If your user belongs to more than one tenant, then you will have an option called “Tenants” when clicking on your login name in upper right corner of the Portal. Clicking on this option will show a list of all tenants your user have access to:
You can switch between the different tenants by clicking the tenant you want to work in.
If your user has access to one tenant only, then you will see the name of this tenant instead of “Tenants”
Click “Edit” button to open the “set access filter” page. The button to the right on the filter will show when you hover it with the mouse:
The tenant Administrator can create new users from within the Administration module >> Users >> New.
When the new user has been created, go to Roles (still within Administration) >> select the role you want to add the new user to >> Edit >> add the new user to this role. The last step is to give the user a license (still within the Administration module). The user can now use this new user to log into this tenant.
