When you submit a job to RSM from a client application such as Workbench, you select an RSM queue for the job. Each RSM queue is associated with a configuration defined in RSM, and each configuration has user accounts associated with it. When an RSM queue is selected in the client application, RSM pre-validates the account credentials associated with that queue. If credentials have not yet been cached in RSM, RSM will prompt you to specify them, and cache them for future job submission.
