Using LDAP To Get All Users In Active Directory?
May 1, 2009
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)

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 :

Dim pinger As New Net.NetworkInformation.Ping
Dim usr As DirectoryEntry
_de = GetDirectoryEntry()
If _de Is Nothing Then

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

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

'To retrieve list of all LDAP users

Then i get the "find people" box pop up. So i know i have the correct LDAP but not sure why the other information is preventing it from working..

I need to add multiple users to active directory in vb.net what would be my best way to do this? Although i see some dotnet classes for them its hard figuring this out for my first time. Mostly what must i be aware of when trying to add them? Multiple opinions on the matter would be fine but I really just wish to add users with basic information like firstname and lastname and maybe to specific group.

I'm trying to pull the username of every user available through active directory. Here is the code my colleague first tried to use, but this method is burning all of the memory out and throwing out of memory exceptions. Is there a quick alternative?
Dim userList As ArrayList = New ArrayList
Dim sPath As String = "LDAP://test.ca/OU=foo,OU=bar,OU=foobar,DC=test,DC=ca"
Dim myDirectory As New DirectoryEntry(sPath, Nothing, Nothing, AuthenticationTypes.Secure)
Dim mySearcher As New DirectorySearcher(myDirectory)
mySearcher.Filter = ("(objectClass=user)")

I created a piece of code to create users in our active directory (2003) Everything is working OK and all attributes are set correctly. Only if i logon with a created user i do not get the mapping H: to the homedrive. When looking in ADUC the path to the homedir is correct. Also permissions on the homedir are correct and the user is owner of the dir.
If i correct the path in ADUC to another path and change it back again to point to the homedir the drive mapping is made correctly, so it look's like some kind of attribute is not set correctly. I used ldp.exe to view the created user's attributes before and after modifying the path but don't see any difference.
Tried to create the dir before and after user creation but that's not making any difference.

I have this problem that just recently started happening.I've created this snippet that isolates the problem, which is basically, the same VBScript that used to return all of my users from Active Directory, now only returns the first 100 users.If I filter by group, then i get all of the groups (which is more than 100).The problem started happening last November, then went away for a while and has come back.The server guys tell me that nothing should have changed there.When I run this script for various domains, i get a numbered list of just the first 100 users.I'm running this on IIS (which hasn't changed)[code]

I'm writing an application that will add users to Active Directory. I'm trying to use this code to connect to the "Users" shared folder in AD
[URL]
However it adds the user in with the shared folders, instead of within the "Users" shared folder. Shouldn't CN=Users mean it will add it to the "Users" folder?

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".
