The sm_ems command line interface may or may not run on a host different from the Adapter Platform Server. The clientConnect.conf file must be configured on the host running the command line interface. You should create a unique username and password that matches a user in serverConnect.conf and give that user All privileges. Typically, when using the command line interface from a third-party application, the username and password should not be prompted. However, if you want to run sm_ems manually, then prompting could be used. The VMware Smart Assurance System Administration Guide provides more information about security configuration.
