<br><b><font size=+1>Attribute Viewers/Editor Questions</font></b>
<p><a NAME="What are attribute"></a><b>What are attribute viewers/editors?</b>
<p>The attribute viewer/editor is a means of displaying and/or editing
the contents of an attribute. Each attribute can contain a different value
that needs to be represented differently. For example, a 'jpegphoto' attribute
contains an image and an 'audio' attribute contains a sound and a 'name'
attribute contains some string. These three need to have different visual
representations. In the case of the image, the actual image might be displayed.
In the case of the sound, the sound might be played automatically or when
a play button is pressed. In the case of the name attribute a textbox with
the string might be displayed. The LDAP Browser/Editor allows users to
customize the viewers/editors for any attribute.
<p><a NAME="What attribute viewers/editors are distributed"></a><b>What
attribute viewers/editors are distributed with the Browser?</b>
<p>The following editors are currently distributed with the browser:
<ul>
<li>
<b>ImageEditor</b></li>

<ul>
<li>
allows the display of image files such as <b>JPEG</b> and <b>GIF</b>.</li>
</ul>

<li>
<b>CertificateEditor2</b></li>

<ul>
<li>
allows the display of <b>X.509</b> certificates.</li>
</ul>

<li>
<b>PasswordEditor</b></li>

<ul>
<li>
allows for generating and verifying <b>MD5</b>, <b>SHA</b>, and <b>Unix
Crypt</b> passwords.</li>
</ul>

<li>
<b>ControlViewer</b></li>

<ul>
<li>
allows for displaying friendly names of the LDAP controls contained in
the Root DSE.</li>
</ul>

<li>
<b>ExtBinaryEditor</b> (experimental in 2.8.1)</li>

<ul>
<li>
allows for executing external applications to view the contents of an attribute.</li>
</ul>

<li>
<b>ExtStringEditor</b> (experimental in 2.8.1)</li>

<ul>
<li>
allows for executing external applications to view the contents of an attribute.</li>
</ul>

<li>
<b>SoundEditor</b></li>

<ul>
<li>
allows the playing of sound files such as <b>AIFF</b>, <b>AU</b>, <b>WAV</b>,
<b>TYPE
0 MIDI</b>, <b>TYPE 1 MIDI</b> and <b>RMF</b>.</li>
</ul>
</ul>
<a NAME="How do I set default algorithm for the"></a><b>How do I set default
algorithm for the PasswordEditor?</b>
<p>By default the PasswordEditor will generate a new password using the
same algorithm as the algorithm used in the existing password. To force
the editor to always generate a specific type of password edit the <i>attributes.config</i>
file and add following arguments to the PasswordEditor line:
<pre>-algorithm [algorithmType] -force</pre>
where <i>algorithmType</i> is one of following: Crypt, MD5 or SHA. For
example, an entry for userpassword in my config file looks like following:
<pre>userpassword=binary,lbe.editor.PasswordEditor -algorithm crypt -force</pre>
Also, make sure that your server is configured to accept the algorithm
specified.
<p><a NAME="What is the ExtBinaryEditor and how can I use"></a><b>What
is the ExtBinaryEditor and how can I use it?</b>
<p>The <i>ExtBinaryEditor</i> is a generic editor for binary attributes
that allows for launching external applications to view the contents of
the attribute. You can configure the <i>ExtBinaryEditor</i> to launch an
external application to view the certificate by adding the following arguments
to the <i>ExtBinaryEditor</i> line in the <i>attributes.config</i> file:
<pre>-ext -extcmd "command {0}"</pre>
where <i>command </i>is an application to execute and <i>{0} </i>is an
argument to the application. The argument is a filename that contains the
data of the selected attribute.
<br>Example:
<pre>certificateRevocationList=binary,lbe.editor.ExtBinaryEditor -ext -extcmd "rundll32.exe cryptext.dll,CryptExtOpenCRL {0}"</pre>
The above example will allow to pass the data of the <i>certificateRevocationList</i>
attribute to Windows default CRL viewer. (This assumes all the necessary
software is installed)
<p><a NAME="What is the ExtStringViewer and how can I use"></a><b>What
is the ExtStringViewer and how can I use it?</b>
<p>The <i>ExtStringViewer</i> is a generic viewer for the regular attributes
that allows for passing the attribute value to an external application.
For example, it could be used to pass an email address to mail application.
It is used and configured the same as the <i>ExtBinaryEditor</i> where
the only difference is that the <i>{0}</i> argument is the actual value
of the selected attribute. Please see the <a href="#What is the ExtBinaryEditor and how can I use">question</a>
about the <i>ExtBinaryEditor</i> for details.
<br>The following example will pass the email address stored in the mail
attribute to Outlook Express on Windows. (This assumes all the necessary
software is installed)
<pre>mail=string,lbe.editor.ExtStringViewer -ext -extcmd "C:\\Program Files\\Outlook Express\\msimn.exe /mailurl:mailto:{0}"</pre>
<a NAME="How can I configure the CertificateEditor2 to"></a><b>How can
I configure the CertificateEditor2 to launch an external application to
view the certificate?</b>
<p>You can configure the <i>CertificateEditor2</i> to launch an external
application to view the certificate in the same way as you configure the<i>
ExtBinaryEditor</i>. Please see the <a href="#What is the ExtBinaryEditor and how can I use">question</a>
about the <i>ExtBinaryEditor</i> for details.
<br>The following example will pass the certificate to Windows certificate
wizard: (This assumes all the necessary software is installed)
<pre>usercertificate=binary,lbe.editor.CertificateEditor2 -ext -extcmd "rundll32.exe cryptext.dll,CryptExtOpenCER {0}"</pre>
<a NAME="How do I write a custom attribute"></a><b>How do I write a custom
attribute viewer/editor?</b>
<p>Two things:
<blockquote>1. Extend some JComponent (from SwingSet) e.g. JPanel, JTextField,
JTable.
<br>2. Implement the AttributeEditor interface.
<p>or
<p>1. Extend BinaryEditor (for binary values) or DefaultEditor (for string
values) or any other built-in editor.
<br>2. Override needed methods.</blockquote>

