Javax.naming.InvalidNameException

Question

Hi I have the following problem.
I want to get an object from AD. But every time I get the follwing result after running:
Lookup failed: javax.naming.NameNotFoundException: [LDAP: error code 32 - 0000208D: NameErr: DSID-031001CD, problem 2001 (NO_OBJECT), data 0, best match of:
     'DC=fzi,DC=de'
I ran successfull *ctx.list*() and *ctx.search()* with SubtreeScope. But when I want to lookup(), It doesn't run successfully.
Here is the sample code (but notice that I deleted my pw in Context.SECURITY_CREDENTIALS
import java.io.IOException;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.naming.ldap.LdapContext;
public class GetUser {
    public static void main(String[] args) throws IOException {
Hashtable<String, Object> env = new Hashtable<String, Object>();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
String ldapURL = "ldap://ldap.fzi.de:3268/DC=fzi,DC=de";
//connect to my domain controller
env.put(Context.PROVIDER_URL,ldapURL);
//set security credentials, note using simple cleartext authentication
env.put(Context.SECURITY_AUTHENTICATION,"simple");
env.put(Context.SECURITY_PRINCIPAL,"[email protected]");
env.put(Context.SECURITY_CREDENTIALS,"....");
try {
//Create the initial directory context
Context ctx = new InitialContext(env);
LdapContext user = (LdapContext)ctx.lookup("CN=Ugur Kocak,OU=Users,OU=PROST");
System.out.println(user);
ctx.close();
catch (NamingException e) {
System.out.println("Lookup failed: " + e);
It would be very nice if someone can help me
Best regards
Ugur

Hi,
I am getting the same error. But I am not running ctx.list or ctx.search method. I am just trying to change the User password in AD.
           DirContext ldapContext;
        String baseName = "CN=APOPSDC, DC=ispl, DC=com";
        String based = " ";
        String serverIP = "apopsdc";
        String modelUsername = "template";
        System.out.println("works");
          Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
            String keystore = "C:\\Program Files\\Java\\jdk1.6.0_26\\jre\\lib\\security\\cacerts";
            System.setProperty("javax.net.ssl.trustStore",keystore);
              // the keystore that holds trusted root certificates
        try {
            Hashtable env = new Hashtable(11);
            env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
            String ldapURL = "ldap://***********:636";
            env.put(Context.PROVIDER_URL, "ldap://********.636");
            env.put(Context.SECURITY_AUTHENTICATION, "Simple");
            //it can be <domain\\userid> something that you use for windows login
            //it can also be
            String userName = "ispl\\navin.kumar";
            env.put(Context.SECURITY_PRINCIPAL, "************");
            env.put(Context.SECURITY_CREDENTIALS, "********");
            env.put(Context.SECURITY_PROTOCOL, "ssl");
            //in following property we specify ldap protocol and connection url.
            //generally the port is 389
            ldapContext = new InitialDirContext(env);
            DirContext ctx = (DirContext)ldapContext;
            System.out.println("Context Sucessfully Initialized");
            ModificationItem[] mods = new ModificationItem[1];
            mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, new BasicAttribute("userpassword" ,"********" ));
            System.out.println("step 3");
            //ldapContext.modifyAttributes("cn=" + username + baseName, mods);
            System.out.println("dn = " + "cn=" + ldapURL + userName);
            ctx.modifyAttributes(based, mods);
            System.out.println("step 4");
            System.out.println("success base");
            ctx.close(); 
        } catch (Exception e) {
            System.out.println(" bind error: " + e);
            e.printStackTrace();
            System.exit(-1);
        }When I run this, I am getting the following error :
"dn = cn=ldap://apopsdc.ispl.com:636ispl\*******
bind error: javax.naming.NameNotFoundException: [LDAP: error code 32 - 0000208D: NameErr: DSID-031001A8, problem 2001 (NO_OBJECT), data 0, best match of:
{code}
What is the problem here?
