|
||
|
|
<div><p>Your application can request any of several optional security services. IBM<sup>®</sup> JGSS
|
||
|
|
supports several services.</p>
|
||
|
|
<p>The supported optional services are:</p>
|
||
|
|
<ul><li>Delegation</li>
|
||
|
|
<li>Mutual authentication</li>
|
||
|
|
<li>Replay detection</li>
|
||
|
|
<li>Out-of-sequence detection</li>
|
||
|
|
<li>Available per-message confidentiality</li>
|
||
|
|
<li>Available per-message integrity</li>
|
||
|
|
</ul>
|
||
|
|
<p>To request an optional service, your application must explicitly request
|
||
|
|
it by using the appropriate request method on the context. Only an initiator
|
||
|
|
can request these optional services. The initiator must make the request before
|
||
|
|
context establishment begins.</p>
|
||
|
|
<p>For more information about optional services, see Optional Service Support
|
||
|
|
in Internet Engineering Task Force (IETF) RFC 2743 <a href="http://www.ietf.org/rfc/rfc2743.txt" target="_blank">Generic Security Services Application Programming Interface
|
||
|
|
Version 2, Update 1 </a> .</p>
|
||
|
|
<p><strong>Example: Requesting optional services</strong></p>
|
||
|
|
<p>In the following example, a context (fooContext) makes requests to enable
|
||
|
|
mutual authentication and delegation services: </p>
|
||
|
|
<pre> fooContext.requestMutualAuth(true);
|
||
|
|
fooContext.requestCredDeleg(true);</pre>
