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 Message="The parameter is incorrect.
I have a code that I found as a VBS and ported it to VBA and works perfectly, but I am now trying to run on VB.NET 2010 but am getting a Path not found error. I am trying to get the complete name and e-mail from the Acitive Directory from the current user.[code]
I 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://126.96.36.199:999/OU=SomeOU,DC=Something,DC=com") myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Sealing myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Secure Try
After that, I haven't been able to find a method to verify a user's log in information with their password and then pull back some information.
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]
I'm writing code to connect to my Active Directory server using LDAP. I can connect usingLDAP://celtestdomdc1.celtestdom.localbut I can't connect usingLDAP://celtestdomdc1.celtestdom.local/CN=Users;DC=celtestd
In 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 have the need in my program to get the list of user logon names in a group. This is what I have so far but it only returns all the users...which I need cut down to those in a group, of which i have the name of.
Option Explicit On Imports System.DirectoryServices Imports System.DirectoryServices.ActiveDirectory
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:
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?
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:
Friend Function ResetPassword(ByVal OldPassword As String, ByVal NewPassword As String, ByVal UserName As String) As String ' Resets a users domain password
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
I keep getting this error:Quote: There is no such object on the server. on the line: For Each account As SearchResult In AccountSearcher.FindAll However, if i modify the DirectoryEntry to this: Dim RootEntry As New DirectoryEntry("LDAP://OU=Mayor,DC=c*******gatn,dc=gov", "myusername", "mypassword") It works but with the wrong returned user data....
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?
Using vb2005 and .Net 2.0. I've been trying for some time to get my query to work. I've posted my issue on several forums but no one been able to asssist me. From code behing I need to query Active Directory and have following issues:
1. I need to select only where "title" is empty and 2. I need to do a LIKE on sAMAccountName
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)
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 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.
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:
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?
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?
LDAP check dir exists when authentication is none Experts I am try to check if an LDAP path exists and the following code works fine if the AuthenticationType is not none. How do you check this if the LDAP does not use authentication?
Ok, I have this code... and it works. If I want to add it to say... a checkbox or something of the sort.
Public Sub groupaddarray() Try 'Alpharetta Staff If Form1.CheckBox23.Checked = True Then Dim grp As IADsGroup
My question... how can I double click the listbox, and then it keeps adding these groups to say... another text box, and when I click add groups it will read the textbox, and add multiple groups instead of just the one?
I'm struggling to return user details from AD using LDAP, after i have authenticated that the user exists. I am using a simple auth method as follows:
Function AuthenticateUser(path As String, user As String, pass As String) As Boolean Dim de As New DirectoryEntry(path, user, pass, AuthenticationTypes.Secure) Try Dim ds As DirectorySearcher = New DirectorySearcher(de) Dim result As SearchResult = ds.FindOne()
the problem is that "distinguishedName" returns "DC=our-domain,DC=co,DC=uk" and "name" returns just "our-domain", not the name of the user that has just been auth'ed
Note: the displayName.text outputs are purely for debug purposes.I have tried various combos of requests but nothing seems to return USER details. ETA: to the security police: this is all within a https connection, I'm not sending passwords about in plain text!
Our company is developing software projects that use a users windows username/password for program authentication. Our programs encrypt the username /password, send them to a web service. The web service decrypts the username/password and authenticates the user against our LDAP using the System.DirectoryServices namespace. This works well. There are two methods, one that validates the user and passes back the user's LDAP info in a datatable, the other passes back a boolean that indicates the user is on the domain. This is working just fine. Over the 4th of July weekend, our domain server hung. While it slowed down the login process for windows while it re-routed to a secondary domain server across the country, all our programs could not validate the users because our local domain controller was down.So I have been asked to update the web services to include a list of domain controllers that can be used if the local one is not available. Below is a snippet of code I use to validate a user:
The getinfo function uses the directory services to create an LDAP entry, then do a search based on the account name (windows username) and populates properties for common LDAP information. How can I extend this function, or re-write it, to run down a list of domain controllers found on the network to validate a username? I was thinking of putting the domain in a database, but that requires administration as they change. Is there a way to cycle through the local domain controllers listed on the machine?
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
