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.
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.
I have an intranet web application, where i have windows authentication = true in web.config. I hear from end users that the website is aksing for their login credentials and they don't like it. By the way i am getting theusername from HttpContext.Current.User.Identity.Name and Domain Name from Mid(UserNameID, 1, InStr(UserNameID, "") - 1).In IIS, anonymous access is unchecked and Integrated wnidows authentication is selected.
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.
Is it possible to bypass the NT challenge login, and just have a standard webform login, then authenticating programtically as that user and passing those credentials manually to my connection string so that the database sees me as that user?
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.
I want to implement a custom authentication in my application using the basic authentication schema. I've configured it in the Web.config and enabled the basic authentication in the IIS, but when I try to open the service in the browser... appears a login dialog... what do I have to put ther? Besides, I want to control the authentication, I mean, I want to check whom is allowed in my custom list... where is it looking now?
When I use the WebRequest class, I'm getting a "401 - Unauthorized":
req = WebRequest.Create("http://localhost/RESTfulService/Service1.svc/Test"); req.Credentials = CredentialCache.DefaultNetworkCredentials; WebResponse res = req.GetResponse();
What do I have to do for implement a custom basic authentication? (I cannot use membership providers).
I have just started building an asp.net web service with visual studio 2005. However whenever i try and run the site i get this message, saying "debugging failed because integrated windows authentication is not enabled". I am at a loss of how to correct this problem.
This could be very straight forward for some of you, but I got caught up. I am doing very simple test - browsing from IIS Manager to see the default page or "under Construction", however I am being challenged to provide my login credential . When I provide my login credential, I am able to see the default page. I wanted to see the default page without providing my credential since Enable anoymous access + basic authentication I am simply wanted to see the default page asit is working on other servers except this one. I have included screen print to make sure may question is clear.
I have an Intranet which is on IIS 7.0. I want to authenticate my users and know who is logged in. What options do I have to set in IIS Authentication part that my users do not need to type their user name and password to login to Intranet. I have set the Authentication to Basic and Impersonation, but it is asking user name and password.
I need to create an application (ASP.NET or WinForms or Windows Service, not sure) that needs to make a call to a url including username and password for basic authentication and have the url return a csv file. I then need to use the csv file in the application. I don't know how to do this. How do I call the url in my app. There can be no user interaction, it needs to be completely automated in the returning of the csv file.
I'm looking to implement my own basic webforms authentication. I don't want to use the 'membership' features in this case because I don't want to modify the database schema with all the membership elements that I won't use, and I don't need to support users across multiple applications. I want to wind up with one simple 'users' table that has username, password, passwordSalt, and several other fields to support custom user attributes specific to this application.
but it's rather dated... is this still valid? I'm looking for guidance on what I need to do to implement a custom webforms auth solution. A very basic skeleton I can expand upon, or a good tutorial/guide that illustrates the necessary parts... just the basics..
I'd like to use built-in IIS authentication with non-Windows accounts. There's this module that does that for basic authentication, but it in fact does both the authentication and credentials checking.The problem is I also need to support digest authentication and I could try to do it, but it would be a lot of hassle - I need to generate challenges ("nonces") securely, store them and check for replays, etc. - lots of things I can screw up and make determined attackers happy. So I'd prefer to reuse the digest authentication functionality in IIS, but use my own module for credentials validation. How can I do that?
1) I have an ASP.NET website which is the main entry point in the application.This website uses Forms authentication, which validates credentials (username/password) against a database. 2) Once logged on the website, the user is displayed a page containing several links which point to a Sharepoint 2007 application, where authentication is managed by an Active Directory. 3) Every user in the Active Directory is duplicated in the database managing the ASP.NET website authentication.
