i have googled it and read all stuff about active directory.. it is really easy to say "look for it on google". i still have no answer. if you have any information about Acvite Directory and Java, could you help me please ?
this is what i got on google, i have changed it and tried a lot of times; but it isn't work... i wrote the server id. it doesn'T connect. do u know why ????

Code:

---

    public DirContext ActiveDirectory(String serverName, String username, String password) {
        DirContext dirContext = null;                      //  returned to the calling program
        Hashtable environment = new Hashtable();          //  holds parameters that will be passed to the AD server

        //  Set up the Active Directory environment.               
        environment.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
        environment.put(Context.PROVIDER_URL, "ldap://" + serverName);
        //environment.put(Context.SECURITY_AUTHENTICATION, "simple");
        //environment.put(Context.SECURITY_PRINCIPAL, username);
        //environment.put(Context.SECURITY_CREDENTIALS, password);
        environment.put(Context.REFERRAL, "follow");

        try {
              dirContext = new InitialDirContext(environment);        //  Retrieve a "connection" to the Active Directory server.
        } catch (Exception ex) {
              System.err.println(ex);
        }

        return dirContext;
    }
   
    public String getDnBySamAccountName(String networkUsername, String context, DirContext dctx) throws Exception {
    String subEntry;

    try {
          //  A SearchControls object holds information about the scope of a search.
          SearchControls controls = new SearchControls();
          controls.setSearchScope(SearchControls.SUBTREE_SCOPE);

          //  searchString describes what we're looking for, a person, not a computer, with the specified name.
          String searchString = "(&(objectClass=person)(!(objectClass=computer))(sAMAccountName=" + networkUsername +"))";

          //  NamingEnumeration is an interface for lists returned by methods in the javax.naming and javax.naming.directory packages.
          //  In our case, it's going to hold the results of our search.
          NamingEnumeration enumer = dctx.search(context, searchString, controls);

          if (enumer!=null) {
              subEntry = ((SearchResult) enumer.next()).getName();
              return subEntry;
          }
    }
    catch (NullPointerException e) {
         
    }
    catch (Exception e) {
          System.err.println(e);
    }
    return null;
}

this is the error message which i get:

javax.naming.CommunicationException: ***.***.*.**:*** [Root exception is java.net.ConnectException: Connection timed out: connect]

Presumably because you aren't giving it any login details?

password and username ???

I thought AD servers required you to logon.

Normally, yes.

@OP, using the url and credentials given above can you access the server from outside your program.
