The vCenter Simple Install process installs vCenter Single Sign-On, the Inventory Service, and vCenter Server on one system. The account you use when you run the Simple Install process affects which users have privileges on which components.

When you log in as a domain account user or local account user to install vCenter Server using vCenter Simple Install, the following behavior occurs upon installation.

By default, users in the local operating system Administrators group can log in to the vSphere Web Client and vCenter Server. These users cannot configure Single Sign-On or view the Single Sign-On management interface in the vSphere Web Client.

By default, the vCenter Single Sign-On administrator user is admin@System-Domain. This user can log in to the vSphere Web Client to configure Single Sign-On and add accounts to manage Single Sign-On if necessary. This user cannot view or configure vCenter Server.

If you are logged in as a domain account user, the default Active Directory identity sources are discovered automatically during vCenter Single Sign On installation. If you are logged in as a local account user, Active Directory identity sources are not discovered automatically during vCenter Single Sign On installation.

The local operating system (localos or hostname) users are added as an identity source.
