Using Identity Manager, the Ticket Manager for Windows
Kerberos ticket manager software is designed to manage authentication
(identity verification) across multiple online services that recognize
the Kerberos protocol. To learn more, see "Getting
Started in a Kerberized Environment," and "Kerberos
Tickets and How They Work."
This document provides instructions for:
Starting the Kerberos for Windows
Ticket Manager software
To start the Ticket Manager software, select the Ticket Manager program Windows Identity Manager
from the Start menu under Programs - Kerberos Utilities. The Identity Manager dialog
box will be displayed.
Getting a Kerberos Ticket
You will need to obtain a Kerberos Ticket-Granting Ticket (TGT),
or "master ticket," only once per computing session. By
default, this ticket is valid for ten hours. You will need to get
a new ticket after restarting or logging out on your machine, after
destroying existing tickets, or if you allow a ticket to expire.
To obtain a Kerberos ticket:
-
Start the Identity Manager application. A window is displayed
with No Tickets/Tokens listed.
-
Choose Action from the menu bar, then select
Get Ticket(s) from the pulldown menu.
-
When the Initialize Ticket window appears,
enter your PennKey, then click the OK
button.
-
Type your password and then click the OK
button.
Note: Kerberos passwords are case-sensitive. No text
will appear, nor will you see any cursor movement in the password
box as you type your password.
-
When your PennKey and password are successfully authenticated,
you will be given a Kerberos ticket-granting ticket (TGT). In
the Identity Manager application window you will see the Kerberos icon
followed by your Kerberos username. Click on the plus
sign to the left of your Kerberos username to see your
current tickets.
Note: The current version of Identity Manager displays
your active tickets in both Version 4 and Version 5 of Kerberos.
Since we will be using Version 5 at Penn, you will notice that
the wide ticket labeled "Version Four Kerberos" is
grey in color. This color signifies inactivity. The color codes
for the wide tickets can help you determine the status of your
Kerberos session:
grey
= no active tickets
green
= active tickets with over 15 minutes remaining
yellow
= active tickets which will expire within 15 minutes
red
= expired ticket
- Close (or minimize) the Leash32 window / application.
Important Note: Exiting Leash32
does not automatically destroy your existing tickets. Your Kerberos
ticket gives you, or anyone who uses your computer, access to
all Kerberized campus services to which you have access. Do not
leave your computer without manually destroying
your Kerberos tickets.
Renewing a Kerberos Ticket
-
Open the Identity Manager application.
-
Choose Action from the menu bar, then select
Renew Ticket(s) from the pulldown menu.
- The Initialize Ticket window appears. In the text field under
Enter your username, the current primary user's
full Kerberos principal (e.g. "janedoe@UPENN.EDU") should
appear. Click the OK button to accept, or simply
enter the PennKey of another user to change the username.
- A new, blank text field appears under Enter your password.
Enter your password and click the OK button to
the right.
- If your renewal is successful, the remaining time listed in
the Kerb-5 Ticket Life status area in the lower
right corner of the Leash32 window will have increased to the
length of a full new session.
Destroying a Kerberos Ticket
To prevent others from using your account information from your
computer, be sure to destroy any Kerberos tickets before leaving
your computer. You will need to obtain new tickets to gain access
using Kerberized clients.
To destroy your tickets:
-
Open the Identity Manager application.
-
Choose Action from the menu bar, then select
Destroy Ticket(s) from the pulldown menu.
-
Leash32 warns you that it will destroy your tickets. Click
the OK button.
- Confirm that you have no tickets by looking at the Identity Manager
list window. A minus sign should appear to the
left of your Kerberos username.
Note: You cannot selectively destroy
some tickets while preserving others. Destroying tickets is an "all-or-nothing"
action.
Quitting the Ticket Manager
To quit the Ticket Manager, select Exit from the
File menu.
Important Note: Exiting
Identity Manager does not automatically destroy your existing tickets. Your
Kerberos ticket gives you, or anyone who uses your computer, access
to all Kerberized campus services to which you have access. Do not
leave your computer without manually destroying
your Kerberos tickets.
Changing Your Kerberos/PennKey
Password
To change your Kerberos/PennKey password:
-
Open the application.
-
Choose Action from the menu bar, then select
Change Password from the puldown menu.
-
Enter your PennKey, then click the OK button.
-
Type your old password. Click the OK button.
-
Type your new password. Click the OK button.
-
Type your new password again to confirm you typed it correctly
the first time. Click the OK button.
Your Kerberos/PennKey password is now changed.
