when I use JNDI to add an attribute to openldap schema, I get a problem,
following is my program.

import javax.naming.directory.*;
import javax.naming.*;
import java.util.Hashtable;
public class add {
   public add() {
  }


  public static void main(String[] args) {
 String password = "cm"; 
   String basedn = "dc=cm,dc=com"; 
   DirContext ctx = null;
   Hashtable env = new Hashtable();
  env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
/
  env.put(Context.PROVIDER_URL, "ldap://localhost:389/"+basedn ); 
  env.put(Context.SECURITY_AUTHENTICATION, "simple"); 
  env.put(Context.SECURITY_PRINCIPAL, "cn=root,"+basedn ); 
  env.put(Context.SECURITY_CREDENTIALS, password);
  try {
    ctx = new InitialDirContext(env); 
    System.out.println("connect ok");
  }
  catch (Exception e) {
    System.out.println(e.toString());
  }

  try{
   DirContext schemaCtx = ctx.getSchema("");
   BasicAttributes attrs = new BasicAttributes(true);
   attrs.put("NAME", "test");
   attrs.put("NUMERICOID", "1.3.6.1.4.1.7914.1.2.1.16");
   attrs.put("SYNTAX", "1.3.6.1.4.1.1466.115.121.1.15");
   attrs.put("SINGLE-VALUE", "TRUE");
   schemaCtx.createSubcontext("AttributeDefinition/test", attrs);
  System.out.println("ok");
  }catch(Exception e){
  System.out.println("Exception in add():"+e);
 }
   }
}

I get the exception

Exception in add():javax.naming.OperationNotSupportedException: [LDAP: error
code 53 - modification of subschema subentry not supported]; remaining name ''

on trying to add an attribute.
 
All help is welcome,
Thank you
