Active Directory/LDAP :: LDAP - Can't Find Server?
Aug 10, 2010
I would like to get a persons name from their username - a common query on forums i know, but i haven't managed to get mine working yet.
I currently have this code that I found here:
http://www.vbforums.com/showthread.php?t=612655 (Thanks Chris128)
I have adapted it from VB into VB.net. The page renders but when i enter my username into the Username textBox and hit the submit button (Which calls IsUser) I just get "The specified domain either does not exist or could not be contacted." I have tried lots of other code but I always get this response...

I am new to LDAP so it is a bit confusing for me. I am converting a Legacy application from ASP to ASP.Net. That application is using LDAP so i have to find an alternative/equivalent of this.
My questions are:
1- LDAP is still used or obselete?
2- Equivalent/alternate of this?
3- How it is different from?
4- How can i setup a small test LDAP server if i have to test it locally ?
5- Any examples/source code/tutorials?
I have googled it and i know the basic concept of LDAP but i was unable to get the proper answer for all of the above.

I have developed a web application which has LDAP authentication implemented.When I run the application though visual studio it works fine , LDAP works perfectly and allows if login name and password are correct.
If the same application is hosted on IIS server 6.0, LDAP queries fail to work. What could be the reason for the same ?

I am a newbie on a LDAP, now we want to re-deploy a web application that will validate user name and password with AD in a login.aspx
I had success to check the user and password in VS 2008, but when I publish to server it don't work, (they can login even wrong username and password) I had enable the anonymous access and intergrated windows authentication on IIS. we using authentication mode = windows in our web.config
using something like the following to check the AD account
System.DirectoryServices.DirectoryEntry entry = null;
bool isOpened = false;
bool isSuccess = false;
try
{
string dom = System.Configuration.ConfigurationManager.AppSettings["domain"];
entry =
new System.DirectoryServices.DirectoryEntry("WinNT://" + dom, tb_username.Text.Trim(), tb_password.Text.Trim());
isOpened = true;
Object obj = entry.NativeObject;
but still no luck on IIS server. Would you mind to give me a hand to solve this issue, I had google for a week and still can't solve :(

(&(objectCategory=person)(objectClass=user)(!userAccountControl:1.2.840.113556.1.4.803:=2)(!description=Generic*)(!cn=*-))

I want to store a X509 certificate to a user store in Novell viathe ".NET C# LDAP Library" that Novell has developed [URL]I can store different entries like givenName, commonName, mail, description etc. etc. Everythings works fine :)But I can't store a certificate correctly because the final encoding of the certificate will be failed.I've tried to send the entire certificate as HEX and Base64 in strings and bytes but the final encoding will still be failed.
[Code]....
So my question is:Anyone who knows how I should encode the certificate before sending it?

I'm trying to get the groups a user is member of from an Open Ldap using vb.net 3.5.
Although so far I have managed to connect to the ldap server and get the user's info like sn, givenname, description, mail, adspath,
I have absolutely no information about the user's groups.
My code is like this:
Dim oEntry as New DirectoryEntry
Dim oSearcher as New DirectorySearcher
oEntry = New DirectoryEntry("LDAP://myServer/ou=test, dc=example, dc=com", username, pwd, AuthenticationTypes.ServerBind)
oSearcher = New DirectorySearcher(oEntry, "(uid=" & uName & ")")
oResult = oSearcher.FindOne()
if not oResult is Nothing then
Dim ADUser as DirectoryEntry
ADUSer = oResult.GetDirectoryEntry()
end if
Well, ADUser has no info on user membership whatsoever.
Am I doing something wrong? Should I use System.DirectoryServices.Protocols as I saw someone mentioning instead
of System.DirectoryServices or is .Protocols just for Framework 2.0?

How do I create a top level OU in LDAP directory that has no partition created? In the example below, if strPath ="LDAP://localhost:389" , how do I create the top level OU=MyServer using Directory Services such that my base DN becomes "LDAP://localhost:389/OU=MyServer"?
Example code shown below will throw an exception at CommitChanges() method call. Is it illegal to call Children.Add on the directoryEntry instance that has no base DN? // Construct the binding string. strPath = "LDAP://localhost:389"; Console.WriteLine("Bind to: {0}", strPath); // Get AD LDS object. try { objADAM = new DirectoryEntry(strPath); objADAM.RefreshCache(); } catch (Exception e) { Console.WriteLine("Error: Bind failed."); Console.WriteLine(" {0}", e.Message); return; } // Specify Organizational Unit.
strOU = "OU=MyServer"; strDescription = "AD LDS Test Organizational Unit"; Console.WriteLine("Create: {0}", strOU); // Create Organizational Unit. try { objOU = objADAM.Children.Add(strOU, "OrganizationalUnit"); objOU.Properties["description"].Add(strDescription); objOU.CommitChanges(); } catch (Exception e) { Console.WriteLine("Error: Create failed."); Console.WriteLine(" {0}", e.Message); return; }

I have a web app, right now we use ADFS for SSO. A client says they have other third-party teams use LDAP to achieve this. How do I begin? What will I need to know from them in order to connect? Will I need to ask the user anything when they log in to get the process started?

Using VB2005 and in my code behing I have following query:
[Code]....Value of my select string is: select sAMAccountName, displayName, title, userAccountControl from 'LDAP://DC=Vecelliogroup,DC=COM' where objectCategory = 'User' and title <> ' ' and (userAccountControl <> '66050' and userAccountControl <> '514') and sAMAccountName
like '%vg%'
Getting error:System.Data.OleDb.OleDbException: 'ADSDSOObject' failed with no error message available, result code: DB_E_ERRORSINCOMMAND(0x80040E14).
Now, if I leave out the "title" and the "sAMAccountName" from my select it works fine. I am trying to get records where the "title" is not empty and name matches my prefix.

I m writing a web page to display user name and his contact number.
I m giving user a choice to enter user name once he enter the name i should be able to search in active directory and return all user starting with (inputed name).
DirectorySearcher deSearch = new DirectorySearcher(de);
//set the search filter
deSearch.SearchRoot = de;[CODE]....
Above code needs exact login name like adamjo which is not the purpose.i should be able to display all possible possibilities for example if user enters adam i should give him choice to select whether he want to see adam josef or adam john e.t.c.Is there any property to find first name from active directory?

I wrote a class to pull adinfo and for the life of me I can't seem to figure out why it says "Invalid Login Name" no matter what I type in. If I leave it blank it seems to work properly but it doesn't seem to be actually searching the AD. I'll drop the whole class here, it's being initiated by a button click on an outside form.

Then later on, 2. Our server will upgrade to server 2003 to server 2008.
I would linke to know after doing above two phase will effect on Active Directory code setting in our program.
Can I conver to 1 to 1 withut changing anything in vb.net and server?
