  List of users from Active Directory?

  Oct 14, 2008 07:40 PM|LINK

  Can someone please tell me how to get a listing of users and their user account numbers (in string type, or easily convertible to string type) from active directory? Sample code would be nice. I've googled this already with no success; lot's of code that claims to do it, none that I have been able to get to work.

  Thanks!

   With this code, you can search an active directory create a list of usernames, if you need more propertys,build a struct, and fill a list with this structs.

   

  DirectoryEntry domain1;
  DirectorySearcher searcher1;
  List<string> lista1 = new List<string>();
  
  
  dominio = new DirectoryEntry("LDAP://test.com/DC=dept1,DC=com", "domainadmin", "12345", AuthenticationTypes.ReadonlyServer);
  
  
  searcher1= new DirectorySearcher("(&(objectCategory=Person)(objectClass=user)");
  searcher1.SearchRoot = domain1;
  searcher1.SearchScope = SearchScope.Subtree;
  SearchResultCollection results1;
  results1= searcher1.FindAll();
              for (int i = 0; i < results1.Count; i++)
              {
  
  
                  lista1 .Add(results1[i].Properties["samaccountname"][0].ToString());
              }

  Thank you! Any chance you might have this in vb.net? I can translate most of it, but I don't know how to translate the <string> thing.

   Also, how would I find out what to put in the green part? I take it that that part needs to be customized to my AD environment?

   yes, the green part is the connection string to ldap or active directory that you will use.

  You need the active directory server and OU of your domain, a user and a password, minimum with readonly, a common user it's enought to extract the user list.

   

   the list<string> in c# to vb.net :
  

  Dim stringlist As New System.Collections.Generic.List(Of String)()

  where the <string> translate like (Of String), because is a generic list.

  I hope this can help you .

  Thank you for your continued help!

  I translated it to vb like this (you have an item called "dominio" in your c# that I think you meant to be domain1?). My questions follow:

  Dim Domain1 As DirectoryEntry = New DirectoryEntry("LDAP://test.com/DC=dept1,DC=com", "domainadmin", "12345", AuthenticationTypes.ReadonlyServer)
  Dim Searcher1 As DirectorySearcher = New DirectorySearcher("(&(objectCategory=Person)(objectClass=user)")
  Dim Lista1 As New System.Collections.Generic.List(Of String)()

  Searcher1.SearchRoot = Domain1
  Searcher1.SearchScope = SearchScope.Subtree

  Dim Results1 As New SearchResultCollection
  Results1 = Searcher1.FindAll()

  For i As Integer = 0 To Results1.Count
          Lista1.Add(Results1(i).Properties("samaccountname")(0).ToString())
  Next

  I have these questions, if you don't mind:

  1. VS is complaining about the Dim Results1 statement with a blue squiggly under Results1 that says that "Type 'System.DirectoryServices.SearchResultCollection' has no constructors". I've tried rearranging that statement in every possible syntax I can think of, but that hasn't helped. Do you know what the problem is?

  2. Do you know how I can find out what the "active directory server and ou of my domain" is? And how do I arrange that in the code?

  3. What account do I put in for "somaccountname"? How can find a list of eligible accounts?

  Thanks again.

  Never mind my first question about the Dim Results1 statement. I fixed that. But if you could please answer questions 2 and 3, that would help. thanks again.

   if you machine or server are already using active directory, then you can use directly without using a connection string like this:

   

  DirectorySearcher searcher = new System.DirectoryServices.DirectorySearcher("(samaccountname=johndoe)");
  SearchResult result=searcher.FindOne();
  DirectoryEntry dentry= result.GetDirectoryEntry();
  string fullname=dentry.Properties["displayName"].Value.ToString();

  in this case, the samAccountname is the short name o domain user that you are searching, if you need for example, searching all that star with the letter B, you can define a filter in the searcher:

  searcher.Filter = ("(&(objectCategory=person)(objectClass=user)(sAMAccountName=B*"))"); 

  and interate the results:

   System.DirectoryServices.SearchResultCollection userlist=  searcher.FindAll();
   for(int i=0;i<userlist.Count;i++)
   {
      userlist[i].Properties["displayName"].ToString();
   } 
  

    There area a lot of properties in the activedirectory for example:

  TelephoneNumber,IPphone,Mobile ,Department,manager,employeeId,displayName,Name,givenName

  But, you need to check with your active directory admin, in other way, you can extract the properties names with this code snippet:

   

   List<string> propnames = new List<string>();
              System.DirectoryServices.PropertyCollection colprop;            
                  foreach(System.DirectoryServices.PropertyValueCollection elem in dentry.Properties)
                  {
                      propnames.Add(elem.PropertyName);
                  }      

  And check the contect of the string list to view what properties area available.

  Re: List of users from Active Directory?

  Oct 30, 2008 03:55 AM|LINK

  I am trying to traverse through a active directory group in classic asp.

  example

  obj1 = getobject("LDAP://CN=name,DC=,DC=com")
  Dim memName = "test"
  
  for each memebr in obj1.members
      if (memName = obj1.name) then
             flag = 1
          else
            flag = 0
          end if
  next

  it doesn't work. I am trying ti compare the members of "obj1" group to "test". I am not sure what property I need to use to retrieve the member name from an active directory group.

  Please help me.

   

  Thanks,

  Niru

  try this

  Dim ADEntry As New System.DirectoryServices.DirectoryEntry("WinNT://domainname") '"LDAP://domainname") '"WinNT://" & a(0) & "/" & a(1))
  
  
        
  
          Dim adsUser As DirectoryEntry
          Dim i As Int32 = 0
          For Each adsUser In ADEntry.Children
  
  
              If adsUser.SchemaClassName = "User" Then
                  ListBox1.Items.Add(New ListItem(adsUser.Properties("FullName").Value.ToString, adsUser.Name.ToString))
                         
  
              End If
          Next
