<h1 class="topictitle1">Configuring JGSS to use the native iSeries JGSS provider</h1>
<div><p>IBM<sup>®</sup> JGSS
uses the pure Java™ provider by default. You also have the option to
use the native iSeries™ JGSS
provider.</p>
<div class="section"><p>For more information about the different providers, see <a href="rzahajgsscfg15.htm">JGSS providers</a>. </p>
<p><strong>Software requirements</strong></p>
<p>The
native iSeries JGSS
provider must be able to access classes in IBM Toolbox for Java. For instructions about how to access IBM Toolbox
for Java,
see <a href="rzahajgsscfglinkjava.htm#rzahajgsscfglinkjava">Enabling the native iSeries JGSS provider to access IBM Toolbox for Java</a>.</p>
<p>Make
sure that you have configured the network authentication service. For more
information, see <a href="../rzakh/rzakh000.htm" target="_blank">Network
authentication service</a>.</p>
<p><strong>Specifying the native iSeries JGSS
provider</strong></p>
<p>Before you use the native iSeries JGSS provider with J2SDK, version
1.3, ensure that you have configured your server to use JGSS. For more information,
see <a href="rzahajgsscfg13.htm">Configuring your iSeries server to use JGSS with J2SDK,
version 1.3</a>. If you are using J2SDK, version 1.4 or subsequent versions,
JGSS is already configured.</p>
<div class="note"><span class="notetitle">Note:</span> In the following instructions, ${java.home}
denotes the path to the location of the version of Java that you are using on your server.
For example, if you are using J2SDK, version 1.4, ${java.home} is /QIBM/ProdData/Java400/jdk14.
Remember to replace ${java.home}in the commands with the actual path to
the Java home
directory.</div>
<p>To configure JGSS to use the native iSeries JGSS
provider, complete the following tasks: </p>
<p><strong>Adding a symbolic link</strong></p>
<p>To
add a symbolic link to the extension directory for the ibmjgssiseriesprovider.jar
file, on an iSeries command
line, type the following command (on a single line) and press <strong>ENTER</strong>:</p>
<pre> ADDLNK OBJ('/QIBM/ProdData/OS400/Java400/ext/ibmjgssiseriesprovider.jar')
NEWLNK('${java.home}/lib/ext/ibmjgssiseriesprovider.jar')</pre>
<p>After
you add a symbolic link to the extension directory for the ibmjgssiseriesprovider.jar
file, the extension class loader will load the JAR file. </p>
<p><strong>Adding
the provider to the security provider list</strong></p>
<p>Add the native provider
to the security provider list in the java.security file. </p>
</div>
<ol><li class="stepexpand"><span>Open ${java.home}/lib/security/java.security for editing.</span></li>
<li class="stepexpand"><span>Find the security provider list. It should be near the top of the
java.security file and should look something like: </span> <pre> security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.rsajca.Provider
security.provider.3=com.ibm.crypto.provider.IBMJCE
security.provider.4=com.ibm.security.jgss.IBMJGSSProvider</pre>
</li>
<li class="stepexpand"><span>Add the native iSeries JGSS provider to the security provider list
before the original Java provider. In other words, add com.ibm.iseries.security.jgss.IBMJGSSiSeriesProvider
to the list with a lower number than com.ibm.jgss.IBMJGSSProvider, then update
the position of IBMJGSSProvider. For example:</span> <pre> security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.rsajca.Provider
security.provider.3=com.ibm.crypto.provider.IBMJCE
security.provider.4=com.ibm.iseries.security.jgss.IBMJGSSiSeriesProvider
security.provider.5=com.ibm.security.jgss.IBMJGSSProvider</pre>
<p>Notice that the IBMJGSSiSeriesProvider became the fourth entry in the
list and IBMJGSSProvider became the fifth entry. Also, check that entry numbers
in the security provider list are sequential and that each entry increments
the entry number by only one.</p>
</li>
<li class="stepexpand"><span>Save and close the java.security file.</span></li>
