• Obtaining Kerberos tickets

If you're not familiar with Kerberos authentication and terms such as Kerberos tickets, go to What Is Kerberos? to learn the concepts and terms.

To open the Kerberos application:

If you have installed the Mac OS X Kerberos Extras, go to the Applications folder, open the Utilities folder, and open the Kerberos icon.

Otherwise, you will need to navigate to the /System/Library/CoreServices directory (use the Go To Folder.. item in the Finder's Go menu), and open the Kerberos icon from there. (You may want to run the Kerberos Extras or make your own alias in a more convenient location.)

Result: The Kerberos application window is displayed.

1. Click on the Get Tickets button, choose Get Tickets from Tickets menu, or press <command>-N.

   Result: The Kerberos Login dialog box appears:

   The first time you use the Kerberos application to log in, the username box is blank. After that, by default the Kerberos Login dialog box displays the username of the person who last used it to log in.

2. Type your Kerberos username in the username box. (This is not necessarily the same as your Mac OS X username.)

   If you want to log in using a principal that contains an instance (if you are unfamiliar with this term, don't worry about it), enter a slash after your username and then type the instance, e.g. 'username/instance'. (This is the v5 style of specifying instances.)

3. Click once in the password box, or press the <tab> key, and type your password.
4. If you need to change realms, click once in the Realm field/popup list and choose the desired realm. If the desired realm is not present in the list, you can try typing it into the Realm field. This will only work if you have a Kerberos configuration file (edu.mit.Kerberos) that already includes the realm, or your site is set up for auto/DNS resolution of Kerberos realms. If neither of these are true, you should consult your system administrator for a proper Kerberos configuration file. You can see what realms are in the configuration file by using the Edit Favorite Realms feature of the Kerberos application.
5. Click on OK.

   Result: If authentication is successful, a ticket entry appears in the Kerberos application window:

   The Active User box indicates your Kerberos username, the realm for which your Kerberos tickets are valid, and the time remaining for which they are valid. An entry also appears in the ticket list.

   By default, Kerberos tickets are valid for 10 hours. You can shorten the duration for which tickets are valid at the time you log in. Refer to Specifying ticket lifetime when logging in for instructions on how to do this. You can also change the default ticket lifetime. Refer to Changing Preferences to find out how to do this.

   If you get a Kerberos error, it may be for any of the following reasons:

   • You've entered either your Kerberos username or password incorrectly. Try again, making sure that the CAPS LOCK key is not turned on.
   • You may not have authorization to log into the realm specified. If you're authorized to log into a different realm, refer to Adding and removing realms to make another realm available, and then choose it from the realms popup list when logging in.
   • The realm you specified does not have an entry in your configuration file and/or your site does not have auto/DNS configuration for that realm. Contact your site administrator.
   • There is a problem with your authorization for the realm you're using. Contact your site administrator.

   To see details about your tickets, click once on the triangle next to the username in the ticket list. See About the ticket list for more information.

   The Kerberos application allows more than one Kerberos user to log into the same Macintosh (note this is not the same as having two Mac OS X users logged in at the same time). An additional person can log in by completing steps 1 - 4.

   Each additional person who has logged in receives an entry in the ticket list:

   The active Kerberos user, i.e., the username whose tickets are used for authentication when you start a new Kerberos-using application, appears in the Active User box. This username is also underlined in the ticket list.

   To change active users, follow the procedure in the next section, Changing active users.

   If you log out of Mac OS X, all tickets for all Kerberos users will be destroyed.

   Once the duration of your tickets has ended, an 'expired' message appears:

   Specifying ticket lifetime when logging in

   If you want to change the length of time that your tickets are valid upon logging in, you can do it through the Kerberos Login dialog box. To do this,

   1. Click on the Get Tickets button, choose Get Tickets from Tickets menu, or press <command>-N.

      Result: The Kerberos Login dialog box appears.

   2. Click once on the Show Options button.

      Result: The Kerberos Login dialog expands, revealing the login options:

   3. Place the mouse pointer on the Ticket Lifetime slider and drag it to the desired time indicated above the slider.
   4. If you want, you can click on the Hide Options button to hide the login options, or you can just leave them always displayed (the Kerberos Login dialog will remember whether it was expanded or not the next time it's displayed).
   5. Enter your Kerberos username (if it's not already displayed) and password, then click on OK.

      Result:If your login is successful, you've obtained tickets that are valid for the lifetime you specified.

   The next time you log in, the lifetime of the tickets you obtain will be the same as the time you specified during the previous login, unless you repeat this procedure or force a constant default lifetime (see Changing preferences for instructions on how to do this).

