Operações no AD com Java

Galera, nesse post vou compartilhar uma classe que possui operações de busca e atualização de conteúdo texto e de conteúdo do tipo imagem.

Segue abaixo a classe:

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.NamingEnumeration;
import javax.naming.NamingException;
import javax.naming.directory.Attributes;
import javax.naming.directory.BasicAttribute;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;
import javax.naming.directory.ModificationItem;
import javax.naming.directory.SearchControls;
import javax.naming.directory.SearchResult;
import org.apache.commons.io.IOUtils;

public class TestAD {

    private DirContext ldapContext;

    public TestAD() throws NamingException {

        ldapEnv.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        ldapEnv.put(Context.PROVIDER_URL,  "ldap://192.168.0.12:389");

        ldapContext = new InitialDirContext(ldapEnv);

    }

    public void buscarConteudos() throws NamingException {

        SearchControls searchCtls = new SearchControls();

        //Especifica os atributos que serao retornados
        String returnedAtts[]={"sn","givenName", "samAccountName", "thumbnailPhoto"};
        searchCtls.setReturningAttributes(returnedAtts);

        //Especifica o escopo de busca
        searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);

        //Especifica o filtro de busca - Busca conteúdo com samAccountName = bruno
        String searchFilter = "(&(samAccountName=bruno))";

        //Especifica a base de busca
        String searchBase = "CN=Users,DC=algumDC,DC=local";

        //Contador de resultados
        int totalResults = 0;

        // Realiza a busca
        NamingEnumeration<SearchResult> answer = ldapContext.search(searchBase, searchFilter, searchCtls);

        //Percorre os resultados retornados
        while (answer.hasMoreElements())
        {
          SearchResult sr = (SearchResult)answer.next();

          totalResults++;

          System.out.println(">>>" + sr.getName());
          Attributes attrs = sr.getAttributes();
          System.out.println(">>>>>>" + attrs.get("samAccountName"));
          System.out.println(">>>>>>" + attrs.get("thumbnailPhoto"));
        }

        System.out.println("Total results: " + totalResults);
    }

    public void atualizarConteudo() throws FileNotFoundException, IOException,
                                           NamingException {

        // Atualiza o campo 'givenName' pelo valor especificado
        mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE,

        byte[] imgByte = IOUtils.toByteArray(imgFIS);

        //Atualiza o campo thumbnailPhoto, precisa enviar um array de byte
        //Tamanho máximo de arquivo que o campo aceita é de 100kb
        mods[1] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE,
                     new BasicAttribute("thumbnailPhoto", imgByte));

        //Realiza o procedimento de atualização
        ldapContext.modifyAttributes("CN=algum CN,CN=Users,DC=algumDC,DC=local",  mods);
    }
