Hi

I am looking for a quick ldap example on how to store something in a directory tree in LDAP.

Lets say I have the following

User = directory
     - name  = value
     - password = value

Can anyone give me quick example on how to do this in LDAP using JNDI?

Thanks
Marius

Hi,
Try this code ,
Make sure u have ldap provider in yur classpath.
You have to download it from sun site.

Initial context would depend upon yur Ldap server.
You will have to provide these values while building an initial context like Server adds, Base DN, authentication (if the server does).




import javax.naming.*;
import javax.naming.directory.*;

import java.util.Hashtable;


class Modattrs {
  public static void main(String[] args) {
    Hashtable env = new Hashtable(11);
    env.put(Context.INITIAL_CONTEXT_FACTORY,          "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://severname");

    try {
     // Create the initial context
     DirContext ctx = new InitialDirContext(env);
     String name = "cn=Ted Geisel, ou=People";

     // Save original attributes
     Attributes orig = ctx.getAttributes(name);

     // Specify the changes to make
     ModificationItem[] mods =new ModificationItem[3];

     mods[0] = new ModificationItem(DirContext.ADD_ATTRIBUTE,new BasicAttribute("dir", "\user\home"));

     mods[1] = new ModificationItem(DirContext.ADD_ATTRIBUTE,
          new BasicAttribute("cn", "chauhanvinit"));
         
        mods[2] = new ModificationItem(DirContext.ADD_ATTRIBUTE,new BasicAttribute("passwd", "empty"));
         ctx.modifyAttributes(name, mods);
        // Check attributes
     System.out.println("**** new attributes *****");
     GetattrsAll.printAttrs(ctx.getAttributes(name));

     // Revert changes
     ctx.modifyAttributes(name, DirContext.REPLACE_ATTRIBUTE, orig);

     // Check that the attributes got restored
     System.out.println("**** reverted to original attributes *****");
     GetattrsAll.printAttrs(ctx.getAttributes(name));

     // Close the context when we're done
         ctx.close();
     } catch (Exception e) {
         e.printStackTrace();
     }
    }
}

yu will get detailed explaination at :-
