This is where i have reached so far:

    Hashtable<String, Object> env = new Hashtable<String, Object>();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://localhost:389/dc=server,dc=lan");
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, "cn=admin,dc=server,dc=world");
    env.put(Context.SECURITY_CREDENTIALS, "william");

    DirContext context = null;

    NamingEnumeration namingEnumeration = null;
    try {
        context = new InitialDirContext(env);
        System.out.println("Connection Successful.");

        SearchControls controls = new SearchControls();
        controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
        namingEnumeration = context.search("dc=server,dc=lan,cn=admin", "objectClass=posixGroup", controls);
        while (namingEnumeration.hasMore()) {
            SearchResult searchResult = (SearchResult) namingEnumeration.next();
            Attributes attributes = searchResult.getAttributes();
            Attribute attr = attributes.get("cn");
            String cn = (String) attr.get();
            System.out.println(" Person Common Name = " + cn);
        }

    } catch (Exception e) {
        System.out.println(e.getMessage());
        e.printStackTrace();

    } catch (Throwable e) {
        e.printStackTrace();
    } finally {
        if (namingEnumeration != null) {
            try {
                namingEnumeration.close();
            } catch (Exception e) {
            }
        }
        if (context != null) {
            try {
                context.close();
            } catch (Exception e) {
            }
        }


}

The error message means that the object "dc=server,dc=lan,cn=admin" cannot be found.

Your search base should probably be "cn=admin,dc=server,dc=lan"
