To change your password, run the kpasswd command. On strengthened UNIX systems running AFS, there are two kpasswd commands, one for AFS and one for Kerberos. Kerberos is implemented at Fermilab such that your AFS tokens will be obtained automatically. If you are unsure which kpasswd is being invoked, force the system to use the Kerberos version by running setup kerberos first. Kerberos password changed.

Please choose a password which is at least 10 characters long. New password does not have enough character classes. Please choose a password with at least 2 character classes.
