kpasswd(1)

     NAME
          kpasswd - change a user's Kerberos password

     SYNOPSIS
          kpasswd [principal]

     DESCRIPTION
          The kpasswd command is used to change a Kerberos principal's
          password.  Kpasswd prompts for the current Kerberos
          password, which 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
          the new password, and the password is changed.

          If the principal is governed by a policy that specifies the
          length and/or number of character classes required in the
          new password, the new password must conform to the policy.
          (The five character classes are lower case, upper case,
          numbers, punctuation, and all other characters.)

     OPTIONS
          principal
               change the password for the Kerberos principal
               principal.  Otherwise, kpasswd uses the principal name
               from an existing ccache if there is one; if not, the
               principal is derived from the identity of the user
               invoking the kpasswd command.

     PORTS
          kpasswd looks first for kpasswd_server = host:port in the
          [realms] section of the krb5.conf file under the current
          realm.  If that is missing, kpasswd looks for the
          admin_server entry, but substitutes 464 for the port.

     BUGS
          kpasswd may not work with multi-homed hosts running on the
          Solaris platform.