<br><b><font size=+1>SSL Questions</font></b>
<p><a NAME="How do I enable the SSL support in the"></a><b>How do I enable
the SSL support in the Browser?</b>
<p>The Browser is closely integrated with the JSSE library from Sun. It
is a free pure Java SSL library.
<br>To enable the SSL support in the Browser do the following:
<ol>
<li>
Download JSSE from: <a href="http://java.sun.com/products/jsse/">http://java.sun.com/products/jsse.</a></li>

<li>
Install the JSSE package:</li>

<ul>
<li>
either by following the <a href="http://java.sun.com/products/jsse/install.html">general
installation instructions</a>, or by</li>

<li>
copying the <i>jnet.jar, jsse.jar, jcert.jar</i> files from the <i>lib/</i>
directory of the JSSE package to the<i> lib/ </i>directory of the Browser.</li>
</ul>
</ol>
And that's all. To connect using SSL just make sure to select the SSL box
in the connect window and specify the right port number.
<p><a NAME="Why does initial SSL connection take a while to"></a><b>Why
does initial SSL connection take a while to establish?</b>
<p>The very first time a secure connection is established Java must create
a secure seed required for the SSL connection. This is a very computationally
expensive process and may take up to a few seconds on certain platforms.
However, the seed only needs to be computed once per session.
<p><a NAME="How do I turn on debugging for the SSL"></a><b>How do I turn
on debugging for the SSL connection?</b>
<p>To enable debug mode for secure connections use
<pre>-Djavax.net.debug=all</pre>
option on the command line to the Java interpreter. For example:
<pre>java -Djavax.net.debug=all -classpath .....&nbsp; lbe.ui.BrowserApp</pre>
For details on how to modify the 'lbe' scripts to enable this property
see the&nbsp; <a href="#How do I modify the 'lbe' scripts to add the">question</a>
about this.
<p><a NAME="How do I specify client certificates for the SSL"></a><b>How
do I specify client certificates for the SSL connection?</b>
<p>To specify the client certificates you must create a Java keystore (using
keytool) with your certificates and then add the path to the keystore and
the password of the keystore to the configuration file.
<br>For example:
<pre>&nbsp;&nbsp; keystore&nbsp;&nbsp; = .keystore
&nbsp;&nbsp; passphrase = abcdef</pre>
Please note, however, that these settings should be only set in one configuration
file. Also, these settings will only work with the default secure socket
factory that is built-in with the browser. If different socket factory
is used, it might have another way of specifying these options.
<p><a NAME="Why does SSL connection sometimes hang the"></a><b>Why does
an SSL connection sometimes hang the browser</b>?
<p>Most likely this occurs when the ldap port number specified in the connection
windows was not a SSL port. If non-secure socket is used to connect to
a server's SSL socket, then the application using the non-secure socket
will hang. This is a characteristic of the SSL protocol.