6. You can change other Kerberos Login options here. See Changing preferences for more information about each option.

Below the Active User box and the Renew Tickets, Destroy Tickets, and Change Password buttons is the ticket list. The ticket list shows all the principals that are currently authenticated in the current Mac OS X user's session.

Each principal has a set of Kerberos tickets belonging to it. When you log in with Kerberos, you get a ticket-granting ticket which then allows you to get other tickets from other applications (also called services). Then for each application you run that requires Kerberos authentication, you get a service ticket.

By default, the principals and their tickets appear as a summary line in the ticket list. The summary lines are in bold text. Each summary line has three elements:

• The Kerberos versions supported by the realm the principal is authenticated in. This appears as '(v4/v5)', '(v4)', or '(v5)' before the principal. When you log in using Kerberos for Macintosh, it will attempt to get both Kerberos v4 and v5 tickets for your principal. However, not all Kerberos-using sites support both versions (v4 is becoming less common), or different realms at the same site may also support different versions, so you may see only one version listed.
• The username of the authenticated principal.
• The minimum remaining lifetime for the ticket-granting tickets belonging to the principal (displayed as hours:minutes). You receive one ticket-granting ticket for each Kerberos version the realm supports; these may have different expiration times (although Kerberos for Macintosh attempts to make them the same).

Instead of a time, you may see either 'expired' or 'not valid' in the Time Remaining column. 'Expired' means that your tickets have no time remaining and so are no longer valid; 'not valid' means they are no longer valid for some other reason, usually because your Mac's IP address has changed since you obtained the tickets. In either case, you need to renew your tickets (although Kerberos for Macintosh will also prompt you automatically to renew if you try to use a service requiring Kerberos tickets).

If you want to see details of tickets associated with each principal, click on the triangle at the left of the principal's summary line. The list will expand:

In the expanded list, you will see a list of the tickets (credentials) belonging to that principal. If the principal is authenticated for both versions of Kerberos, the tickets are grouped by version underneath a subheading for each version (see picture above).

If you always want the ticket list to display expanded entries, you can set the 'Always expand new ticket list entries' preference. See the Changing preferences section.

You can display even more detailed information about each ticket using the Ticket Info window. See the Displaying ticket information section.

The current, active user specifies which Kerberos username will be used for authentication when you work with an application that requires Kerberos authentication. If more than one Kerberos user is logged in, you may want to change the active user before using such an application.

Use one of the following techniques to change the active user:

• Click once on the boldfaced username line in the list that you want to be the active user, then click on the Make User Active button.
• Double-click on the boldfaced username line in the Tickets list.
• From the Tickets menu, choose Change Active User > username where username is the user you want to make active.
• Control-click on the Kerberos application's icon in the dock to display the Kerberos dock menu, and choose the username you want to make active from it.

Result: The new active user is displayed in the Active User box and also appears underlined in the ticket list.

To destroy tickets, select the boldfaced username line in the ticket list then click on the Destroy Tickets button, or choose Destroy Tickets from the Tickets menu.

Result: The ticket entry is removed from the ticket list. If other Kerberos users are logged in, their usernames remain in the ticket list and their tickets are valid for the remaining time indicated.

If your tickets have expired, or you want to extend the lifetime of existing tickets, you may want to renew your tickets. Professor lupo and his horrible pets mac os.

As of Mac OS X 10.3, Kerberos for Macintosh supports the 'renewable' property for tickets. If your site allows tickets to have this property, you can renew tickets up for a set amount of time without re-entering your password, as long as your current tickets are still valid (that is, haven't expired). By default, Kerberos for Macintosh tries to get tickets with the 'renewable' property; you can change this in the Kerberos Login dialog options or in the Kerberos application preferences.

In fact, by default, the Kerberos application will automatically attempt to renew your tickets if you leave it running (you can close the main window for convenience). Once half your ticket's lifetime has expired, if it has the 'renewable' property, the Kerberos application will automatically issue a renew request for it. It will keep doing this up until the renewable time limit. You can control this behavior by checking or unchecking the 'Auto-renew renewable tickets' checkbox in the Kerberos application preferences.

You can see if a ticket is renewable, and for how long, by using the ticket information window. See Displaying ticket information below.

If your tickets are expired, or you choose not to use the auto-renew feature and want to renew your tickets before they expire, or your tickets do not support the 'renewable' property, use the Renew Tickets command.

1. Click once on your boldfaced username line in the ticket list to select it.

   Result: The Renew Tickets button is activated.

