VS 2008 Active Directory Domain/User/Password Validation Over VPN
Aug 18, 2011
I have a piece of business-soft to make the lives of our employees easier. It's fairly typical, a tabbed-MDI style main form with a load of buttons that activate each of its sub-modules.
I have security set up on it so that someone in sales can't enter the module for purchasing, etc... I authenticate the user by having them type in their network password and check it against the AD server with this function:
'Remember to Imports System.DirectoryServices for this to work
Private Function ValidateActiveDirectoryLogin(ByVal Domain As String, ByVal Username As String, ByVal Password As String) As Boolean
[Code].....

I have a function that works perfectly when I attempt to add a user from the same domain into a group of the same domain.
Function AddUserToGroup(ByVal strUserDN As String, ByVal strGroupDN As String, ByVal strGRPDC As String, ByVal strUserDC As String) As Boolean
Dim oUser As DirectoryEntry
[Code]....
The error is actually being thrown on the Invoke line, but as I said earlier, if the user is in the same domain, this works perfectly.

I have a web form that uses AD to authenticate users. I want to be able to authenticate users with expired password, and redirect them to the password change page after authentication.
if for instance, a site admin reset a users password, I use the method below, to make the user reset their password on next logon.
Public Shared Sub ForceUserToResetPassword(ByVal LDAP_URI As String, ByVal UserName As String, ByVal Auth_UserName As String, ByVal Auth_Password As String)

Is there any way we can verify if a particular domain exists in Active Directory?. I mean, I have an app where admin users can add new domain values in a text box. Before saving the info, I would like to check whether such domain exists in AD.

I need to read the distinguished name of the current user (the one running the program) from Active Directory.I'm warm (I know I should use System. DirectoryServices and DirectorySearcher), but somehow I can't get the code to work properly, nor can I find a working example.Now, after having spent hours searching for examples on the internet, I'm getting quite frustrated with myself, so I turn to you hoping someone can provide an example.Why I need this: when people run this program, it needs to detect which OU they belong to. We have several sites (for example Rotterdam and Amsterdam) and depending on what site the user's OU is, I need to perform some actions. So I hope to derive f.e. "OU=Rotterdam" from their DN.

How I can get around hard coding the Admin user on the page? Would creating an IUSR with a few Admin privileges work?

Currently, users log into a web application with their AD (active directory) credentials which are validated against the AD. Once inside the application, certain users will need to update the AD. When I hardcode a username/password, I am able to update the AD, however when I try to force the object to use the logon credentials or if I don't specify the username/password, it throws an error. Obviously due to security concerns, I do not want to hardcode credentials.

I wrote a sub that would update an Active Directory user's phone numbers using the lines below:
SetProperty(dirEntryResults, "telephoneNumber", strPhoneNumber)
SetProperty(dirEntryResults, "mobile", strPhoneMobileNumber)
The telephone number updates successfully but the mobile number never updates although the strPhoneMobileNumber variable has a valid phone number value. The code executes without any errors. What do I need to do to change the mobile number?
Sub UpdateUserAcct(ByVal userLogin As String, ByVal strPhoneNumber As String, ByVal strPhoneMobileNumber as String)

Dim dirUserSearcher As DirectorySearcher = New DirectorySearcher(dirUser)

I am using windows 2008 R2 Server and trying to Add a user in active directory .
I am able to save user ID of length less than 20 Characters.But when I am trying to increase this value to 30 characters then I am getting the error.
"System.DirectoryServices.DirectoryServicesCOMException (0x8007001F): A device attached to the system is not functioning. (Exception from HRESULT: 0x8007001F)"
This error when I searched on net give me various links saying that:
(a)verify if the issue is caused by the length of sAMAccountName
(b)The document of SAM-Account-Name also indicates that the length of it should be less than 20 characters.
I am using the code below to add user in Active Directory
public static void AddUser(ADUser adUser)

I have multiple web applications that I've built for our intranet. I wanted to allow users to not worry about logging in, so these apps pull the currently logged on user when they hit the site. I used this code for this to happen:
Dim userName As String = User.Identity.Name
CurrentUser = userName.Substring(userName.IndexOf("") + 1)
This works like a charm, no issues here. The next step is to query Active Directory for that logged in user to pull various information. How I currently have it coded, it works like a charm on the devleopment side (typical because I'm not running IIS).The problem becomes when I publish it to my IIS server (Windows Server 2008 R2 running IIS 7.5), I get error messages that point to the specific line in my code that queries Active Directory. The interesting part is these apps were working great last week. They broke after my server admin did the latest batch of Windows Updates (please note, I am running them using .Net Framework 4.0)Before I had each app setup so that Windows Authentication was Enabled, the other Authentication types were disabled. For providers, Negotiate is #1, NTLM is #2. For Advanced Settings, Extended Protection = Off, and Enable Kernel-mode authentication is checked.
[code]...
In doing this I also removed the string that was higher up in my web.config section. This did not work either (fyi, this was a great reference[url]I then tripped across this article: [url] which seemed to be a similar situation. This article eventually referenced "Double Hops", after looking into this and trying a few things, this didn't solve my issue either.Next StepI am going to try a new IIS 7.5 implementation on a different Server 2008 R2 system and essentially start from scratch, to see if the problem recreates or not.

Currently a user right clicks on a template and chooses Copy, then enters info for new user.user is then created just like the template user. How can I perform these operations using the VB.NET framework and Active Directory or Account Management DLL's?
