You can use client-side load balancing and failover to improve the stability of your Active Directory plug-in configuration.

You can configure client-side load balancing when running the Add an Active Directory server and Update an Active Directory server workflows. Client-side load balancing is possible through the ServerSet Java class.


  1. Log in to the vRealize Orchestrator Client as an administrator.
  2. Navigate to Library > Workflows and enter the active_directory and configuration tags in the workflow search box.
  3. Run the Add an Active Directory server or Update an Active Directory server workflow.
  4. Select the Alternative hosts tab.
  5. From the drop-down menu, select Single Server, Round-Robin DNS Server, Round-Robin, or Failover.
    Option Description
    Single Server A server set implementation that connects to only one server.
    Round-Robin DNS Server

    A server set where server handles the case in which a given host name may resolve to multiple IP addresses. This server set does strictly require DNS server setup. The ordering mechanism for selecting an address is round-robin.

    Round-Robin A server set where load is distributed evenly between several directory servers. If a server is unavailable, the connection will move to the next server in the set.
    Failover A server set where server connections are established in order. This implementation can establish connections between separate server sets. Useful for providing high availability in complex environments.
  6. When you finish configuring the workflow run, click Run.
