<br><a NAME="new41"></a><b><font face="Arial,Helvetica"><font size=+1>What's
New in Version 4.1</font></font></b>
<p>The Directory SDK 4.1 for Java is a bug fix relase. Please check the
list of <a href="#fixed40">Bugs Fixed Since Version 4.0</a>. The following
new features have been added in this release:
<ul>
<li>
A new class, <tt>netscape.ldap.factory.JSSESocketFactory</tt>. It implements
the <tt>LDAPSocketFactory</tt> interface using the Java Secure Socket Extension
(JSSE)&nbsp; intefaces as the SSL provider. A JSSE implementation is not
packaged with the Directory SDK classes; you will need to have one in your
CLASSPATH to be able to use <tt>JSSESocketFactory</tt>.&nbsp; A reference
implementation of JSSE interfaces is available at <a href="http://java.sun.com/products/jsse/">http://java.sun.com/products/jsse/</a>.</li>

<li>
A new interface,&nbsp; <tt>netscape.ldap.LDAPTraceWriter,</tt> enables
logging of LDAP trace messages in environments where an <tt>OutputStream</tt>
cannot be used. The interface is meant primarily for integrating LDAP tracing
with the servlet log facility.</li>

<li>
A new method <tt>setConnectTimeout() </tt>has been added to <tt>LDAPConnection.
</tt>This
method allows you to limit&nbsp; the amount of time that application code
waits for <tt>LDAPConnection.connnect() </tt>to establish a connection.
By setting the connect timeout, an application can avoid blocking for a
long period of time when a Directory Server host is down or unreachable.</li>

<li>
All base classes in the <tt>netscape.ldap</tt> and <tt>netscape.ldap.util</tt>
package are now serializable.</li>
</ul>

<p><a NAME="new"></a><b><font face="Arial,Helvetica"><font size=+1>What's
New in Version 4.0</font></font></b>
<p>The Directory SDK 4.0 for Java provides programmers with the tools to
develop directory-enabled software.&nbsp; This release includes:
<ul>
<li>
Application Program Interface (API) updates to match the newest LDAP (Lightweight
Directory Access Protocol) internet drafts</li>

<li>
an asynchronous interface to LDAP</li>

<li>
a new SASL (Simple Authentication and Security Layer) API</li>

<li>
the Netscape LDAP Service Provider for LDAP.</li>
</ul>
Additional improvements and changes to the Directory SDK are listed under
<a href="#fixed305">Bugs
Fixed Since Version 3.05</a>.
<p><b><font face="Arial,Helvetica">API updates</font></b>
<p>The Directory SDK 4.0 for Java supports these changes to the LDAP API:
<ul>
<li>
Sophisticated client-side management of referral authentication using the
<tt>LDAPBind</tt>
interface.</li>

<li>
Dynamic registration and instantiation of server response controls using
the <tt>register</tt> and <tt>newInstance</tt> methods of <tt>LDAPControl</tt>.</li>

<li>
The separation of the constraint class into <tt>LDAPConstraints</tt> and
its subclass <tt>LDAPSearchConstraints</tt>. <tt>LDAPConstraints</tt> contains
only those methods implemented in the interface that apply to <i>all </i>operations.
<tt>LDAPSearchConstraints</tt>
is unchanged. All <tt>LDAPConnection</tt> methods that used to take <tt>LDAPSearchConstraints</tt>
as an argument (except for read and search methods) now pass <tt>LDAPConstraints</tt>
instead.</li>

<li>
When using <tt>LDAPConnection</tt> for searching, retrieval of server response
controls is now handled by <tt>LDAPSearchResults</tt>. Although the SDK
is backward compatible, you should call <tt>LDAPSearchResults.getResponseControls()</tt>
instead of <tt>LDAPConnection.getResponseControls()</tt>when writing new
code.</li>

<li>
<tt>LDAPConnection.getServerControls()</tt> now automatically parses controls.
As a result, calling <tt>parseResponse()</tt> is no longer necessary.</li>

<li>
Support for transparent failover connection policies. The available policies
are: (1) serial, (2) parallel with no delay, and (3) parallel with delay.
For more information, see <tt>LDAPConnection.setConnSetupDelay()</tt> in
the javadocs.</li>

<li>
<tt>LDAPConnection</tt> has a new method called <tt>reconnect()</tt>. This
method first disconnects and then connects and binds again using the same
parameters and mechanisms as the original connection..</li>

<li>
Support for connection pools. For more information see <tt>netscape.ldap.util.ConnectionPool</tt>
in the javadocs.</li>

<li>
The addition of <tt>LDAPInterruptedException</tt>, which is thrown if an
LDAP operation is interrupted.</li>

<li>
The addition of <tt>LDAPProxiedAuthControl</tt>, which can execute operations,
using different credentials, without rebinding.</li>

<li>
<tt>LDAPConnection</tt> now runs as a daemon thread. You no longer need
to call <tt>System.exit</tt> when terminating your program.</li>
</ul>
<b><font face="Arial,Helvetica">Asynchronous API</font></b>
<p>The Directory SDK 4.0 for Java provides an interface called
<tt>LDAPAsynchronousConnection</tt>.
This interface contains methods for performing LDAP operations asynchronously.
Instead of blocking while waiting for a response, methods in <tt>LDAPAsynchronousConnection</tt>
return control to an application before they complete. For more information
on the asynchronous interface, see "<a href="http://developer.netscape.com/docs/manuals/dirsdk/jsdk40/asynch.htm">Using
the Asynchronous Interface</a>" in the <i><a href="http://developer.netscape.com/docs/manuals/dirsdk/jsdk40/contents.htm">Netscape
Directory SDK 4.0 for Java Programmer's Guide</a></i>.
<p><b><font face="Arial,Helvetica">SASL API</font></b>
<p>SASL allows clients and servers to communicate securely. The API accomplishes
this by finding a common authentication scheme and facilitating a series
of challenge and response interchanges between the client and server. If
these interchanges complete successfully, the client is authenticated.
For more information on SASL see "<a href="http://developer.netscape.com/docs/manuals/dirsdk/jsdk40/sasl.htm">Using
SASL Authentication</a>" in the <i><a href="http://developer.netscape.com/docs/manuals/dirsdk/jsdk40/contents.htm">Netscape
Directory SDK 4.0 for Java Programmer's Guide</a></i>.
<p><b><font face="Arial,Helvetica">JNDI Service Provider for LDAP</font></b>
<p>JNDI is a Java API that provides a common way for programmers to access
a variety of naming and directory services. This is accomplished via a
layer of software called a Service Provider. The Directory SDK includes
a Service Provider for LDAP.
<p>The following JNDI features are not implemented in this release of the
Netscape LDAP Service Provider:
<ul>
<li>
Support for federated names</li>

<li>
Support for the "code base" attribute for objects stored in an LDAP directory.
The class name specified by the <tt>javaClassName</tt> attribute must exist
in the local <tt>CLASSPATH</tt></li>

<li>
The <tt>search()</tt> method for schema directory contexts. To perform
searches in a schema directory context use a <tt>Context.lookup()</tt>
request instead of <tt>DirContext.search()</tt>.</li>
</ul>
For more information see "<a href="http://developer.netscape.com/docs/manuals/dirsdk/jsdk40/JNDIchap.htm">Using
the JNDI Service Provider</a>" in the <i><a href="http://developer.netscape.com/docs/manuals/dirsdk/jsdk40/contents.htm">Netscape
Directory SDK 4.0 for Java Programmer's Guide</a></i>.
