Forgot Active Directory Password - Reset Using LDAP
Apr 21, 2011
I'm working on a web based "Forgot Password" to reset AD passwords, using LDAP. Well, I can unlock the user, but not change the password.
Here is my function :
Private Function ChangeLocalUserPassword(ByVal User As String, ByVal Pass As String) As Boolean
Dim pinger As New Net.NetworkInformation.Ping
Dim usr As DirectoryEntry
_de = GetDirectoryEntry()
If _de Is Nothing Then
[Code] .....
How I can get around hard coding the Admin user on the page? Would creating an IUSR with a few Admin privileges work?

I'm designing a program to search through all users in Active Directory and get the lastLoginTimeStamp attribute. From there I'm having a report(.csv) genererated based on who hasn't logged in 30,60, 0r 90 days. I believe I'm having a problem in my loop somewhere. My code works when I LDAP an OU with users inside but when I try to get it to seach subcontainers I get several exceptions thrown at me. Here is a sample of my loop code:
'Initialize and open report file
ReportFile = My.Computer.FileSystem.OpenTextFileWriter(My.Settings.ReportsPath & "LoginAuditReport.csv", False)

1> take a request... ie. First name, Last name, or login ID and Search AD Path can be hard coded so entire forest is not searched.
2> List all entries found
3>once the correct user is selected I need to pull First, last, middle name and , Email , Phone number , @ and GUID for that user.

I have a WinForms app with SQL05 backend. It has a standard Login window where users are required to supply a username/password. This is validated using my own code and sprocs. Now one of my big clients has scared the bejezus out of me by saying, "Hey Chris, I want you to change your app in line with all our other IT systems so that users can use their common username and passwords with authentication against LDAP". :confused: Having had a moment to reflect, I have some questions (some very noob in nature!)
1. Is this requirement a big deal? :) Or straightforward to implement?
2. Does this mean that when user's double-click my app icon on the desktop, the authentication automagically happens without the need for a Login screen?
3. How on earth can I test this. My dev environment does not use AD, but I do have SBS2003
4. Can anyone point me to good resources about this on the web?

I'm trying to obtain the Terminal Services Profile Path for a user using VB.Net and the System.DirectoryServices.DirectorySearcher. I am able to get the user object's first name, last name, city, state, zip, etc. However, there is one property that eludes me. I cannot manage to find a way to get the terminalservicesprofilepath property.This is how I did it in VB6 and it worked perfect:
visual basic code:
Dim TSPath as string
Dim FirstName as string

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)

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.
Error - System.DirectoryServices.DirectoryServicesCOMException: An operations error occurred.

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

how I would go about creating a forgotten username/password button
Ideally, I would like it to email the user their log in details after they answer a security question
The only real problem i have is how would i send an email containing the required information after a series of events is triggered
The log in details will be stored in a database, most likely Microsoft access

I have 2 questions here.
1. I would like to know how the attributes of an object in LDAP can be fetched using vb.net
eg here i want to get the properties of user with id saechira.[URL]..
2. I have to perform the authentication of username and password using our LDAP server. I have tried to use the below code. When I try to execute this code it say "Logon Failure: Unknown user name or bad password". Is it because of any invalid parameters, can anyone Please let me know why the authentication fails.. The username password and the domain are all correct. why does this error occur.

Long story short I have a situation where some users have access to two domains that do not trust each other. They log into one domain and their user ID's are identical on the other domain. So when they change their password on the first domain they need to call into tech support to have it reset on the second domain. I'm writing a app that checks if they have access to the first domain but not the second and if this is found to be true it prompts them for the new password to update the second domain.
Here is where I am stuck. The following code works GREAT but I need it to be more flexible:
Code:
Friend Function ResetPassword(ByVal OldPassword As String, ByVal NewPassword As String, ByVal UserName As String) As String
' Resets a users domain password
[Code]....
The issue is the CN is different between domains (one is first name last, other is last name first) so I need to search by UserID which is the same between the two. So I tried searching by sAMAccountName but it says object not found. Also I need to be able to search the entire Super Corp OU. When I get rid of the extra OU's the search also fails
So I need to search LDAP for sAMAccountName anywhere in OU=Super Corp. How can I do this? Every combination I try seems to fail yet if I hard code it like the above example it works great. The idea is to replace CN=John Q. Public with sAMAccountName=" & username & " to pull jsut that user on the fly.
If it matters all clients are XP SP2 or higher, both domains are Server 2003 or higher. VB 2008 SP1. The error message when a different search is done is a "Object not found".

I need to authenticate a user against LDAP/AD (windows 2008 r2) so I can leverage the domains password rules etc... I found code that will allow me to validate a users ID and Password entered into a form (using System.DirectoryServices.DirectoryEntry) but my problem is if the user enters an invalid password more that AD is configured to allow, the account gets locked out. Is there anyway around this?

I would really welcome some help with this issue. We have a php code that works and connects to the LDAP. When I try to connect using VB.NET 2010, it fails to bind with logon failure unknown username or bad password. Below is the connection information. When I talk to the folks who run the ldap server, they say I am binding sucessfully, below is the log file for the sucessful bind? If I continue and try to execute a search I don't get any results. The server is running openLDAP ver 2.3.39 on a linux server, server requires connection on port 636 for secure connection, or 389 for anonymous.
