ActiveDirectory MembershipProvi der not initialized

I am trying to write a change password routine using the new
ActiveDirectory MembershipProvi der. My code is below. I'm getting an exception
saying that my ActiveDirectory MembershipProvi der has not been initialized.
Can you guys point me to something that tells me what I'm doing wrong, please?

bool checkItOut;
string ls_retVal = "";
ActiveDirectory MembershipProvi der obj = new
ActiveDirectory MembershipProvi der();
try
{
checkItOut = obj.ChangePassw ord(as_userName , as_oldPassword,
as_newPassword) ;
}
catch (Exception ex)
{
ls_retVal = ex.Message;
}

I'm trying to setup a web site that uses active directory for user authentication under asp.net 2.0. For testing, I have separately installed two virtual servers. The first is a domain controller in a new forest named VSERVER00 running Windows Server 2003 R2 Standard. The second is an application server running IIS in the same domain, named VSERVER01 also running Windows Server 2003 R2 Standard. The domain is VDOMAIN.local. I have...

Hi all, i'm getting an "object reference not set to an instance of an object" exception when trying to login using the asp:login control and ActiveDirectoryMembershipProvider. What's strange is that if I put a wrong username or password in the connection string the login control tells me this, and doesn't throw the other exception. Any ideas? Thanks in advance

Hi, I am using ActiveDirectoryMembershipProvider for authentication. In my development environment I don't have any Active Directory available for development and test. Basically my development environment is a windows xp laptop. I am trying to avoid running a domain controller on my laptop. What would be the easiest way to develop and test my application without running a domain controller on my laptop?

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
