificates for integrity and confidentiality, those certificates must contain the site’s FQDN. While this is not an uncommon practice, it can become complicated when there are other access routes into the service.