2. Click on the Renew Tickets button, choose Renew Tickets from the Tickets menu, or press <command>-R.

   Result: Either your tickets are renewed to their full lifetime (if your ticket had the 'renewable' property and were not expired), or the Kerberos Login dialog box is displayed (if your tickets didn't have the 'renewable' property or they were expired).

3. If the Kerberos dialog was displayed, enter your password.
4. If you want to change the lifetime of the tickets you're obtaining, see Specifying ticket lifetime when logging in for instructions.
5. Click on OK.

   Result: The tickets' lifetime is extended either to the lifetime you specified when logging in or to the maximum duration set under Preferences.. (the default is 10 hours). To change the default tickets' lifetime, see Changing Preferences. If you are very close to the maximum renewable lifetime, your tickets will only be good for the time remaining until the end of the renewable lifetime, which may be shorter than your requested lifetime.

If you are interested in more information about your Kerberos tickets, the Kerberos application can display detailed information about each ticket by using the Get Ticket Info command. To display detailed ticket information:

1. Select a ticket entry in the ticket list of the Kerberos application's ticket list. (Note that you can only get info about individual ticket items - the non-bold lines. You may have to twiddle down the arrow next to the main entry to see the individual ticket items.)
2. Either double-click on the entry, or from the Tickets menu, choose Get Ticket Information, or press <command>-I.

Result: The Ticket Info window appears:

At the top of the ticket info window is the principal who owns the ticket, the service that the ticket was obtained for, and the Kerberos version of the ticket. The rest of the information is divided into several panes for easier reading:

• Times - The exact time the ticket was issued, the start and end time that the ticket is valid for, and when the ticket is renewable until (if applicable), all in local time. Also a status field to tell you if the ticket is valid, expired, or not valid for another reason.
• Flags (for v5 tickets only) - The properties, such as forwardable and renewable, of the ticket.
• IP Addresses - The IP addresses for which the ticket is valid. v5 tickets may be valid for multiple or no addresses, so you may see more than one or none listed, although typically you will only see none or one listed. v4 tickets can have no more and no less than one address, so you will only see one listed.
• Encryption - For v5 tickets, lists both the session key and service principal key encryption types of the ticket. For v4 tickets, lists the string to key type of the ticket
3. When you are done looking at the ticket information, you can close the Ticket Info window using its close box.

You can have more than one ticket info window open at once.

You can change your Kerberos password by using the Change Password.. command.

To change your password,

1. Click on the boldfaced username line in the ticket list to select it.

   Result: The Change Password.. button is activated:

2. Click on the Change Password.. button or choose Change Password.. from the Tickets menu.

   Result: The Kerberos Change Password dialog box appears with the name of the user selected previously at the top:

3. Enter the password you're using now in the 'Enter your old password' box.
4. Click once in the 'Enter your new password' box, or press the <tab> key, and type the new password.
5. Click once in the 'Enter your new password again' box, or press the <tab> key, and type the new password a second time, exactly as you typed in the previous step.
6. Click on OK.

   Result: Either you will receive a confirmation that your password has been changed, if you entered either your old password incorrectly or the entries for the new password don't match exactly, you'll get an error. You may also receive an error from the Kerberos server if you try to choose an insecure password.

   This password stays in effect until you change it again using either the Kerberos application or the equivalent procedure on another Kerberos client on another platform.

The Kerberos application's dock icon has several features to help you quickly determine the status of the active user's tickets and to manage your Kerberos tickets.

Graphical ticket status & time remaining indicator

In the dock icon, the color of the key in the dock icon changes to indicate the status of the active user's tickets. Below the key is a display of the time remaining in the active user's tickets in the form hours:minutes (the time remaining display can be turned off in the Preferences dialog or in the Kerberos dock menu). The possible states are:

Gold key: The active user has valid tickets.

Red key: The active user's tickets are near expiration (less than 5 minutes lifetime remain).

Black key: The active user's tickets have expired, or no tickets are in the cache. Time remaining is shown as '--:--' .

Indented key: The Kerberos application is not running.

You can close the ticket list window without quitting the Kerberos application, so that you can still have the dock icon showing without cluttering your screen with a window you don't always need open.

Kerberos Dock Menu

If you control-click (or click and hold down for a few seconds) on the Kerberos application's dock icon while the application is running, the Kerberos dock menu will appear:

(If the only option you see in the Kerberos Dock Menu is 'Show in Finder', the Kerberos application is not running.)

The Dock Menu items perform the following functions:

Kerberos - Brings the ticket list window to the front. (If the ticket list window is closed, this option will not be listed.) Other windows, such as any open ticket information windows, will also be listed and can be brought to the front by choosing them.

