Go to LDAP and check if your username is in the list (in the member rows).

• If your username is not in the list, then you enter the wrong password or you have not configured your network properly. You can change your password here: I have forgotten my MIF e-Identity Login and Password
• If your username is in the list means that your user is blocked because you have violated the MIF computer network usage rules. You have been informed of the violation by VU e-mail. To unblock your user, you must submit a written explanation to the MIF Vice Dean of IT.
