VMware Horizon uses your existing Active Directory infrastructure for user authentication and management. For added security, you can integrate VMware Horizon with two-factor authentication solutions, such as RSA SecurID and RADIUS, and smart card authentication solutions.
Active Directory Authentication Each Horizon Connection Server instance is joined to an Active Directory domain, and users are authenticated against Active Directory for the joined domain. Users are also authenticated against any additional user domains with which a trust agreement exists.
Using Two-Factor Authentication You can configure a Horizon Connection Server instance so that users are required to use RSA SecurID authentication or RADIUS (Remote Authentication Dial-In User Service) authentication.
Smart Card Authentication A smart card is a small plastic card that is embedded with a computer chip. Many government agencies and large enterprises use smart cards to authenticate users who access their computer networks. One type of smart card used by the United States Department of Defense is called a Common Access Card (CAC).
Using the Log In as Current User Feature Available with Windows-Based Horizon Client With Horizon Client for Windows, when users select Log in as current user in the Options menu, the credentials that they provided when logging in to the client system are used to authenticate to the Horizon Connection Server instance and to the remote desktop using Kerberos. No further user authentication is required.
