After you have created the roles and assigned permissions to those roles, you need to allot these roles to various staff. To do so use the following link -
Super Admin --> Permissions --> Assign Roles
On this page from the drop down menu select the user / staff. As soon as you select that there will be a list of all the roles below along with the check box on the left and a radio button on the right. The initials in the bracket beside the role name indicate the campus they are for. Tick the check boxes for the roles you want to assign to that user. Make sure that the radio button is selected in front of one of the role assigned to that user. It means that as soon as the user logs into the portal that will be the module that will open up for him. If no radio button is selected for default role then user will have error while logging
