How to get entries in ldap?

[Paulo Aquino]

Hi! LDAP newbie here, so please be kind to me. Anyway, here is the directory structure

ou = People
ou = Services
ou = Extranet
-------ou = Groups
-------ou = People
--------------uid=pinolo
--------------uid=pizarro
--------------uid=racero
--------------uid=tirano

under the uid entry, these are some attributes:
uid
sn
givenName
mail
cn

What I need to do is to loop through all of the uid entries (pinolo, pizarro etc)....printing each uid entries then printing all attributes found under each entry. Can anyone help me with a code snippet?

[Paulo Aquino]

Sometime back, the foll. code used to work for me with Weblogic 8.1 Embedded LDAP database, but I guess it is likely to work with other LDAP servers also.

Which LDAP server are you using?

import java.util.Hashtable;
import java.util.Enumeration;
import javax.naming.*;
import javax.naming.directory.*;
 
public class LDAPTest {
    public static String INITCTX = "com.sun.jndi.ldap.LdapCtxFactory";
    public static String MY_HOST = "ldap://localhost:7001";    
    public static String MY_SEARCHBASE = "dc=workshop";
    public static String MY_FILTER = "uid=vodafone";    
 
    public static String MGR_DN = "cn=Admin";
    public static String MGR_PW = "vishwa";
 
public static void main(String[] args) {
    try {
        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY, INITCTX);
        env.put(Context.PROVIDER_URL, MY_HOST);
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, MGR_DN);
        env.put(Context.SECURITY_CREDENTIALS, MGR_PW);
 
        print("Attempting to create the Dir Context...");
        DirContext ctx = new InitialDirContext(env);
        print("Created the Dir Context...");
 
        SearchControls constraints = new SearchControls();
        constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
 
        //performs the actual search
        //We give it a searchbase, a filter and the contraints containing the scope of the search
        NamingEnumeration results = ctx.search(MY_SEARCHBASE, MY_FILTER, constraints);
 
        //now stop through the search results
        while(results != null && results.hasMore()) {
            SearchResult sr = (SearchResult)results.next();
            String dn = sr.getName();
            print("Distinguished name is " + dn);
            Attributes attrs = sr.getAttributes();
            for (NamingEnumeration ne = attrs.getAll();ne.hasMoreElements() ;)   {
                Attribute attr = (Attribute) ne.next();
                String attrID = attr.getID();
                System.out.println(attrID+" :");
                for(Enumeration vals = attr.getAll();vals.hasMoreElements() ;)   {
                    System.out.println("\t"+vals.nextElement());
                } //end of inner for
            }//end of outer for
 
            System.out.println("\n");
        }//end of while
   } catch(Exception ex) {
        ex.printStackTrace();
        System.exit(1);
    }
 
} // end of method
 
static void print(String msg) {
    System.out.println("LDAPTest: " + msg);
 }
 
}  // end of class
