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
