OpenUnison is a new approach to identity management.  OpenUnison combines web access management and provisioning services into a single system.  Utilizing an internal virtual directory, powered by MyVirtualDirectory, OpenUnison can combine identity data from several sources such as Active Directory, LDAP directories and relational databases.  OpenUnison combines most of the features of the commercial version of Unison, with the main difference being that OpenUnison is packaged as a J2EE application that is deployed into any J2EE container such as Tomcat or JBoss where as Unison is packaged as a stand alone service with a UI and management system.
