Security :: Authenticate Against The Active Directory When The Site Is Hosted Remotely?
Mar 25, 2011
I am trying to develop a internal corporate portal that will be hosted external either on company leased decicated server or by hosting service like godaddy. The company portal is going to have links internal and external resources like Outlook Web Access and Sharepoint, Great Plains, our CRM software, etc, etc. I am basically creating intranet site for the company but the intranet is going to be hosted externally.
How do I authenticate user against the Active Directory, when the intranet site is hosted remotely?

How to authenticate an user against a particular OU in Active Directory. If the AD holds 50 OUs I don't want to look into all 50 OUs , instead it should look into a particular OU( for eg: OU=dotnet users) to authenticate the user.

I am trying to build a web app for an intranet site that for security reasons needs to make the user type in their Windows or Active Directory username pwd manually. I have previously worked with Integrated Windows Auth but in this case, we do want them to use type in their AD credentials.
I have been trying to look up how to do this and frankly I am a bit lost. It should be a fairly straightforward task and am hoping you can point me in the right direction, with some tutorials or examples. We will be using SSL so, dont have to worry about passing pwd in cleartext over the wire.
My environment is visual studio 2008 in C#, .net 3.5 if that matters.

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 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 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:
<identity impersonate="true" userName="enterprise ang09" password="Telcome123"/>
<authentication mode="Windows"/>
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.

I am a newbie on a LDAP, now we want to re-deploy a web application that will validate user name and password with AD in a login.aspx
I had success to check the user and password in VS 2008, but when I publish to server it don't work, (they can login even wrong username and password) I had enable the anonymous access and intergrated windows authentication on IIS. we using authentication mode = windows in our web.config
using something like the following to check the AD account
System.DirectoryServices.DirectoryEntry entry = null;
bool isOpened = false;
bool isSuccess = false;
try
{
string dom = System.Configuration.ConfigurationManager.AppSettings["domain"];
entry =
new System.DirectoryServices.DirectoryEntry("WinNT://" + dom, tb_username.Text.Trim(), tb_password.Text.Trim());
isOpened = true;
Object obj = entry.NativeObject;
but still no luck on IIS server. Would you mind to give me a hand to solve this issue, I had google for a week and still can't solve :(

I have developed a web application which has LDAP authentication implemented.When I run the application though visual studio it works fine , LDAP works perfectly and allows if login name and password are correct.
If the same application is hosted on IIS server 6.0, LDAP queries fail to work. What could be the reason for the same ?

Then later on, 2. Our server will upgrade to server 2003 to server 2008.
I would linke to know after doing above two phase will effect on Active Directory code setting in our program.
Can I conver to 1 to 1 withut changing anything in vb.net and server?

I am updating some CS code that was written in 2004, and that references some assemblies which extract user data from AD by query filtering on the user's title. I can't test my updated code in VS2010 because the assemblies no longer compile - the references are no longer valid (I can't create a DirectoryEntry or DirectorySearcher) so I need to work out how to replace the code with current directoryservices.accountmanagement namespace properties and methods. I have searched around but don't seem to be getting anywhere. give me some code that will work with vs 2010 to replicate the following:
