Configure the client for LTPA token authentication: specifying LTPA token authentication

 

To configure Lightweight Third-Party Authentication (LTPA) token authentication, specify LTPA token authentication. Only configure the client for LTPA token authentication if the authentication mechanism configured in WebSphere Application Server is LTPA.

 

Overview

There is an important distinction between V5.x and V6.0.x and later applications. The information in this article supports V5.x applications only that are used with WebSphere Application Server V6.0.x and later. The information does not apply to V6.0.x and later applications.

Use this task to configure Lightweight Third-Party Authentication (LTPA) token authentication. Only configure the client for LTPA token authentication if the authentication mechanism configured in WebSphere Application Server is LTPA. When a client authenticates to a WebSphere Application Server, the credential created contains an LTPA token. When a Web service calls a downstream Web service, you can configure the first Web service to send the LTPA token from the originating client. Do not attempt to configure LTPA from a pure client. LTPA works only when you configure the client-side of a Web service acting as a client to a downstream Web service. For the downstream Web service to validate the LTPA token, the LTPA keys on both servers must be the same.

Complete the following steps to specify LTPA token as the authentication method:

 

Procedure

  1. Launch an assembly tool. For more information on the assembly tools, see Assembly tools.

  2. Switch to the J2EE perspective. Click Window > Open Perspective > J2EE.

  3. Click Application Client Projects > application_name > appClientModule > META-INF.

  4. Right-click the application-client.xml file, select Open with > Deployment descriptor editor.

  5. Click the Extensions tab, which is located at the bottom of the deployment descriptor editor within the assembly tool.

  6. Expand the Request sender configuration > Login configuration section.

  7. Select LTPA as the authentication method. For more conceptual information on LTPA authentication, see Lightweight Third Party Authentication.

 

What to do next

After you specify LTPA token as the authentication method, specify how to collect the LTPA token information. See Configuring the client for LTPA token authentication: collecting the authentication method information for more information.
