java - 如何将Java连接到Active Directory

我使用的是WebLogic,EJB3.0。爪哇1.6
我需要通过Java代码访问ActiveDirectory。
我阅读了几种方法(kerberos、ldap)
有人能给我一个舒服的建议吗?我在哪里可以有一些完整的代码示例,
谢谢,
雷。


最佳答案:

下面是一个简单的代码,它使用W2K3上的JNDI进行身份验证和LDAP搜索:

class TestAD
{
  static DirContext ldapContext;
  public static void main (String[] args) throws NamingException
  {
    try
    {
      System.out.println("Début du test Active Directory");

      Hashtable<String, String> ldapEnv = new Hashtable<String, String>(11);
      ldapEnv.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
      //ldapEnv.put(Context.PROVIDER_URL,  "ldap://societe.fr:389");
      ldapEnv.put(Context.PROVIDER_URL,  "ldap://dom.fr:389");
      ldapEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
      //ldapEnv.put(Context.SECURITY_PRINCIPAL, "cn=administrateur,cn=users,dc=societe,dc=fr");
      ldapEnv.put(Context.SECURITY_PRINCIPAL, "cn=jean paul blanc,ou=MonOu,dc=dom,dc=fr");
      ldapEnv.put(Context.SECURITY_CREDENTIALS, "pwd");
      //ldapEnv.put(Context.SECURITY_PROTOCOL, "ssl");
      //ldapEnv.put(Context.SECURITY_PROTOCOL, "simple");
      ldapContext = new InitialDirContext(ldapEnv);

      // Create the search controls         
      SearchControls searchCtls = new SearchControls();

      //Specify the attributes to return
      String returnedAtts[]={"sn","givenName", "samAccountName"};
      searchCtls.setReturningAttributes(returnedAtts);

      //Specify the search scope
      searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);

      //specify the LDAP search filter
      String searchFilter = "(&(objectClass=user))";

      //Specify the Base for the search
      String searchBase = "dc=dom,dc=fr";
      //initialize counter to total the results
      int totalResults = 0;

      // Search for objects using the filter
      NamingEnumeration<SearchResult> answer = ldapContext.search(searchBase, searchFilter, searchCtls);

      //Loop through the search results
      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("Total results: " + totalResults);
      ldapContext.close();
    }
    catch (Exception e)
    {
      System.out.println(" Search error: " + e);
      e.printStackTrace();
      System.exit(-1);
    }
  }
}
