OpenIDM 2.1 is now optimized for Internet scale with a discovery engine that is multi-threaded for performance and clustered for high availability. The
discovery engine enables the organization to synchronize users across many different data stores to ensure records are accurate and up to date in support of compliance and audit requirements. OpenIDM 2.1 embeds the Activiti Business Process and Workflow engine, a comprehensive, lightweight, and scalable solution, which meets industry-standard Business Process Model and Notation (BPMN) version 2.0 compliance, to support workflow-driven provisioning and identity management.
