C# - Add A User To AD Using System.DirectoryServices.AccountManagement?
May 26, 2009
Using the .net 3.5 framework and C# I'm trying to add a new user to AD from C# and can't find any examples. I see that the PrincipalCollection object has an overloaded 'add' method but can't seem to figure out how it works. Can anyone help?
How create a new user object, add it into AD. Secondly, the user that will be adding in new people may not actually have the security to do this. Is there a way that I can impersonate another user account that will have permissions and add the account that way?

I am using System.DirectoryServices.AccountManagement to try to add a local account to the local administrators group with the following code but am getting the error below on the group.Members.Add(usr) line. Both usr and group are created as objects and if I create a Test group, I can add the user to the Test group. I know the group object is the local administrators group and not the domain group because i changed the description on the local administratrors group and the group object is correct so it appears to be something specific to the local administrators group.

I have a pretty extensive application that has been built to provide SSO to several web applications via OID. The problem is that we have seen some users getting "orphaned" on a role for one of the applications. I have written a method that returns the distinguished name for all of the users with access to that role. To perform the cleanup, I am trying to make sure that the users returned in the previous step actually exist in OID. I have been using the System.DirectoryServices.Protocols.SearchRequest class when searching for users or roles, but it is not working for a distinguished name. Below is my method. It has been changed a couple of times to try different ways to make it work.

I am connecting to a Microsoft Active Directory server in a DMZ from my .net application (asp.net VB .net 4.0). I need to create a new "inetorgperson" in an orgunit called "SingleCustomerAccount".
I have had to use the System.DirectoryServices.Protocols namespace for all the work, because the ADSI classes (System.DirectoryServices namespace) wouldn't work across the DMZ properly.
Anyway it's been working fine connecting to Active Directory on Windows Server 2003 R2; however we're running tests against Active Directory on Windows Server 2008 R2 (2008r2 in native mode for forest and domain) in order to upgrade.
My existing code to create a user does not work.
System.DirectoryServices.Protocols.DirectoryOperationException: The server cannot handle directory requests.

I have computers joined to a domain. I'm writing a desktop application that ask for a username and password to authenticate user against Active Directory.Sometimes, user uses this application on the computer that is not joined to the domain.I'm using .NET 3.5, System.DirectoryServices, and System.DirectoryServices.AccountManagement. Code sample how to authenticate users:
Private Function ValidateExternalUser(ByVal username As String, ByVal password As String) As Boolean
Using context As PrincipalContext = New PrincipalContext(ContextType.Domain, "your_domain_here")
Return context.ValidateCredentials(username, password, ContextOptions.Negotiate)
[code]....
I want to know how to check if user is already logged in on domain computer, then I don't have to ask them log into the application again.
Update:If it can't be done with System.DirectoryServices.AccountManagemen, is there any way to do it?

I'm upgrading my site and pasted some code into a new form in VS 2011 Express beta. I get the standard error below: Namespace or type specified in the Imports 'System.DirectoryServices' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
I went ahead and added a reference for system.directoryservices. Still, the errors remain. I go back to references to make sure it's been added, and it is no longer checked. Repeated tries and the same results.

I've read through what little I could find on system.directoryservices and setting object permissions in AD.What I need to do is grab a DE, read its security descriptor and add / modify it. I need to add permission to another user.
I know how to use the CACLS command for the file system and the concept is basically the same but I dont see any VB (or any ) examples out there that could show me how to grab a distribution list AD object and modify the descriptor so the user has permissions to update the DL (without actually being the owner).

I need to pull back the security descriptors for the active directory attribute "msExchMailboxSecurityDescriptor" on user account objects.So far, all I can find is that I need to use this class to do so, but I cannot find any example code of how to start to pull what I want out using it.I'm restricted to using .Net v2.0.

My application takes the currently logged-in user and uses an a DirectoryServices.DirectorySearcher to pull a few additional detail about them (some properties we have stored in a few custom AD fields, as well as their email address). This works great, though I've always though it was a little slow - my single-threaded code could only make about 2-3 requests/second to AD.
The real problem came when I moved this code to a web server. With multiple simultaneous users, the number of requests/second jumps greatly, and the LSASS.EXE process pegs on my server. I've checked the domain controllers, and they're just fine - the bottleneck is clearly on the application side. I suspect that what's slowing my down is the NTLM/Kerberos challenge/response, and the number of simultaneous requests pegs even the multi-core processor.
Our network policy doesn't allow anonymous reads from AD, so that choice is out. Also, I've tried every member of "AuthenticationTypes" (in the example, I'm using .FastBind), but they all seem to have about the same throughput rate with the same load on the processor.how I might work around this restriction and lower my demands on the processor? Here is the code I'm using - pretty straightforward:
Dim sPath As String = "LDAP://" & stringUserDN
Dim entry As New DirectoryEntry(sPath)
entry.AuthenticationType = AuthenticationTypes.FastBind[code]......

I am accessing active directory with the System.DirectoryServices library, currently in my web layer. However, I'm trying to move a function from a code-behind file to a VB class in another namespace, and I cannot seem to access that class from within that namespace.

We are setting up authentication for our users in our software and were looking at the System.DirectoryServices that other posts have suggested.
Some of our clients use pier to piers (workgroup) networks since they are only 2-3 computers. Will this still work without a true server or domain? One of the workstations will be the file server but only using something like WXP. Will this still work?

Want to change a property of a user in Active Directory programatically. I know I need to use DirectoryServices but I keep getting referral errors.
1. I want to connect to the directory an get the property first.
2. I will then use a evaluative expression to find out if step 3 is necessary 3. Want to change ths property
However, I want to run this from client machines so they won't have permission to modify the schema so I created a new users, is it possible to authenticate with one user and change another's?
Tutorials don't seem to show specification of the user the are changing the context user.

I created a Login system using the Login Form from VB 2010 and connectected to a DB table called "Useri" with 4 columns: "ID_U" , "UserName" , "Password" , "UserType". The login form works to authentificate user, and my application starts. My app has 5 buttons and i want them to be restricted by user type
If admin - full acces
if Operator - 1 button(that leads to a form with 4 textboxes that edit a row from a database)
if guest - 1 button that leads to a form with a datagrid
So, if a guest user clicked a resticted button a msgbox appears.
My login form code looks like this.

I'm trying to create a simple user tracking system so whoever has the program open can see who else has the program open. I know how to retrieve the username and everything. What I was doing was updating (loading and saving) a listbox with a text file on the network with the usernames in it. I can't get it to work right and I think its because the simultaneous opening and saving of the same text file by multiple users. I know this isn't technically the best way to go about doing this but it seemed like it should be the easiest. I don't want to make a huge project out of this because it isn't that important, it would just be nice.

I'm creating an app like a CRM ( Costumer Relationship Managment ) for a school but I have some questions I'd like to be answered.
It will have a main user ( Administrator ) and that user can create another users to access the app. The app will work locally and I would like to know a method to save that information @ localhost without being acessible to edit or view by other users.
Im thinking in a Access DB with all info and then make all information needed. But how to secure it without anyone else could access it or modify id? An encryption method would be the best way?
