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 (Key Distribution
Center) 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 Changes the password for the Kerberos principal, principal. 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 invoking the kpasswd command.
Note
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, and substi-
tutes 464 for the port.
FILES
/etc/krb5.conf Kerberos configuration file.