Display time remaining in icon - Turns on/off the display of time remaining of the active user's tickets in the dock icon (default is on).

Get Tickets.. - Displays the Kerberos Login dialog, allowing you to get tickets for a new user (or new tickets for an existing user).

Destroy Tickets - Destroys the active user's tickets (the active user is indicated by a checkmark next to the user's principal in the user list). If no users are authenticated, this option will be disabled.

Renew Tickets.. - Renews the active user's tickets (the active user is indicated by a checkmark next to the user's principal in the user list). If the tickets do not have the renewable property, will display the Kerberos Login dialog, otherwise, renewal will happen automatically. If no users are authenticated, this option will be disabled.

Active users (variable text) - These are the principals of the currently authenticated users. The active user is marked with a checkmark. You can change the active user by choosing another principal from the menu.

Keep In Dock - Retains the Kerberos application icon in the dock, even when the application is not running, for easy access.

Show In Finder - Opens the folder containing the Kerberos application in the Finder.

Hide - Hides, but does not quit, the Kerberos application.

Quit - Quits the Kerberos application.

A default Kerberos realm is specified by the edu.mit.Kerberos configuration file (as distributed from MIT, this realm is ATHENA.MIT.EDU). When using the Kerberos application to log in, by default the Kerberos username and password entered are checked for authorization in this area of the network. You can add other realms, as described in this section, and change which one Kerberos Login uses by default. (For instructions on how to change the default realm, see Changing Preferences.)

Other realms listed in the edu.mit.Kerberos configuration file can also be used for logging in, but must first be added to the list of 'favorite' realms which are displayed in the Kerberos Login dialog. You can do this one of two ways.

First, you can type the realm you want directly into the Realm field/popup in the Kerberos Login dialog. This will only work if the realm is already in your Kerberos configuration file, or if your site is set up for auto/DNS resolution of Kerberos realms. If you are unsure if either of these are the case, or you try to add a realm this way and it doesn't work, consult your site administrator.

Second, you can use the Edit Favorite Realms of the Kerberos application that provides the following options for making the other realms in the preferences available for use:

• You can add one or multiple realms from the edu.mit.Kerberos preferences file to the Favorite Realms List.
• If you want to keep the list of Favorite realms to the minimum that you need, you can remove realms from the Favorite Realms List.
• You can type in the name of a realm to be used directly. This should only be used for auto configuration/DNS realms; typing in the name of a realm that is not in the configuration file and does not have a auto/DNS configuration at your site will not work, as simply giving the name of a realm does not provide all the necessary information for that realm to be used by Kerberos for Macintosh. If you do not see a realm you want here and are unsure if there is a auto/DNS configuration for it, consult your site administrator.

For information on adding new realm information to the Kerberos preferences file, see the Kerberos Preferences on Mac OS X Documentation. Kerberos for Macintosh does not provide a GUI way to add this information. Generally you should not have to do this, consult with your site administrator first!

     Result: The selected realm is removed from the Favorite Realms list:

     NOTE: At least one realm is required in the Favorite Realms list.

   • Type the name of a realm with auto/DNS configuration into the 'Add realm that has auto configuration' field, and click on the Add button to the right of that field.
   • You can also rearrange the order of realms in the list by dragging them around in the Favorite Realms list.
3. When you have finished adding and/or removing realms, click on Done.

   Result:If you've added one or more realms, they are now available from the Kerberos Login dialog box. If you've removed any realms, they are no longer available for use unless you add them again later on.

   To find out how to change the default realm, refer to Changing preferences.

You can make certain customizations to the Kerberos application by using the Preferences.. command. These customizations also affect the Kerberos Login dialog anytime another application brings it up.

1. From the Kerberos (application) menu, choose Preferences..

   Result:The Preferences dialog box appears (see illustrations below).

