<div class="intro">
<p>This document covers the ldapjs errors API and assumes that you are familiar
with LDAP. If you're not, read the <a href="guide.html">guide</a> first.</p>
</div>
<p>All errors in the ldapjs framework extend from an abstract error type called
<code>LDAPError</code>. In addition to the properties listed below, all errors will have
a <code>stack</code> property correctly set.</p>
<p>In general, you'll be using the errors in ldapjs like:</p>
<pre><code class="language-js"><span class="hljs-keyword">const</span> ldap = <span class="hljs-built_in">require</span>(<span class="hljs-string">'ldapjs'</span>);
<span class="hljs-keyword">const</span> db = {};
server.<span class="hljs-title function_">add</span>(<span class="hljs-string">'o=example'</span>, <span class="hljs-function">(<span class="hljs-params">req, res, next</span>) =></span> {
<span class="hljs-keyword">const</span> parent = req.<span class="hljs-property">dn</span>.<span class="hljs-title function_">parent</span>();
<span class="hljs-keyword">if</span> (parent) {
<span class="hljs-keyword">if</span> (!db[parent.<span class="hljs-title function_">toString</span>()])
<span class="hljs-keyword">return</span> <span class="hljs-title function_">next</span>(<span class="hljs-keyword">new</span> ldap.<span class="hljs-title class_">NoSuchObjectError</span>(parent.<span class="hljs-title function_">toString</span>()));
}
<span class="hljs-keyword">if</span> (db[req.<span class="hljs-property">dn</span>.<span class="hljs-title function_">toString</span>()])
<span class="hljs-keyword">return</span> <span class="hljs-title function_">next</span>(<span class="hljs-keyword">new</span> ldap.<span class="hljs-title class_">EntryAlreadyExistsError</span>(req.<span class="hljs-property">dn</span>.<span class="hljs-title function_">toString</span>()));
...
});
</code></pre>
<p>I.e., if you just pass them into the <code>next()</code> handler, ldapjs will automatically
return the appropriate LDAP error message, and stop the handler chain.</p>
<p>All errors will have the following properties:</p>
<h2 id="code">code</h2>
<p>Returns the LDAP status code associated with this error.</p>
<h2 id="name">name</h2>
<p>The name of this error.</p>
<h2 id="message">message</h2>
<p>The message that will be returned to the client.</p>
