Geoff Rehmet 60643d379b Initial import of eBones.
(Including all changes for FreeBSD - importing the original eBones distribution
would be too complex at this stage, since I don't have access to Piero's 
CVS.)
(If you want to include eBones in your system, don't forget to include
MAKE_EBONES in /etc/make.conf.)
(This stuff is now also suppable from braae.ru.ac.za.)

Bones originally from MIT SIPB.
Original port to FreeBSD 1.x  by Piero Serini.
Moved to FreeBSD 2.0 by Doug Rabson and Geoff Rehmet.
Nice bug fixes from Doug Rabson.

.TH KINIT 1 "Kerberos Version 4.0" "MIT Project Athena"
.SH NAME
kinit \- Kerberos login utility
.SH SYNOPSIS
.B kinit
[
.B \-irvl
]
.SH DESCRIPTION
The
.I kinit
command is used to login to the
Kerberos
authentication and authorization system.
Note that only registered
Kerberos
users can use the
Kerberos
system.
For information about registering as a
Kerberos
user,
see the
.I kerberos(1)
manual page.
.PP
If you are logged in to a workstation that is running the
.I toehold
service,
you do not have to use
.I kinit.
The
.I toehold
login procedure will log you into
Kerberos
automatically.
You will need to use
.I kinit
only in those situations in which
your original tickets have expired.
(Tickets expire in about a day.)
Note as well that
.I toehold
will automatically destroy your tickets when you logout from the workstation.
.PP
When you use
.I kinit
without options,
the utility
prompts for your username and Kerberos password,
and tries to authenticate your login with the local
Kerberos
server.
.PP
If
Kerberos
authenticates the login attempt,
.I kinit
retrieves your initial ticket and puts it in the ticket file specified by
your KRBTKFILE environment variable.
If this variable is undefined,
your ticket will be stored in the
.IR /tmp
directory,
in the file
.I tktuid ,
where
.I uid
specifies your user identification number.
.PP
If you have logged in to
Kerberos
without the benefit of the workstation
.I toehold
system,
make sure you use the
.I kdestroy
command to destroy any active tickets before you end your login session.
You may want to put the
.I kdestroy
command in your
.I \.logout
file so that your tickets will be destroyed automatically when you logout.
.PP
The options to
.I kinit
are as follows:
.TP 7
.B \-i
.I kinit
prompts you for a
Kerberos
instance.
.TP
.B \-r
.I kinit
prompts you for a
Kerberos
realm.
This option lets you authenticate yourself with a remote
Kerberos
server.
.TP
.B \-v
Verbose mode.
.I kinit
prints the name of the ticket file used, and
a status message indicating the success or failure of
your login attempt.
.TP
.B \-l
.I kinit
prompts you for a ticket lifetime in minutes. Due to protocol
restrictions in Kerberos Version 4, this value must be between 5 and
1275 minutes.

option has not been fully implemented.
