Quoting the release notes :
The VMware vCenter Orchestrator plug-in for Microsoft Active Directory allows organizations to automate the management of directory services tasks, particularly as they pertain to cloud provisioning use cases. For instance, the plug-in enables the automatic provisioning of vCloud Director organizations based on data retrieved from Active Directory. The plug-in also includes many administrative actions related to computers, organizations, user groups, and users, such as resetting passwords or adding users to a user group. The drag-and-drop workflow designer of vCenter Orchestrator allows you to easily assemble these actions into higher-level workflows to automate repetitive Active Directory administrative tasks.
For those familiar with older versions of vCO there was a Microsoft plug-in that was deprecated including Active Directory and WMI functionalities. The new vCenter Orchestrator Plug-in for Microsoft Active Directory covers only and more extensively the Active Directory functionality with adding support for multi-domain and password changes.
