The course catalog can also be viewed if you are not logged in. However, if you are logged in to HohCampus , you must have selected a suitable role (e.g. "student", "staff member") in order to be able to view the course catalog, otherwise a message will appear saying "Fehlende Zugriffsberechtigung” (no access rights). You do not need to re-enter your login details there if you are logged in. Instead, select the appropriate role and go to the page again.
