2. Save the configuration for WebSphere to have the generated keys stored in the WebSphere configuration; they will appear in the security.xml file. 3. Re-open the LTPA configuration page. 4. Specify the Key File Name which is the name of the file where LTPA keys will be stored when you export them. You need to export the keys in order to enable Single Sign-On on another server. Specify the full path name for the key file. We have used c:\WebSphere\Appserver\etc\SSO_ltpakeys. 5. Click Export Keys. Keys that have been exported in our scenario are presented in the example below. Example 10-1 Contents of the key file generated from WebSphere LTPA panel #IBM WebSphere Application Server key file #Tue Aug 13 18:25:07 EDT 2002 com.ibm.websphere.CreationDate=Tue Aug 13 18\:25\:07 EDT 2002 com.ibm.websphere.ltpa.version=1.0 com.ibm.websphere.ltpa.3DESKey=FDspFou4xxe1m4Il84JmAk+EXLb1QclZp7ji+BJPSDM\= com.ibm.websphere.CreationHost=wassrv01 com.ibm.websphere.ltpa.PrivateKey=9qo7ytSCbTf/62bvAyExobRikGAwF4vE/vKnKe7K80eJa /jUoiAtyeo6rQumiUw/otwCBSaGWWvAHAwpTKR3CP7oJm4CAxyj0UVNF2B2iSZspH+ekZ+fS62Amp64 HT+ppljshfmyjX4WZAOxRQdKpvHvX3BUMU1BjuRnlpQqp2Pov/VlBqpnSJI5vcLRrXZDCNUEA4Kd0CH cKyq5H22Iox4PiZ4rvpZ5UCXdjxfcA0rUbw+5KK1eZdVQLrcxHb/ufBQ51RrA6m2R8PCZua26RUOJwi x1Y0JpGBuwKNeKDCq/pY4l70K4nkyOEXrq7EBl0VkhtC7JEsR4o5Mbc1JSbuyCJsRamjgX5/plEFZSB HE\= com.ibm.websphere.ltpa.Realm=dirsrv01.itso.ibm.com\:389 com.ibm.websphere.ltpa.PublicKey=AO/uOSd3vL4zo7VUN3k8VSw9F+zpgwbRnDHmi8G8gmm5Tb CKGonK4Hl+gQ9dzSDNgkDJ3BWYJEkrCj77oZsI4RCZZk1RexDqLByEO9ffR/WyT7PR4FaMMFaZo0Iha DX3GyF3yHov6l3/DcsrvYCLgO3Fc+SPsX/QnHPDQOXyKZ6lAQAB As you can see in the example, three types of keys have been generated for LTPA. ► The private key, used for the LTPA server to sign the LTPA token. ► The public key, used to verify the digital signature. ► A shared key, used to encrypt/decrypt those tokens. 10.6.4 Enabling LTPA authentication for WebSphere The following steps will show you how to enable LTPA for WebSphere Application Server. 1. Select Security -> Global Security in the Administrative Console. 2. Make sure that Active Authentication Mechanism is set to LTPA (Light weight Third Party Authentication). 254 IBM WebSphere V5.0 Security Handbook
In the previous steps, we assumed that the user registry is already configured for LDAP. Configuring the User Registry is covered in previous sections. LTPA also works with other user registries; only this example uses LDAP, but for Single Sign-On scenarios, you might want to use centralized user registries. Note: The generation of the LTPA keys must be performed when the LDAP server settings are configured; this guarantees that the LDAP hostname is present in the exported file, as shown in bold in Example 10-1 on page 254. Domino needs this information during the Web SSO Configuration Document creation process. 3. Save the configuration. Your WebSphere Application Server is now configured to use LTPA authentication mechanism. You will need to log out of the Administrative Console and restart the server in order for the changes to take effect. 10.7 JAAS configuration JAAS for WebSphere Application Server can be configured using the Administrative Console. JAAS provides the pluggable authentication mechanism for WebSphere. If you want to know more about JAAS, refer to 8.6, “JAAS” on page 204. 10.7.1 Application login information WebSphere allows you to configure the pluggable authentication module for your application server. 1. Launch the Administrative console then log in with administrative privileges. 2. Select Security -> JAAS Configuration -> Application Logins to get to the page show in Figure 10-16. Chapter 10.
