.TH KPASSWD 1 "Kerberos Version 5.0" "MIT Project Athena"
.SH NAME
kpasswd \- change a user's Kerberos password
.SH SYNOPSIS
.B kpasswd
[
.B \-m
] [
.B \-l
language
] [
.B \-u
.IR username[/instance][@realm]
]
.SH DESCRIPTION
The
.I kpasswd
command is used to change a Kerberos principal's password.
If the
.I \-n
option is specified, a partially or fully qualified Kerberos principal may
be supplied. Otherwise, the principal name is derived from the identity
of the user invoking the
.I kpasswd
command.
The
.I \-l
and
.I \-m
flags may be specified to qualify how the administrative server is to issue
messages. The
.I \-l
flag specifies which
.I language
to issue messages in, while the
.I \-m
flag enables MIME-encoded messages. The support of these flags and the
interpretation of the
.I language
paramter is specific to the administrative server.
.PP
The
.I kpasswd
command prompts for the current Kerberos password, which is verified by the
Kerberos server. If the old password is correct, the user is prompted twice
for the new password. Success or failure is indicated by messages printed
out by
.I kpasswd.
.SH FILES
.TP 2i
/tmp/tkt_kpw_[uid]
the temporary credentials cache ([uid] is the decimal UID of the user) for
the lifetime of the password changing operation.
