NAME
kpasswd - change a user's Kerberos password
SYNOPSIS
kpasswd [principal]
DESCRIPTION
The kpasswd command is used to change a Kerberos princi-
pal'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 suc-
cessfully 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 the system default 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 edu.mit.Kerberos file under the
current realm. If that is missing, kpasswd looks for the
admin_server entry, but substitutes 464 for the port.
