Active Directory/LDAP :: LDAP Authenticate AD Fail On IIS (SSL), But Successful In VS2008?

Mar 31, 2011

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 :(

Active Directory/LDAP :: How To Fetch The User's Domain Information

Nov 17, 2010

my website need a function to allow domain users jump over the login page and directly access the contents of the site. but for other users which there are not in the domain or they are not the member of the domain then they have to login the website through the login page.

this is different with ask user login to the domain through a login page. the website must distinguish is the user a domain user and the user name in the domain or not when the user first time access website.

Active Directory/LDAP :: Get User Groups From Open Ldap Using Vb.net

Apr 1, 2011

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?

Active Directory/LDAP :: LDAP Query To Check If An User Is In A Group Or Not. Creation Of A Portal | Query = Null

Jul 7, 2010

I'm working on a portal, and I need to check users conection on the ldap.

And if users are members of a special group then it works.

I've exactly used this link to make it works : http://msdn.microsoft.com/en-us/library/ff649227.aspx (almost work)

My point is : my ldap path seems good, no error anymore, when I log with my username and password.But when I querry it, it returns null, but I'm sure my user is in the group :

// Bind to the native AdsObject to force authentication. Object obj = entry.NativeObject; DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(SAMAccountName=" + username + ")"; search.PropertiesToLoad.Add("cn"); SearchResult result = search.FindOne(); if(null == result) { return false; }

I'm a normal user, i test with my account. I'm a member of the group that I'm looking for.

Active Directory/LDAP :: Get The List Of Users From Other Domain

Aug 4, 2010

I need to get the list of domain usrs. The users not necessorily be on the domain where I am logged in. (e.g. I am logged in on domain "Dom111" but I need the list of users from the domain "Dom222")

I want this information on the basis of following -
1) Name of the Domain
2) A valid User name (of-course with Admin rights for the Target domain) and password

I am trying to use the following code -

DirectoryContext dc = new DirectoryContext(DirectoryContextType.Domain, "Dom222", "Administrator", "password");
Domain domain = Domain.GetDomain(dc);
DirectoryEntry de = domain.GetDirectoryEntry();
FillList(de);

Here is the FillList function
private void FillList(DirectoryEntry de)
{
DirectorySearcher deSearch = new DirectorySearcher(de);
deSearch.Filter = "(&(objectClass=user)(objectCategory=person))";
SearchResultCollection results = deSearch.FindAll();
//checkedListBox1.Items.Clear();
foreach (SearchResult srUser in results)
{
DirectoryEntry deUser = srUser.GetDirectoryEntry();
checkedListBox1.Items.Add(deUser.Properties["sAMAccountName"].Value.ToString());
}
checkedListBox1.Sorted = true;
}

This works fine for the domain where I logged in (i.e. Dom111) but for the other domain (Dom222), while executing the statement - Domain domain = Domain.GetDomain(dc); I am getting the error saying "The specified domain does not exist or cannot be contacted."

Now, For creating the dc if I use following - DirectoryContext dcTemp = new DirectoryContext(DirectoryContextType.DirectoryServer, "Server_dom222", "administrator", "password");
Then everything works fine. But as you can see I need to pass the "Domain Controller (Server) Name"which I want to avoid.

Active Directory/LDAP :: Create Top Level OU In LDAP

Feb 3, 2011

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; }
