To change a principal's password use the kadmin change_password
command, which requires the "modify" administrative privilege (unless
the principal is changing his/her own password). The syntax is:
change_password [options] principal
The change_password option has the alias cpw.
change_password takes the following options:
For example:
kadmin: cpw david
Enter password for principal david@ATHENA.MIT.EDU: <= Type the new password.
Re-enter password for principal david@ATHENA.MIT.EDU: <= Type it again.
Password for david@ATHENA.MIT.EDU changed.
kadmin:
Note that change_password will not let you change the password to
one that is in the principal's password history.
