Security :: Force Https Before Windows Authentication?
May 10, 2010
Okay, so I have a site which I'd like to use my SSL certificate for always. So I want all users to be forced to the https version of any url they are directed to.I used this code in my global.asax file:
[Code]....
I've also tried it in the 'Application_BeginRequest' function also. Basically, I have two directories that are secured via Windows Authentication against my domain. if you browsed to the directory (ex. http://www.domain.com/secure) it tries first to authenticate
then redirect to https://www.domain.com/secure. In this case it will ask for credentials twice one right after the other. Is their a way I can have the user redirected before Windows Authentication kicks in?
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.
I am trying to force to show to the Logon popup when the session is timeout in Integrated Windows Authentication Enabled website. The session_timeout is firing during the session timeout, but the User.Identity.IsAuthenticated is true. How force to use the Windows Logon Screen when the session is timeout.
I have an silverlight application configured with windows integrated security. I would like to emulate the "Sign in as different user" functionality I would like to give the user, the option to click a button and show the windows authentication login window, so that the user can enter the "User name" and "Password" again using another domain account. (btw i found this question on another site but with no answers, I need the same thing so i copy/pasted a bit)
first i want to know most of the e-mail like gmail,yahoo,hotmail etc.. they are all uing https when we comes to login area.. why there are using on that time only https...i also need to implement same in my web application...
is it possible to preserve authentication for ASP.NET Forms authentication cookie,btween Http and Https (different domains) and back?I mean haveing single signon for two domains say http://www.mydomain.com and https://members.mydomain.comI've seen on quite asp.net sites that have a 'MyAccount' section they transfer the site to https and then when you have logged into your account successfully and gone back to the majority of the site you move back to http whilst still being logged in.
I set authentication mode to Windows in the web.config and I enable Windows Authentication and disable the Anonymous Authentication in IIS 7 on win 7, but HttpContext.Current.User is always null.It works fine when I host the web app in IIS 6.0.
I have been trying to avoid the windows login userid and password window when I use the Windows Authentication mode for a web site. I need to capture the the windows logon user name without prompting for the user id and password and display that on the web site. I had tried almost everything... changed authentication,security setups on IE and IIS etc... still not being able to avoid the window...
We have a working version of application (Intranet) with uses Windows Authentication deployed in Windows 2003. The application uses HttpContext.Current.User.Identity.Name to get the logged-in user. Here impersonate is turned off.Right now, we are move to Windows 2008 RC2 where this Windows Authentication problem arised. I have Digest Authentication and Windows Authentication enabled. And also I have enabled Anonymous Authentication enabled to avoid the Login dialog of IIS in the end-user IE. Now I am getting HttpContext.Current.User.Identity.Name as Empty. When I impersonate using username and password, I am used to login using that user but all the users uses the same user to login.Does any has solution for this?Deployment Server - Windows 2008 RC2 (IIS 7.5)Development - Windows 7 (IIS 7.5)I am new to IIS 7.5. Please give me a solution
I have to invoke SSIS packages from web service in the most secure way. I think that windows authentication will be secure but i am not sure. I do not have much knowledge about how to achieve this and the information on the internet is very distributed.
We use Sharepoint to control our websites. We build the sites, then load them into the sharepoint server. My question is if I use windows authentication, how can I get my role security in my web config file to coencide with the asp.net controls that use the Forms authentication. Is there a differenence? Our security uses a session variable for security but there is no where to set up their permissions except in active directory. I hope this makes sense because I would like to implement the LoginView with Role groups but how can I give them the role="administrator"? Do I have to go into active directory and give them these permissions(would take awhile due to the size of the company)? Or do I have to set up priveladges in the web.config file for each user(difficult I think)?
I'm writing a simple Intranet application using windows authentication. I want to restrict access to Safe/UCantSeeMe.aspx. I am aware of the AuthorizeAttribute, but this only works on methods. I also found a good post on doing this with the MVC pattern, but I'm not using MVC. This can be done with roles in forms based security. I read on MSDN that using windows based security means roles are based on groups, but it doesn't go into any detail. how can I restrict access to Safe/UCantSeeMe.aspx?
I have an asp.net web service which has SSL enabled via IIS. It works fine if the user uses https, however I have a user that insists on using http on the url.
What I'd like to do is have the web service (asmx) do the equivalent of the response.redirect to change http to https automatically.
I don't believe that I can do this from a web service so does anyone know a of a similar solution for web services.
I have a login form on the home page of an ASP.NET 3.5 website which for performance reasons needs to be accessed with a standard HTTP connection. Since the normal postback for an ASP.NET page is relative call for the post, it would mean that when the browser posts the values are sent unprotected.
I would like to do one of two things to make this secure:
Force the Postback to be secure to the same page Send the post to a different page using an HTTPS connection
Is there a way to implement option one?
I'm also looking at the Authentication Service, but looking at the URL reference it is using a relative path:
I am trying to get the windows authentication for intranet design Codes return userid of my system but when I try the same fron other system, there too they return only my system's Id.
I want to know if this kind of authentication is possible.
We have an Active Directory account and that account we are using to log in to windows. I have a simple system that needs authentication using the IIS log in box (i dont know what do you call this but what I know is it only comes out when Anonymous user is unchecked in the IIS configuration.) Now, I want this box to appear before my page and the user will be authenticated and be compare to the user who logged in to the windows. If the user who have been authenticated is the same as the user who logged in to the windwos then we will let him in if not he must be denied in accessing the page.
The first problem I have in my mind is how to code it in asp.net to make an authentication when he will try to access my page.
Second is, let us say we have succeeded to show the authentication box, how can I get the username from the log in box and compare it to the user who logged on in windows. Of course we can get the user id of the logged in user from the windows using User.Identity.Name but how about the username from the log in box.
Note: I will not use log in forms even using https. Just the log in provided by the IIS according to the configuration.
What I want to do is, if userA access the website, then the website will use userA's token to access the SQL server. Site is an intranet site.In web.config,I have
IIS:Annoymous login is disabled, Windows authenication is enabled.
SQL server:userA is added as a user to the database.
IIS and SQL server are on different server. Running as userA on another computer, I try to access the website. The website log told me the website was trying to login to the SQL server with NT AuthorityAnnoymous despite I specified to use integrated security and Annoymous login is disabled in IIS.
I have an application that ran fine on a Win 2003 box using windows authentication. After installing the app on a 32-bit Windows Server 2008 box the users are now prompted for domain credentials every time they call the site. I went into IIS manager for IIS7 and disabled anonymous authentication and enabled windows authentication. What do I need to do here for the user to not be prompted for the credentials?
I am developing one portal in asp.net. Im using windows authentication. In our domain, we are give 6 digit number as username. Based on the 6 digit number windows will display the user name. Can I got the user name from asp.net? Im using asp.net with C#.
When I trying with,
WindowsIdentity.GetCurrent().Name - it will return "DomainName123456". Instead of this 6digit number I need the user name. The user name is displaying in start menu.
What's happening is when windows authentication/authorization fails the user get's a login prompt in IE6, IE7 and FireFox. Only when user clicks Cancel button in login prompt they are getting to 401 error page. What I am trying to achieve is to automatically redirect the user to a custom error page when getting 401 error instead of getting login prompt. Is this possible to suppress the login prompt in this scenario or is it this way by design?Here is my setup:I have windows integrated authentication configured in asp.net 2.0 web app.
[Code]....
In IIS I have website Directory Security configured to use Integrated Windows Authentication and disabled Anonymous Authentication
