If the optional parameter principal is not used, kpasswd uses the
principal name from an existing cache if there is one. If not, the principal
is derived from the identity of the user by invoking the kpasswd
command.
kpasswd prompts for the current Kerberos password that is used to
obtain a changepw ticket from the KDC for the user’s Kerberos REALM.If
kpasswd successfully obtains the changepw ticket, the user is prompted
twice for a new password to make the password change.
Use kpasswd for your MIT KDC server only, not for Microsoft 2000
KDC. Also, note that kpasswd only changes Kerberos passwords on the
KDC, not the UNIX password. Use the UNIX passwd command to
change your UNIX password on the /etc/passwd file.
SYNOPSIS
/usr/bin/kpasswd [principal]
REFERENCE
For kpasswd manpage, issue the following command:
shell%: man 1 kpasswd
