<h6><a name="wsseccfaltpacl"></a>Configure the Web services client for LTPA token authentication</h6>
|
||
|
|
|
||
|
|
<p>When a client authenticates to WebSphere Application Server - Express, the credential that is created contains an LTPA token. You can configure a Web service to send the LTPA token when it calls a downstream Web service.</p>
|
||
|
|
|
||
|
|
<p><strong>Note:</strong> You can only configure client LTPA authentication for a Web service that calls another Web service. Do not attempt to configure LTPA from a pure client. For the downstream Web service to validate the LTPA token, the LTPA keys must be the same for both servers.</p>
|
||
|
|
|
||
|
|
<p>Do not configure the client for LTPA token authentication unless LTPA is the configured authentication mechanism for WebSphere Application Server - Express. For more information, see <a href="../sec/seccamec.htm">Configure the authentication mechanism</a> in the <em>Security</em> topic.</p>
|
||
|
|
|
||
|
|
<p>Perform the following steps to specify LTPA token authentication for your Web services client:</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li><p>Open the webservicesclient.xml file in the Web Services Client Editor of the WebSphere Development Studio Client for iSeries. For more information, see <a href="astk.htm">Configure your Web services application</a>.</p></li>
|
||
|
|
|
||
|
|
<li><p>Click the <strong>Security Extensions</strong> tab.</p></li>
|
||
|
|
|
||
|
|
<li><p>Expand the <strong>Request Sender Configuration --> Login Config</strong> settings.</p></li>
|
||
|
|
|
||
|
|
<li><p>Select <strong>LTPA</strong> as the authentication method.</p></li>
|
||
|
|
|
||
|
|
<li><p>Save the file.</p></li>
|
||
|
|
</ol>
|
||
|
|
|
||
|
|
<p>Next, perform the following steps in the Web Services Client Editor to configure how the LTPA information is collected:</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li><p>Click the <strong>Port Binding</strong> tab.</p></li>
|
||
|
|
|
||
|
|
<li><p>Expand the <strong>Security Request Sender Binding Configuration --> Login Binding</strong> settings.</p></li>
|
||
|
|
|
||
|
|
<li><p>Click <strong>Edit</strong> to view the login binding information and select <strong>LTPA</strong>. If <strong>LTPA</strong> is not listed, enter it as an option. The login binding dialog displays.</p></li>
|

|
