I have received a letter/email with my ULCN account details. What is ULCN and what can I do with it?

As a student of Leiden University you are provided with a student account (ULCN account) that allows you to access a variety of systems such as uMail, uSis, Blackboard and library catalogues, as well as the physical workstations within the university. You must first activate your new account via uAccess before you can use it.
