To deploy the set of default plug-ins when the Orchestrator server starts, the Orchestrator system must authenticate against an LDAP or vCenter Single Sign On server. You first specify the administrative credentials that Orchestrator uses with the plug-ins, and enable or disable plug-ins.
If you change the Orchestrator database after configuring and installing the default plug-ins, you must click the Reset current version link on the Troubleshooting tab. This operation deletes the install_directory\app-server\server\vmo\plugins\_VSOPluginInstallationVersion.xml file, which contains information about the version of the plug-ins already installed, and forces plug-in reinstallation.
Set up an LDAP or vCenter Single Sign On server and configure the Orchestrator authentication settings.
