<h3>e492. Authenticating to the Directory</h3>
This example uses the JNDI/LDAP service provider to
create an authenticated session to an LDAP server on the local machine,
by using <font color="#0066ff"><i>simple</i></font> authentication.
<pre> String url = <font color="#0066ff"><i>"ldap://localhost/o=JNDITutorial"</i></font>;
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, <font color="#0066ff"><i>"com.sun.jndi.ldap.LdapCtxFactory"</i></font>);
env.put(Context.PROVIDER_URL, url);
env.put(Context.SECURITY_AUTHENTICATION, <font color="#0066ff"><i>"simple"</i></font>);
env.put(Context.SECURITY_PRINCIPAL, <font color="#0066ff"><i>"userDN"</i></font>);
env.put(Context.SECURITY_CREDENTIALS, <font color="#0066ff"><i>"secret"</i></font>);
try {
DirContext ctx = new InitialDirContext(env);
} catch (NamingException e) {
}
