This technical note describes how to enable experimental support for OpenLDAP, PostgreSQL and MySQL if you want to use them with VMware vCenter Orchestrator. Orchestrator requires a working LDAP server in your infrastructure and a database that is separate from the standard VMware vCenter Server database. You can configure Orchestrator to work with the experimentally supported LDAP server and databases only for testing and evaluation purposes.
