Why am I getting an exception error when trying to show all users in active directory. What does this mean?
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in System.DirectoryServices.dll
Additional information: The server is not operational.
Code:
'Show all users in the domain
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim domain As DirectoryEntry = New DirectoryEntry("LDAP://domain.com/CN=Users,DC=Domain,DC=com")
For Each child As DirectoryEntry In domain.Children
ListView2.Items.Add(child.Name) 'populate results to a ListView
Next
End Sub
I want to learn how to add/delete/update account (including adding mail boxes for new users). Can someone point to a good book where I can begin from. I want to start with some real basics and build from there.
have a probleme with my search filter, i want to list the users of an organizational unit result.filter =(& (objectClass= user)(ou=dep1)); ====> it didn't work for me
I need to list a group of users, their group name is (IRS Group) to a list group. how to do this. I'm very new to asp.net and dont have much knowlegde about acctive directory.
I have some code that returns my LastPasswordSet date when I use my administrator account on my development machine using localhost but when I deploy to me test server and I get an exception "Object reference not set to an instance of an object" [Code].... [Code].... Any ideas?
I am trying to retrieve all the users from active directory into a sorted list, but for some reason it does not return all the users like myself for instance. It's on a client's ad and there is probably about 1500+ users in AD.
I m writing a web page to display user name and his contact number.
I m giving user a choice to enter user name once he enter the name i should be able to search in active directory and return all user starting with (inputed name).
DirectorySearcher deSearch = new DirectorySearcher(de);
//set the search filter deSearch.SearchRoot = de;[CODE]....
Above code needs exact login name like adamjo which is not the purpose.i should be able to display all possible possibilities for example if user enters adam i should give him choice to select whether he want to see adam josef or adam john e.t.c.Is there any property to find first name from active directory?
The asp.net files are on 2008 server running IIS.From a client workstation (i.e. part of domain) I am running the website.Below code is part of the intranet website:
String ldapPathString = LDAP://abc.au.xyz.com:123/OU=User Accounts,DC=au,DC=xyz,DC=com; if(DirectoryEntry.Exists(ldapPathString)) \at this line, I am getting the error
I am using System.directory services namespace in framework 2 to query active directory. I have used fixed user account impersonisation in the web.config file, find the code:
I have disabled anonymous access in IIS. Also i have given Read & write access to the account tang09 for the website virtual directory and Microsoft.NET folder located in windows folder. But still i get prompted for the domain username and password to access the website.
How can I get a list of users from active directory? Is there a way to pull username, firstname, lastname? I saw a similar post where this was used:
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "YOURDOMAIN"); I have never done anything with active directory so I am completely lost.
I want to use the Domain Users group to show all the users in a dropdown box. For some or other reason I cannot return all the users when looking for everyone under the domain so instead I was thinking of using the domain users group.This is part of my code:
I wonder if it's possible to use .NET to get access to users in Active Directory: - Methods that returns a collection of users belonging to a specific AD group - Get access to AD propterties beloning to the user account, want to check if the user account is disabled or not
I am trying to do something that i am sure has been done before. I have a asp.net pagethat changes a password , and it works fine if I use credentials of a user with rights to a OU that holds the users container. However i would like to have the users credentials
userEntry = new DirectoryEntry(adspath,userid,this.oldPasswordtb.Text.ToString(),AuthenticationTypes.Secure);
be used when executing
userEntry.Invoke("SetPassword", new Object[] {passwd});
currently I get System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) --- End of inner exception stack trace --- at System.DirectoryServices.DirectoryEntry.Invoke(String methodName, Object[] args) at ASP.changepassword_aspx.__Render__control1(HtmlTextWriter __w, Control parameterContainer) in c:usrhtmlexternalChangePasswordchangepassword.aspx:line 128any ideas why that wouldn't work users I assume have right to modify that attribute of their CN right?see code below
I am wanting to make a sign in and out site for reception I have made it so far using C#, I have got the visitor part sorted, how I could let staff choose there name from a list that has retrieved the names from active directory and then that pulls there name into the SQL Database and then adds a row with there name into as including other columns but I can do the other columns.
