correct. Then it trusts that the identity of the request is c_user, as specified in the LTPA token. 6. WebSphere sends output to WebSEAL. 7. WebSEAL sends the output to the client. WebSEAL does not send the LTPA cookie to the client, but rather the cookie is stored in WebSEAL’s LTPA cache. This is advantageous since LTPA tokens, if sent to the client over the Internet, could be decrypted over time. Because the LTPA signature never changes, intercepting LTPA cookies and cracking LTPA tokens would be an easy and effective way to breach an otherwise secure environment. Configuring an LTPA-enabled WebSEAL Junction The following procedure will describe the steps necessary to configure WebSphere to trust LTPA tokens that are issued by WebSEAL. This involves generating an LTPA key file on the WebSphere server, copying the key file to the WebSEAL server, and using the key file when configuring the WebSEAL junction. 1. On the WebSphere Administrative Console, click Security -> Authentication Mechanisms -> LTPA to see the LTPA configuration panel, as shown in Figure 12-5. 2. Change the password if necessary. Note: The first time that security is enabled with LTPA as the authentication mechanism, LTPA keys are automatically generated with the password entered in the panel. In this procedure, however, LTPA keys will be generated manually so that they can be immediately exported and copied to the WebSEAL server. 3. Click the Generate Keys button. 4. In the Key File Name field, enter the full path of a file on the WebSphere server where the key file should be placed. 5. Click Export Keys to create the exported key file. The LTPA key file is a text file which will look something like the one shown in Example 12-1.
