JNDI-Beispiel für LDAP Status Code 2 (protocolError)

Durchführung einer Bind-Operation gegen OpenLDAP 2.4, geforderte Protokollversion ist das veraltete LDAP v2. OpenLDAP quittiert das mit einem Statuscode 2 (protocolError), der von JNDI auf eine javax.naming.CommunicationException gemappt wird.

LDAP-Server: OpenLDAP 2.4, Host: magritte, Port:389
Java-Version: Java 7, JUnit 4

Java-Quelltext

@Test(expected=CommunicationException.class)
public void protocolError() throws NamingException {

   Hashtable<String, String> env = new Hashtable<>();
   env.put(Context.INITIAL_CONTEXT_FACTORY,
            "com.sun.jndi.ldap.LdapCtxFactory");
   env.put(Context.PROVIDER_URL,
            "ldap://magritte:389");
   env.put("java.naming.ldap.version", "2");

   InitialDirContext ctx = new InitialDirContext(env);
   ctx.list("");
}
