I'm writing code to connect to my Active Directory server using LDAP. I can connect using
LDAP://celtestdomdc1.celtestdom.local

Am I using the wrong syntax or something?

there is a difference between the implementation of the FindAll() method on the DirectorySearcher object in C# and VB.NET? From my understanding they both get "compiled" to MSIL and get processed by the CLR the same way. Going against our ADAM/LDAP system the below C# code throws an error and the below VB.NET does not.Here is the C# exception stack:
at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail)
at System.DirectoryServices.DirectoryEntry.Bind()
at System.DirectoryServices.DirectoryEntry.get_AdsObject()
at System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne)
at System.DirectoryServices.DirectorySearcher.FindAll()
Here is the C# error:
System.Runtime.InteropServices.COMException was unhandled

View 5 RepliesI have not been able to successfully verify a user with LDAP for an ASP.NET web application. I have done so on our own network against Active Directory, but this is against a server outside of our network that is OID (Oracle Internet Directory).Usually, I use the following code with no problem.
Dim myDirectoryEntry As New System.DirectoryServices.DirectoryEntry("LDAP://1.2.3.4:999/OU=SomeOU,DC=Something,DC=com")
myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Sealing
myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Secure

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?
I need to query AD to work out what access a user has to my application.I have 7 AD groups (FTP1 to FTP 7), these groups can have other groups added so I'm using GetMembers(True) which is recursive.The below function works great but it's a little slow, is there any obvious changes I can make to speed it up?[code]
View 6 RepliesIn an application I'm working on I am using the Environment.UserName Property to get the logged on user's username. Is there a way to convert this to the logged on user's REAL first name and last name that is associated with it in Active Directory? I'd like to avoid having to connect or query Active Directory directly if possible (as this is a corporate domain). I also wanted to avoid hard-coding lookups into the app itself, as the users of the application will change over time. Would a "users" external file (Text, XML, csv) be better for this?

I've never scripted anything before,Using Listing 6 from [URL].. I have amended the script for my domain, and the response is correct for the Default Domain Policy. However we have a different password policy for an OU within the domain, so I amended the script as follows:
[Code]...
I hoped this would pick up the maxPwdAge which is set for this OU, but the response I get says the max password age is 0. This is not the case. The max password age is 2 (doing some testing), but it can't see this. Have I done something wrong, or can this script only see the Default Domain Policy, and not the individual OU policies?
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.
[Code]...
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'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 am trying to get all the users under a tree from AD with the following

How can I access the current user information via LDAP and VB.Net 2.0*? I found a vbscript that works, but I'd rather have it done in .net
Dim objSysInfo = CreateObject("ADSystemInfo")
Dim strUser = objSysInfo.UserName 'returns current user account
Dim objUser = GetObject("LDAP://" & strUser) 'queries active directory for user account
I'm using the framework 2.0 because it is for more likely in my XP/Vista/7 World to have 2.0 installed than 3.5 or 4.0
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 have been trying for days to populate a combobox with user names from our LDAP. I can not seem to get this to work however I am really new to LDAP also. Here is my code...
[Code]...
I am trying to set up a new internal system for my client currently, they insisted on integrating the login with AD, which makes sense, and i have managed that with no problem. However what i also want to do, after authentication, is to store some user details / attributes as session variables. I have the following code to aithenticate the user:
'this function authenticates against AD - very simple and works nicely.
Function AuthenticateUser(path As String, user As String, pass As String) As Boolean
Dim de As New DirectoryEntry(path, user, pass, AuthenticationTypes.Secure)
[code]....
which works nicely, and once the function returns me a True, i set Session("LoggedIn") as True.what i need to do is (hopefully within the above function) save the user's name, and 2 other custom atributes from within the user's AD profile.How would i access those (hypothetically)

I am very new to NTLM/LDAP and trying to authenticate using NTML running on a local machine. The code provided by Microsoft [URL] seems to work, I just do not know how to connect to it.
I know that the authentication service is running because Contos 8 has been set up to authenticate using NTLM and it is working. I just do not know what the "connection string" should be:
I am trying: LDAP://CN=machinename with no luck.
Dim adAuth As LdapAuthentication = New LdapAuthentication("LDAP://CN=LOCALMACHINENAME")
Dim entry As DirectoryEntry = New DirectoryEntry(_path, domainAndUsername, pwd)
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.

I'm my program always fails at the same line:
objUser = GetObject("LDAP://CN=" & strUser & "," & ADPath)
If I reduce the code down to just this:
objUser = GetObject(), I still get this exception:
"Cannot create ActiveX component."
After googling this for about 18 hours, I found that it could be because of a permissions issue. I am a local administrator on the PC, so I believe that takes care of permissions. Secondly, I discovered that the dll file might not be registered. I tried to use the following command to register the dll file I think is being used:
regsvr32 "c:windowssystem32wldap32.dll"
It says the following:
Error - The module "C:windowssystem32wldap32.dll" was loaded but the entry-point DllUnregisterServer was not found. Make sure that "c:windowssystem32wldap32.dll" is a valid DLL or OCX file and then try again.So no matter what I try to do, I keep getting this unhandled exception error that says that it cannot create the activex component. What do I need to do to be able to use this getObject() command? Is the problem with LDAP? What activeX or DLL file is failing if even just running the getObject command gives an exception?
