Why and when to perform this task
This task is used to configure Lightweight Third-Party Authentication (LTPA). LTPA is a type of authentication mechanism in WebSphere Application Server security that defines a particular token format. The purpose of the LTPA token authentication is to flow the LTPA token from the first Web service, which authenticated the originating client, to the downstream Web service. Do not attempt to configure LTPA from a pure client. Once the downstream Web service receives the LTPA token, it validates the token to verify that the token has not been modified and has not expired. For validation to be successful, the LTPA keys used by both the sending and receiving servers must be the same.
Complete the following steps to specify that LTPA is authentication method. The authentication method indicated in these steps must match the authentication method specified for the client.

What to do next
After you specify the authentication method, you must specify the information that the server must validate. See Configuring the server to validate LTPA token authentication information for more information.
