New or forgotten passwords

If you have forgotten your PDC Kerberos password there are several options on how to get a new one.


If you have forgotten your Kerberos password you will not be able to acquire a Kerberos ticket. Without a valid Kerberos ticket you will not be able to login at PDC. If you get a message like:

Password incorrect or preauthentication failed

when getting your Kerberos ticket (for instance using kinit) that is an indication that you are typing an incorrect password and need to get a new password set. However, if you get the message:

kinit: krb5_get_init_creds: Client yourUsername@NADA.KTH.SE expired

your Kerberos principal has expired and you only need to ask PDC to renew your principal.

Getting a new password

PDC will never ask you to send us your password!

When contacting PDC regarding forgotten passwords, please supply your PDC username. Also, preferably contact us using the e-mail you specified in your original account application, or, the address set in your .forward at PDC.
