<h3><a name="secdureg"></a>Develop custom user registries</h3>

<p>WebSphere Application Server - Express security supports the use of custom registries in addition to LocalOS and LDAP registries for authentication and authorization purposes. A custom user registry is a user registry that you implement. You must implement the <a href="../program/apidocs/ae/com/ibm/websphere/security/UserRegistry.html">UserRegistry</a> <img src="api.gif" width="18" height="15" align="absbottom" alt="Go to API documentation"> interface that is provided by WebSphere Application Server - Express. A custom implemented user registry can support virtually any type of user registry, such as a relational database or a flat file. (You can use JDBC to connect to your custom user registry database.) The custom user registry provides considerable flexibility in adapting WebSphere Application Server - Express security to various environments where a user registry other than LDAP or LocalOS already exists.</p>
|
||
|
|
|
||
|
|
<p>Implementing a custom user registry is a software development effort. Use the methods defined in the UserRegistry interface to make calls to the desired registry to obtain user and group information. The interface defines a very general set of methods, so it can be used to encapsulate a wide variety of registries. For more information, see <a href="secdcurm.htm">UserRegistry interface methods</a>. A custom user registry can be configured as the active user registry when configuring WebSphere Application Server - Express global security.</p>
|
||
|
|
|
||
|
|
<p><strong>Note:</strong> Make sure that your implementation of the custom registry does not depend on any WebSphere Application Server - Express components such as data sources. Do not have this dependency because security is initialized and enabled prior to most of the other WebSphere Application Server - Express components during startup. For example, if your implementation uses a data source to connect to a database, use JDBC to connect to the database instead.</p>

<p>See these code examples for a simple implementation of a custom user registry:</p>
|
||
|
|
<ul>
|
||
|
|
<li><a href="secdcurj.htm">Example: UserRegistry.java file</a></li>
|
||
|
|
<li><a href="secdcurf2.htm">Example: FileRegistrySample.java file</a></li>
|
||
|
|
<li><a href="secdcurg.htm">Example: Groups.props file</a></li>
|

<li><a href="secdcuru.htm">Example: Users.props file</a></li>

<p>Perform these steps to develop a custom user registry:</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li><p>If you are not familiar with the concept of custom user registries, see <a href="seccust.htm">Custom user registries</a>. This topic explains each of the methods in the interface in detail.</p></li>
|
||
|
|
|
||
|
|
<li><p>Implement all of the methods in the interface except for the createCredential() method, which is implemented by WebSphere Application Server - Express.</p></li>
|
||
|
|
|
||
|
|
<li><p>Build your implementation.</p></li>
|
||
|
|
|
||
|
|
<li><p>To compile your code, you need the sas.jar and wssec.jar files in your classpath. For example:</p>
|
||
|
|
<pre>javac -extdirs /QIBM/ProdData/WebASE51/ASE/java/ext:/QIBM/UserData/Java400/ext:
|
||
|
|
/QIBM/ProdData/Java400/jdk14/lib/ext:/QIBM/ProdData/WebASE51/ASE/lib
|
||
|
|
-classpath /QIBM/ProdData/WebASE51/ASE/lib/sas.jar:
|
||
|
|
/QIBM/ProdData/WebASE51/ASE/lib/wssec.jar
|
||
|
|
com/ibm/websphere/security/FileRegistrySample.java</pre></li>

|
||
|
|
|
||
|
|
<li><p>Follow the steps in <a href="secccur.htm">Configure custom user registries</a> to configure your implementation using the WebSphere administrative console.</p></li>
