Configure the client for identity assertion: specifying the method

We can configure identity assertion authentication. The purpose of identity assertion is to assert the authenticated identity of the originating client from a web service to a downstream web service. There is an important distinction between v5.x and v6 and later applications. The information in this article supports v5.x applications only used with WebSphere Application Server v6.0.x and later. The information does not apply to v6.0.x and later applications.

This task is used to configure identity assertion authentication. The purpose of identity assertion is to assert the authenticated identity of the originating client from a web service to a downstream web service. Do not attempt to configure identity assertion from a pure client. Identity assertion works only when we configure on the client-side of a web service acting as a client to a downstream web service.

In order for the downstream web service to accept the identity of the originating client (just the user name), supply a special trusted BasicAuth credential the downstream web service trusts and can authenticate successfully. Specify the user ID of the special BasicAuth credential in a trusted ID evaluator on the downstream web service configuration. See topics about trusted ID evaluators.

To specify identity assertion as the authentication method:

  1. Launch an assembly tool. For more information, see the related information on Assembly Tools.
  2. Switch to the Java EE 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 WS Extension tab, located at the bottom of the deployment descriptor editor within the assembly tool.

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

  7. Select IDAssertion as the authentication method. For more conceptual information on identity assertion authentication, see Identity assertion in a SOAP message.

  8. Expand the IDAssertion section.

  9. For the ID type, select Username. This value works with all registry types and originating authentication methods.

  10. For the trust mode, select either BasicAuth or Signature.

See Configure the client security bindings using an assembly tool for more information on the web services client editor within the assembly tool.

After we specify identity assertion as the authentication method used by the client, specify how to collect the authentication information. See Configure the client for identity assertion: collecting the authentication method for more information.
