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 cur-rent current
rent Kerberos password, which is used to obtain a changepw ticket from the KDC for the user's Ker-beros Kerberos
beros 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 princi-pal principal
pal 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 sub-stitutes substitutes
stitutes 464 for the port.