2. The Kerberos preferences are divided into several groups, with a tab for each group. Click on the tab for the preferences you want to modify:
   • Ticket Defaults - preferences that control the default ticket options for the Kerberos Login dialog
   • Username Defaults - preferences that control the default username and realm options for the Kerberos Login dialog
   • Time Ranges - preferences that control the minimum, maximum, and default settings of the ticket lifetime and renewable lifetime sliders in the Kerberos Login dialog
   • Behavior - preferences that control the way the Kerberos application displays information and other behaviors
3. Make changes to any of the following:
   • Ticket Defaults:
     • Remember ticket options from last Kerberos login/Use these ticket options (default = 'Remember ticket options from last login'): This popup menu lets you chose whether to retain the ticket properies and lifetime options in the Kerberos Login dialog box after each time you log in, or to always use the options specified in the Preferences dialog each time. NOTE: Changes you make to these options only take effect the next time you obtain tickets. Any tickets that you currently have maintain the options and lifetimes that were set when you obtained them.
       • Ticket lifetime always (default=10 hours) (only applies if 'Use these ticket options' is selected): To change the duration for which tickets will be valid, place the mouse pointer on the Ticket Lifetime slider and drag it to desired time indicated above the slider.
       • Always get forwardable tickets (default=on) (only applies if 'Use these ticket options' is selected): Tickets that you've obtained on your machine are valid on another machine to which you are connecting. (We recommend that you leave this option turned on.) Only applies to Kerberos v5 tickets.
       • Always get addressless tickets (NAT mode) (default=on) (only applies if 'Use these ticket options' is selected): Request tickets that will not contain any IP addresses. This feature is required to use many Kerberos v5 services behind a NAT. Only applies to Kerberos v5 tickets.
       • Always get proxiable tickets (default=on) (only applies if 'Use these ticket options' is selected): Request tickets that are proxiable. Proxiable tickets are used by some Windows 2000 Kerberos services. Note that unlike the other options, you cannot enable or disable this option in the login dialog itself. You can only modify it here. Only applies to Kerberos v5 tickets.
       • Always get tickets renewable for (default = on) (only applies if 'Use these ticket options' is selected): Request tickets with the 'renewable' property, so that they can be renewed without re-entering your password as long as your existing tickets are valid. Tickets can be renewed in this way for the length of time specified by the slider (which defaults to 7 days). Your site may not allow you to get tickets with the renewable property, or may not allow them to be renewable for as long as you request.
• Username Defaults:
• Remember principal from last Kerberos login/Use this principal information (default = 'Remember principal from last login'): This popup menu lets you chose whether to retain the username, instance, and realm in the Kerberos Login dialog box after each time you log in, or to always use the options specified in the Preferences dialog each time.
  • Always use blank username (default) (only applies if 'Use this principal information' is selected): The username field will always be blank in the Kerberos Login dialog.
  • Always use this username (only applies if 'Use this principal information' is selected): The username field of the Kerberos dialog will always be the specified username. You can enter a username and instance pair here, it should be in v5 style (e.g. 'username/principal'). You can edit the username field to be something different for a single login, but it will always return to this username on next login.
  • Always use this realm (only applies if 'Use this principal information' is selected): The realm selected from this popup will always appear as the selected realm in the Kerberos Login dialog's realm popup. If the realm you want is not in the popup list, use the Edit Favorite Realms to add realms, then return to the Preferences dialog and choose the desired from the Realm popup list.
• Time Ranges:
  • Using the edit fields in this preferences panel, you can set the minimum and maximum range of the ticket lifetime and renewable lifetime sliders displayed by the Kerberos Login dialog. These settings only control the minimum and maximum lifetimes your Macintosh requests from the Kerberos server; the Kerberos server may not allow tickets longer or shorter than certain lifetimes, or not allow tickets longer or shorter than certain renewable lifetimes. Defaults are 10 minutes minimum ticket lifetime, 10 hours maximum ticket lifetime, 10 minutes miniumt renewable lifetime, 7 days maximum renewable lifetime.
• Behavior:
  • Auto-renew renewable tickets (default=on): When this option is checked, Kerberos.app will automatically renew any tickets that have the 'renewable' property once they reach half or less of their valid lifetime. You must leave the Kerberos application running for this option to be useful.
  • Display time remaining in dock icon (default=on): When this option is checked, the time remaining in the active user's tickets will be displayed in the Kerberos application's dock icon.
  • Always expand new ticket list entries (default=off): When this option is checked, the full list of your individual tickets displayed in the ticket list by default (as opposed to a summary of your tickets indicated by your username). See About the ticket list for more details.
  • After the Kerberos application is launched (window options) (default='Always open ticket list window'): This option controls whether the Kerberos application displays the ticket list window when the application is launched. You may not want the window displayed if you primarily use the dock icon and menu.
    • Always open ticket list window: The ticket list window will always be displayed when the Kerberos application is launched, regardless of its state when the application was last quit.
    • Never open ticket list window: The ticket list window will never be displayed when the Kerberos application is launched, regardless of its state when the application was last quit.
    • Remember if the ticket list window was last open: The ticket list window will be displayed when the Kerberos application is launched if it was open when the Kerberos application was last quit, and not displayed if it was closed when the application was last quit.
