Authentication and Access Control

The vSphere platform includes Platform Services Controller (PSC) that contains common infrastructure security services such as VMware vCenter single sign-on, VMware Certificate Authority, licensing, service registration, and certificate management services. The Platform Services Controller securely connects to LDAP or Microsoft Active Directory for identity management. It performs authentication and access control for administrators and applications that interact with the vSphere platform. You can deploy PCS as a load-balanced pair of appliances for each vCenter Server.
