Dec 1, 2009I 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.

Apr 13, 2010I have a VB Web Site project that has recently (and mysteriously) stopped importing the "System" namespace by default.
I'm having to either place an Imports System line at the top of each code behind, or preface everything with System, which is fairly annoying, not to mention redundant. I can't for the life of me figure out how to get the System namespace back to being imported by default.
I've already checked to see that WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGweb.config contains the <add namespace="System"/> line--it does. That was my best lead.
I have references to several namespaces within the System namespace in the <assemblies> node (e.g. System.Design, System.Web.Extensions of my website's web.config. There is no <namespaces> node. This has not been changed recently.

Differences About Importing Namespace In C# And VB?
Sep 16, 2011In VB, when we adding a new references - in my case web references -, it simply type namespace followed by the class name to make a new object.For example:
Dim obj As NamespaceName.ClassName = New NamespaceName.ClassName
Then I apply this concept in C#. So my code will be:
NamespaceName.ClassName obj = new NamespaceName.ClassName
...and it doesn't work.Actually, is there any difference about Importing Namespace between those two?And also can you give me a little explanation about Project-Wide Default Namespace Imports in VB?
UPDATE:My point is why "In C#, When I've typed NamespaceName, the ClassName was not listed in the Intellisense?".However, it did well in VB, do I have to import something?Maybe, there is something to do with the term "Project-Wide Default Namespace Imports". (CMIIW)
Can't Add Reference System.directoryservices
May 21, 2012I'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.
System.directoryservices And ActiveDirectorySecurity?
May 8, 2009I'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).
C# - Add A User To AD Using System.DirectoryServices.AccountManagement?
May 26, 2009Using 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?

View 1 RepliesGet User By Distinguished Name Using System.DirectoryServices.Protocols
May 7, 2012I 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.

System Namespace Conflict With Sibling Namespace
Nov 16, 2011This class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

Jun 29, 2010I 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.

C# - Check If A User Is Already Logged Into Domain With System.DirectoryServices.AccountManagemen?
Nov 9, 2010I 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?
System.DirectoryServices Pegs Processor When Multi-threaded - Can I Lower The Burden?
Feb 23, 2009My 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)

System.DirectoryServices.AccountManagement - Error Adding User To Local Administrators Group But Not Other Groups?
Apr 30, 2012I 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.

Create A Loop That Reveals A Certain Number Of Labels?
Apr 9, 2012I want to be able to reveal and then populate a certain number of labels. The inefficient way would be to SELECT CASE on the number of labels required and then populate these in turn. I am looking for something like this:
For i = 1 to RequiredNumOfLabels
Label & i.visible = true
Label & i.text = DataTable.Rows(i).Item(2)[code]......
is the problem as after the line is executed, lbl still equals nothing.The reasoning behind it is that I was trying to create an invoice generator in vb.net and I was hoping that this would be a simple way to do it - count the amount of items in the order, populate the labels with the names of the items, reveal that many labels.
