Passing Windows Credentials Through Web Application To WCF?

May 28, 2010

I have a .Net web application which successfully takes on the callers windows credentials (Thread.CurrentPrincipal is my windows user).

Within that app, I call to a WCF service, but my windows identity isn't passed up. Regardless of what I put in the binding:

NetTcpBinding binding = new NetTcpBinding();
binding.Security.Mode = SecurityMode.Transport;
binding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;

Web Forms :: Passing Credentials To IIS "Integrated Windows Authentication" Protected Directory

Sep 8, 2010

I have set up a directory on my IIS web server that is protected by "Integrated Windows authentication". I want visitors to be required to enter a name and password to view files in the protected directory except if they are following a link to files in the protected directory from a certain page on my website.

I am doing this to try to get better protection from search engine spidering than is provided by using a robots.text file.

I am using ASP.NET 3.5 with VB. I am wondering if there is a way to pass the log on credentials to the IIS server via a link, or if there is a way to fill in the name and password for the login screen automatically, or something else that would work. It is OK if the login name and password are visible to the visitors.

Can Open Protected Web Page Passing In Credentials Programmatically

Mar 25, 2010

I have code examples from some of my previous work that help me to post form values to a web page (login credentials) and retrieve the text from that page. Now I want to pass in form values (login credentials again) but actually open that web page in a browser given those credentials.How do I do that? I'm not doing anything nefarious. In our CRM app (home-grown as it is), I want to create a link button that opens our web site's protected products page given the user's credentials (based on the user's login credentials). Normally, I'd copy the user's credentials in our login page which then takes me to the products page.

Security :: Using Different Windows Login Credentials Whithin A Webpage?

Jan 22, 2010

Is the above possible? Basically i need it as I am creating a site where users can upload files to a shared network drive which is secure and has a system account

When a user clicks on upload file, If possible I would like the page to automatically kind of log in with the system account, copy the files and then log off. I know I could achieve something similar mapping a drive but would prefer not to do that for these reasons;

- Security risk if the mapped drive for some reason isnt removed by the code

- User may not have the drive letter free.

VS 2008 - Sending Windows Credentials From Active Directory To Web App

Jan 13, 2012

I've been asked to program a web app for a client's intranet. They want the web app to users in using their Windows credentials. So far in my online research, I've been finding that Active Directories is what I need to access, and that the System.DirectoryServices library provides the tools for doing so. Unfortunately, it seems that one can't get the password from the AD through this route (or through any route). But a coworker of mine tells me there is a way to get AD to pass on the user's Windows credentials (which includes username and password) directly to the web app (so that no one but the web app itself can see it), and that the web app can use those credentials to automatically log the user in.

WCF / ASMX :: Windows Basic Authentication-Credentials Retained For Further Calls?

Aug 25, 2010

I have an XML web service where the authentication used is BASIC WINDOWS. Following is my client code to connect to the service.

[Code]....

Now, the issue is that the client is really authenticated only in the first attempt(First time I execute the code in VS). Further attempts succeed even if the code to assign credentials is commented or even after providing wrong user id/ password. I ensured that the server is hit each time(Just to make it clear that it not just because of client side caching).Is this the behavior of Basic authentication/credential cache. I would prefer the client be authenticated each time he hits the server.

Security :: Require Https To Safeguard Windows Authentication Credentials?

Nov 9, 2010

I have a zealous network administrator who insists that we must use https on an intranet web application in order to safeguard user's credentials. The app is an asp.net web app that uses Windows Authentication to automatically identify users and log them in. There is no login dialog and user's never enter their login or password. The application does not process any confidential data, and the only rationale for requiring https is to "safeguard" users credentials. Additionally he stated that ntlm can be easily hacked.I responded with some information from an MS white paper on Windows Authentication that said it was the recommended way of authenticating users, and that user's credentials were safe because their passwords are not transmitted across the network when the application authenticates them since it sends a hash of the password.

C# - Using .net Credentials To Log In From A WinForms Application

Aug 9, 2010

We have an ASP.net application but some screens are deemed too slow to use by our users.As a result, we are trying to provide a WinForms-based alternative to those data-input centric screens so we can use richer controls like Grids with immediate screen updates and feedback for the user.

Ideally, I would like the users to login to the WinForms application using the same credentials they use in the ASP.net application?

Is it possible?I've found this post ( http://stackoverflow.com/questions/1172069/net-authentication-for-both-web-and-winforms ) but it isn't really answering the question from my point of view... We are not using WebServices, or WCF at the moment and do not plan to use it unless it is really the only way to achieve this.

Security :: LDAP Throws Invalid Credentials With Valid Credentials Supplied?

Feb 1, 2011

I'm working on an ASP.NET project for the first time in about three years; in the meantime I've been working with Python/Django, PHP and Obj-C. Anyways, picked it right back up... except something that is totally killing me right now, and I have a feeling it must be staring me in the face:

I'm trying to bind to an LDAP server, for the purpose of authenticating users. The way it works here is, you bind on your own credentials, use that to find the Distinguished Name of the user you're authenticating, then you bind again on their DN and their password. If the bind is successful, the password was correct and the user can be authenticated.

Here's the problem - the first bind (on the fixed credentials, the ones with the ability to search for users and their subtrees) works fine. The search works fine. The second bind fails, no matter what, with the LDAP error INVALID_CREDENTIALS. This happens even when completely valid credentials are supplied.

Here's the code, with the usernames and passwords redacted, of course...

Security :: Calling A Java Webservice Using Credentials From Application?

I am using Asp.Net application for calling an existing Java webservice. Recently the web service is configured with Security certificates. Now I need to call the webservice using "https:URL .." and by passing the credentials i.e. UserId and Password.

When I call the webservice using [URL] I get the below error. Is the change in my code is causing this error?

Error:Client found response content type of 'text/html; charset=iso-8859-1', but expected 'text/xml'. The request failed with the error message: --

C# - Starting A Console Application From .net Using Authenticated User Credentials?

Mar 9, 2011

I have the following asynchronous controller actions which allows me to start a console application on a remote server. My issue is with regards to the permissions and authentication. I have tried the following, which in my understanding allows the app.Start(valuationDate) to run as the impersonated user. The reason for this is that the console application needs to access network resources and the user of this web app will have the required access rights. (As a side note, the console app runs as a scheduled task without error)

The issue I suspect is that the console app is still run under the IIS app pool identity which causes network resource "Access Denied" errors. The console application itself starts, but the restricted access of the IIS user account causes the failure.

I have tried changing the AppPool identity to run as an authorised user and the process executes correctly. I am hoping for a solution that does not require me to change the AppPool identity on the server.How can I do to start the console application using the authenticated users details?

Controller Actions:

[HttpPost]
public void RunAsync(DateTime valuationDate)
{
AsyncManager.OutstandingOperations.Increment();[code].....
