There may be different reasons.
- You were exmatriculated or your employment has ended. In that case you are no longer entitled to use the IT infrastructure of the University.
- Your account was locked due to frequent use of an incorrect password. If your password was wrongly entered multiple times your account is locked for 30 minutes. After that you can log into your account by entering the correct password. Incorrect logins are often a result of capslock or the keyboard language being set wrong.
- There may be uncertainties regarding documents or payment for the Students’ Office. Your account is deactivated, if payments weren’t performed or your documents were incomplete. Please refer to the Students’ Office. After successful clarification the Students’ Office will reenable your account.
- Your password may contain unsupported special characters. This may be causing you to be able to log in to certain services, but not others. Please change your password by using the “Change password” feature under “Services” and try again.
