Understanding vSphere Domains, Domain Names, and
Sites
Each Platform Services Controller is associated with a vCenter Single Sign-On domain. The domain
name defaults to vsphere.local, but you can change it during installation of the first
Platform Services Controller. The domain determines the local authentication space. You can split a
domain into multiple sites, and assign each Platform Services Controller and vCenter Server instance to a
site. Sites are logical constructs, but usually correspond to geographic location.
Platform Services Controller Domain
When you install a Platform Services Controller, you are prompted to create a vCenter Single Sign-On
domain or join an existing domain.
The domain name is used by the VMware Directory Service (vmdir) for all Lightweight Directory Access
Protocol (LDAP) internal structuring.
With vSphere 6.0 and later, you can give your vSphere domain a unique name. To prevent authentication
conflicts, use a name that is not used by OpenLDAP, Microsoft Active Directory, and other directory
services.
Note You cannot change the domain to which a Platform Services Controller or vCenter Server instance
belongs.
After you specify the name of your domain, you can add users and groups. It usually makes more sense
to add an Active Directory or LDAP identity source and allow the users and groups in that identity source
to authenticate. You can also add vCenter Server or Platform Services Controller instances, or other
VMware products, such as vRealize Operations, to the domain.
