VMware Identity Manager is required for Workspace ONE deployments and must be configured to communicate with your Workspace ONE UEM console. This process is largely automated through the Workspace ONE UEM Getting Started experience in the UEM console. Consider using the Getting Started wizard before attempting to use the Workspace ONE application.
Only run the Getting Started wizard after the health API has passed and the load balancer (if you are using one) shows "green."
For a walkthrough of enabling VMware Identity Manager integration, the Workspace ONE application, and core Workspace ONE features, please see the Workspace ONE Quick Configuration Guide, available at docs.vmware.com.
