+For StackStorm versions earlier than 3.3, Extreme Networks provided a commercial version of the StackStorm automation platform (EWC). EWC contained advanced features like RBAC, LDAP and the Workflow Designer. Since StackStorm 3.4 RBAC and LDAP are core-features of StackStorm itself and the FlowUI as part of ``st2web`` replaces the Workflow Designer. Therefore, the ``ewc`` role is no longer supported and the LDAP and RBAC backends are now configured and deployed via the ``st2`` role. The FlowUI does not require any configuration.
