but I can't find how I add an entry into openLdap? how can I create a group with their idea?

Any one has some cule, please let me know, thanks

With LDAP Client.Net this is done with the AddNewEntry method. See http://www.ldapservices.com/Products/LdapClient.Net/API/LdapServices.Ldap.Client.AddNewEntry.html for details and a sample.

Hi,

I am new to Active Directory domain and i have been given a task to download a file stored on an Active Directory server using LDAP protocol. I have searched the net but couldnt find anything related to file tranfer via ldap. My questions are as follows:

1 - can files be stored on Active Directory along with users, printer and computers?
2 - if yes then how can we retrieve/download the file from the AD server? (prefferably using C#).
3 - does file transfer to/from Active Directory only involves LDAP or are there other factors to consider too?

please point me in the right direction, Any help will be greatly appreciated.

Thank & Regards,

I'm trying to create a new user record into OpenLDAP with object classes person and uidObject. The problem seems to be that with System.DirectoryServices.DirectoryEntry I've found only a way to add a new entry with one object class, but not a way to add multiple object classes.

This C# code

DirectoryEntry nRoot = new DirectoryEntry(path);
nRoot.AuthenticationType = AuthenticationTypes.None;
nRoot.Username = username;
nRoot.Password = pwd;

try
{
    DirectoryEntry newUser = nRoot.Children.Add("CN=" + "test", "person");
    newUser.Properties["cn"].Add("test");
    newUser.Properties["sn"].Add("test");
    newUser.Properties["objectClass"].Add("uidObject"); // this doesnt't make a difference
    newUser.Properties["uid"].Add("testlogin"); // this causes trouble
    newUser.CommitChanges();
}
catch (COMException ex)
{
    Console.WriteLine(ex.ErrorCode + "\t" + ex.Message);
}

newUser.Properties["objectClass"].Add("uidObject");
newUser.Properties["uid"].Add("testlogin");
newUser.CommitChanges();

Before you update any user information it is probably a good idea to find out if they actually exist in the Active Directory.

public bool UserExists(string username)
{
   DirectoryEntry de = GetDirectoryEntry();
   DirectorySearcher deSearch = new DirectorySearcher();

   deSearch.SearchRoot = de;
   deSearch.Filter = "(&(objectClass=user) (cn=" + username + "))";

   SearchResultCollection results = deSearch.FindAll();

   return results.Count > 0;
}

private String FindName(String userAccount)
{
   DirectoryEntry entry = GetDirectoryEntry();
   String account = userAccount.Replace(@"Domain\", "");

   try
   {
      DirectorySearcher search = new DirectorySearcher(entry);
      search.Filter = "(SAMAccountName=" + account + ")";
      search.PropertiesToLoad.Add("displayName");

      SearchResult result = search.FindOne();

      if (result != null)
      {
         return result.Properties["displayname"][0].ToString();
      }
      else
      {
         return "Unknown User";
      }
   }
   catch (Exception ex)
   {
      string debug = ex.Message;

      return "";
   }
}

The form I created has 2 textboxes (Username & Password) and a submit button. When the button is clicked all the events are fired and if everything checks out the user is updated in Active Directory.
