Enumerates the names bound in the named context, along with the class names of objects bound to them.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    String url = "ldap://localhost/o=JNDITutorial";
    Hashtable<String, String> env = new Hashtable<String, String>();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, url);
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, "userDN");
    env.put(Context.SECURITY_CREDENTIALS, "secret");

    Control[] connectCtls = new Control[] { null };
    LdapContext ctx = new InitialLdapContext(env, null);

    Control[] ctxCtls = new Control[] { new SortControl(new String[] { "cn" }, Control.CRITICAL) };

    ctx.setRequestControls(ctxCtls);/*  w  ww.  ja  va 2 s . c  o  m*/

    NamingEnumeration answer = ctx.list("");

    while (answer.hasMore()) {
        NameClassPair item = (NameClassPair) answer.next();
    }
}
