In order to create a tenant, the administrator needs to access the super tenant and double click on the gearwheel. A panel with all tenants will appear. On the bottom right of the panel is a button for adding a tenant to the system.
Upon clicking on the 'Create new tenant' button a popup will appear. Under tenant name, the name of the tenant has to be entered. By clicking the 'OK' button the tenant will be added to the system and with it all necessary system accounts. The tenant can then be accessed via the login screen with tenantname/admin or simply by clicking on the tenant in the tenant list.
