How to Configure HostExplorer 11.0.1.0 for Kerberos (Windows 2000/XP)

When you install HostExplorer 11.0.1.0 for Windows from the PennConnect CD or download it from the Supported Products site, pre-configured Penn Telnet profiles appear when you first launch HostExplorer. If, however, the Telnet destination you want does not appear in the HostExplorer Open Session window, you can use the instructions below to add the new Telnet site, then configure that profile for the Kerberos environment.

Notes:

• Before configuring HostExplorer 11.0.1.0 to run Telnet in a Kerberos environment, check with your Local Support Provider (LSP) to ensure your School, department, or administrative unit supports Kerberos.
  
• Ensure Kerberos client software (Leash32 2.6.5) is installed on your computer.

How to Configure a New Kerberos-enabled Telnet Profile

1. Start HostExplorer (Start → All Programs → Hummingbird Connectivity 2006 → HostExplorer). The Open Session window displays.
2. In the Open Session window, click the Hummingbird icon, which is the middle, multi-colored icon located in the upper-right corner of the window. The New Profile window displays.
3. In the Profile Name field, type the name or a description of the Telnet destination (for example, type Telnet to pobox.upenn.edu), then in the Host Name field at the bottom of the window, type the name of the host (for example, pobox.upenn.edu).
4. Click OK to return to the Open Session window.
5. In the Open Session window, under the Profile Name column, the Telnet site that you just created is highlighted. Right-click the highlighted telnet session, then select Properties from the dropdown list. The Session Profile window appears with the name you typed in the Profile Name field in step 3.
6. Under the Categories: column, click the plus symbol (+) beside the Security option to expand it, then select General to display the contents of the General tab in the right panel of the window.
7. In the General window, select the Kerberos radio button, but do not click OK yet.

   Note: In order to select the Kerberos option you must have already installed Leash32 2.6.x on your machine. If you have not installed Leash, quit HostExplorer, install Leash, and then return to HostExplorer.

8. Click the Kerberos tab at the top of the Session Profile window to display its contents.
9. In the Kerberos window, ensure the Kerberos Version field displays with Version 5, then click the Authentication checkbox to activate it. (Do not activate the Encryption checkbox).
10. You can now click OK to save your Kerberos configuration.
11. To connect to your Kerberized profile, you must first obtain a Kerberos ticket.

    Note: If you are using HostExplorer 11.0.1.0 or any Kerberized application for the first time, refer to the documents at How to Use Your PennKey for information on how to get set up and work in a Kerberized environment.
