Setting LDAP Context Request Controls</h3>
This example uses the JNDI/LDAP service provider to connect
to an LDAP server on the local machine. It sets the context's
request controls to be a server-side Sort control and then
performs a <code>list()</code>. The results of <code>list()</code> will be sorted.
<pre>
try {
LdapContext ctx = new InitialLdapContext(env, null);
// Create critical Sort that sorts based on CN
Control[] ctxCtls = new Control[]{
<font color="#0066ff"><i>new SortControl(new String[]{"cn"}, Control.CRITICAL)</i></font>
};
// Sets context request controls; effect until unset
ctx.setRequestControls(ctxCtls);
// Perform list() with controls in effect
NamingEnumeration answer = ctx.list("");
// Enumerate answers
while (answer.hasMore()) {
NameClassPair item = (NameClassPair)answer.next();
}
} catch (NamingException e) {
}
</pre>
