You need a ZEDAT account to log into the machines at the department. Once you have your account it needs to be whitelisted for usage at the physics department. This happens automatically for students, for new employees we need a note from your group (the group leader, IT coordinator or secretary).
ZEDAT deletes accounts shortly after people leave FU. If you have ongoing projects that make it necessary for you to keep your account with us, your account can be converted into a project account for the duration of the project. Talk to your group leader and us about converting your account in time.
