Netscape LDAP Service Provider for JNDI (09-15-99)</h2>
The Netscape LDAP service provider for JNDI implements the JNDI DirContext
interface. It is implemented as a layer on top of the Netscape Directory
SDK for Java (ldapjdk.jar). While the ldapjdk uses the LDAP connection
as the primary abstraction enabling the access to the directory services,
the JNDI provider uses the concept of&nbsp; a&nbsp; Directory Context (the
DirContext interface) to achieve the same functionality. A DirContext as
an equivalent of a directory entry in the ldapjdk.
<p>The following sections are available in this document:
<p><a href="#Using">Using Netscape Ldap Service Provider</a>
<br><a href="#Env Props">Environment Properties</a>
<br><a href="#Controls">Working With Controls</a>
<br><a href="#Not Impl">What's Not Implemented</a>
<br>&nbsp;
<h3>
<a NAME="Using"></a>Using Netscape LDAP Service Provider</h3>
The current implementation&nbsp; is based on the JNDI 1.2 FCS. In addition
to the DirContext interface implementation, the Netscape LDAP provider
implements the new JNDI event service (<i>javax.naming.event</i> package)
and support for controls (<i>javax.naming.ldap</i> package) which were
introduced with the JNDI 1.2.
<p>To use the service provider, you'll need to:
<p>(1) Add the provider and the jars it depends on in the classpath. For
example, on Windows NT the classpath should be set as follows:
<p><tt>set classpath=%classpath%;ldapsp.jar;ldapjdk.jar;jndi.jar;</tt>
<p>Assuming that all the jars are available in the current directory. The
listed jar files are:

<td WIDTH="100">ldapsp.jar&nbsp;</td>

<td WIDTH="400">Netscape LDAP Service Provider for JNDI</td>
</tr>

<tr>
<td>ldapjdk.jar</td>

<td>Netscape Directory SDK for Java 4.0</td>
</tr>

<tr>
<td>jndi.jar</td>

<td>JNDI 1.2</td>
</tr>
</table>

<p>(2) Specify the Netscape LDAP provider as the provider in the context
environment created for the initial context;
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <tt>Hashtable env = new Hashtable();</tt>
<br><tt>&nbsp;&nbsp; env.put(Context.INITIAL_CONTEXT_FACTORY,</tt>
<br><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; "com.netscape.jndi.ldap.LdapContextFactory");</tt>
<br><tt>&nbsp;&nbsp;&nbsp; env.put(...</tt>
<br><tt>&nbsp;&nbsp;&nbsp; ...</tt>
<br><tt>&nbsp;&nbsp;&nbsp; DirContext ctx = new InitialDirContext(env);</tt>
<p>(3) For storing of&nbsp; Java objects in a LDAP Directory, the JNDI
java object schema must be added to the directory. To enable the JNDI schema
copy the file <i>java-object-schema.conf</i>&nbsp; to your <i>&lt;server-root>/slapd-&lt;id>/config</i>
directory, and include the file into your&nbsp; <i>&lt;server-root>/slapd-&lt;id>/config/ns-schema.conf</i>
schema configuration file. If you are using Netscape Directory Server 4.1,
you just need to replace the existing&nbsp; <i>java-object-schema.conf</i>&nbsp;
file.
<p>For examples of using JNDI please go to the official JNDI site.
<h3>
<a NAME="Env Props"></a>Environment Properties</h3>
The environment properties can be passed directly to the initial context
as a hash table, or specified as system properties. For compatibility reasons,
for those environment properties that are relevant to LDAP protocol but
are not defined in the JNDI, the Netscape LDAP provider is using the same
property names as the SUN LDAP service provided, if a property with the
same semantics is defined by the SUN provider.
<p>Note: If a new property is added to the context environment, or an existing
property is changed after the initial context is created, the change will
be immediately visible unless the changed property pertains to the connection.
For changes related to connection, in order to take effect you'll need
to invoke <i>LdapContext.reconnect().</i>
<p>The following table contains JNDI environment properties are relevant
for the Netscape LDAP service provider. Properties not found in this table
are silently ignored.

the Netscape LDAP provider "<b>com.netscape.jndi.ldap.LdapContextFactory</b>"
should be specified.

<td>
<br>Specifies LDAP server information. For example:
<p><tt>env.put(Context.PROVIDER_URL, "ldap://dilly.mcom.com:389");</tt>
<p>If it has not been set then the provider will attempt to access an LDAP
server at port 389 on the local host.</td>
</tr>

<tr>
<td>java.naming.ldap.version</td>

<td>
<br>Specifies the protocol version for the provider. Two values are
<br>possible:
<ul>
<li>

<li>
3 - selects LDAP Version 3 (LDAPv3)</li>
</ul>
&nbsp;For example,&nbsp; <tt>env.put("java.naming.ldap.version", "3");</tt>
<p>If this environment property has not been set then the provider will
<br>attempt to use LDAPv3.</td>

(anonymous)</li>

<li>
&nbsp;&nbsp; <b>simple</b>&nbsp;&nbsp; - use weak authentication (clear

</ul>
If this environment property has not been set but the&nbsp;&nbsp;&nbsp;&nbsp;

the provider will use anonymous bind.</td>

<p>When this environment property has been set and the
<br>&nbsp;<i>java.naming.ldap.factory.socket</i> property has not been
set, then the ldapjdk default socket factory&nbsp; <i>netscape.net.SSLSocket</i>

results are returned in batches of one.</td>
</tr>

<tr>
<td>java.naming.ldap.maxresults</td>

<td>
<br>The default&nbsp; maximum number of search results to be returned for

default follows referrals.</td>

values as either Strings or byte arrays. All attributes are returned as
Strings unless recognized as having binary syntax. The values of attributes
that have binary syntax are returned as byte arrays instead of Strings.&nbsp;

<h3>
<a NAME="Controls"></a>Working with Controls</h3>
JNDI 1.2 adds support for Controls which are fully implemented with the
Netscape LDAP provider. However, JNDI 1.2 does not define interfaces for
any of the standard controls, like for example the sort control. Instead,
the task of defining particular controls and their interfaces is left to
service providers. Therefore, if using controls, you will also need to
import the&nbsp; <i>com.netscape.jndi.ldap.controls</i> package in your
souce in addition to the JNDI packages.
<p>Being implemented on the top of ldapjdk, the Netscape LDAP provider
simply exposes all of the ldapjdk controls as JNDI controls. Thus, the
control APIs are exactly the same as in ldapjdk. The only difference is
that for the LDAP provider controls class names start with&nbsp; "Ldap"
while in ldapjdk the class names start with "LDAP". For instance, the ldapjdk
control LDAPSortControl is LdapSortControl in the Netscape LDAP provider.
<p>Here is an example of how to use the LdapSortControl. Notice that you'll
need to obtain a LdapContext object as an initial context, because controls
are not part of the directory context (DirContext). That means that instead
of calling <i>getInitialDirContext()</i> you 'll need to call <i>getInitialLdapContext()</i>.

<h3>
<a NAME="Not Impl"></a>What's Not Implemented</h3>
Currently, the following JNDI features are not implemented by the Netscape
JNDI provider:
<ul>
<li>
Support for federated names</li>

<li>
Support for the code base attribute for objects stored in LDAP directory.
Therefore, the class name specified with the <i>javaClassName</i> attribute
must be available in the local <i>CLASSPATH</i>.</li>

<li>
<i>search()</i>&nbsp; method for schema directory contexts. Instead, <i>Context.lookup()</i>
should be used..</li>