I'm looking at starting a new web app which needs to be secure (if for no other reason than that we'll need PCI (Payment Card Industry) accreditation at some point). From previous experience working with PCI (on a domain), the preferred method is to use integrated windows authentication which is then passed all the way through the app to the database using kerberos (so the NT user has permissions in the DB). This allows for better auditing as well as object-level permissions (ie an end user can't read the credit card table). There are advantages in that even if someone compromises the webserver, they won't be able to glean any/much additional information from the database. Also, the webserver isn't storing any database credentials (beyond perhaps a simple anonymous user with very few permissions for simple website config)
So, now I'm looking at the new web app which will be on the public internet. One suggestion is to have a Active Directory server and create windows accounts on the AD for each user of the site. These users will then be placed into the appropriate NT groups to decide which DB permissions they should have (and which pages they can access). ASP.Net already provides the AD membership provider and role provider so this should be fairly simple to implement. There are a number of questions around this - Scalability, reliability, etc... and I was wondering if there is anyone out there with experience of this approach or, even better, some good reasons why to do it / not to do it.
I need to get the list of domain usrs. The users not necessorily be on the domain where I am logged in. (e.g. I am logged in on domain "Dom111" but I need the list of users from the domain "Dom222")
I want this information on the basis of following - 1) Name of the Domain 2) A valid User name (of-course with Admin rights for the Target domain) and password
I am trying to use the following code -
DirectoryContext dc = new DirectoryContext(DirectoryContextType.Domain, "Dom222", "Administrator", "password"); Domain domain = Domain.GetDomain(dc); DirectoryEntry de = domain.GetDirectoryEntry(); FillList(de);
Here is the FillList function private void FillList(DirectoryEntry de) { DirectorySearcher deSearch = new DirectorySearcher(de); deSearch.Filter = "(&(objectClass=user)(objectCategory=person))"; SearchResultCollection results = deSearch.FindAll(); //checkedListBox1.Items.Clear(); foreach (SearchResult srUser in results) { DirectoryEntry deUser = srUser.GetDirectoryEntry(); checkedListBox1.Items.Add(deUser.Properties["sAMAccountName"].Value.ToString()); } checkedListBox1.Sorted = true; }
This works fine for the domain where I logged in (i.e. Dom111) but for the other domain (Dom222), while executing the statement - Domain domain = Domain.GetDomain(dc); I am getting the error saying "The specified domain does not exist or cannot be contacted."
Now, For creating the dc if I use following - DirectoryContext dcTemp = new DirectoryContext(DirectoryContextType.DirectoryServer, "Server_dom222", "administrator", "password"); Then everything works fine. But as you can see I need to pass the "Domain Controller (Server) Name"which I want to avoid.
I have a asp.net (3.5) web-app that will be used in an intranet. I need to enforce that users type in their network credentials (windows credentials) before they can log into this application. I intentionally need to disallow Integrated Windows Authentication. I need to authenticate these users against my company's Active Directory, that is obviously on the same network as my .net web app.
I have been reading a bit about Forms Authentication using ActiveDirectoryMembershipProvider - [URL]. I also stumbled upon this - [URL]. Based on what I can tell, both seem to do what I need to get done. Could somebody tell me what are the major differences, pros/cons and when you would use which method? Or are these exactly identical, and both achieve the exact same results?
From the security perspective...what do I need to watch for? I am assuming if I use SSL that will cover me for when I pass the username/pwd to AD for verification?
I'm new to directoryServices and im trying to capture all users in the active directory and their organizational units but i'm having abit of trouble here, i've been reading through the forums and searching online but can't seem to find information that is viable to me.
Here is brief overview of what im trying to do. Im trying to create a datatable where i can insert all the usernames and their ou by capturing the values from the AD but i keep getting alot of duplicated usernames BUT in different organizationalUnits. I've checked the AD, and they do not belong so the following are my codes, but i can't seem to figure out what is wrong.
I ran the following in my active directory server, and it completed successfully.
[Code]....
Can I query from a different server in order to get the active directory users?When I try to run the following query, it says.'Could not find server 'ADSI' in sysservers. Execute sp_addlinkedserver to add the server to sysservers'.I need to be able to query active directory users from a different server as I'll have to do a table join at some point. Right now I'm just trying to get a basic query of users to return.
I am trying to integrate authentication for a cloud-based application with an Active Directory forest behind my cilent's firewall.
I am a Python developer from the open-source world... needless to say, .NET is not my forte and I'm not familiar with authentication technologies provided by IIS/WIF/etc.
I have installed DotNetOpenAuth and gotten the sample MVC OpenID provider working with the included ReadOnlyXmlMembershipProvider.
I have scoured Google for a sample config/implementation or any documentation at all that describes the appropriate membership provider to use. The only thing I have found are hints - "It's included out of the box," or "create a .NET app that authenticates off of AD and expose OpenID."
How can I query off my client's AD? Is there a provider included with DNoA?
I want to know how to do Active Directory Authentication in my intranet web application,
So far I created a simple login page and I am using the login control. my questions are how do I configure the application, how do I interface the login control so it will take the user to next page once they input their usual active directory username and password.
