Note:  If you log in to the GUI via a node that is the configuration node, you get an  additional option  Service Assistant Tool , as shown in Figure 5-2. Clicking this button  takes you to the service assistant, rather than the cluster GUI. It is preferable for each user to have their own unique account. The default user accounts  should be disabled for use or their passwords changed and kept secured for emergency  purposes only. This approach helps to identify personnel working on the systems and track all  important changes done by them. The  Superuser  account should be used for initial  configuration only.
