I'm building an Intranet application based on Ext JS and webservices. Users are authorized using Integrated Windows Authentication, which works fine in IE.
Because my application is in JavaScript, it is loaded in Firefox, but then when I request some data from server I get 'access denied' in Firebug, because all webservices are checking user rights.
Can I request the user to enter his username and password (like login to FTP or a simple login page) in all browsers that don't support Integrated Windows Authentication?
I know there are plugins for Firefox, but I would like a secure solution that don't require plugins.
Windows Authentication is performed via NTLM. If a browser doesn't automatically supply the credentials then a username/password dialog should be shown in all browsers which would prompt the user to enter their credentials. This should happen automatically.
If you can edit the config settings in FireFox then you can make the credentials be submitted automatically by adding the domain to network.automatic-ntlm-auth.trusted-uris in about:config.

I've an asp.net webforms application running on our intranet (same Active Directory).
I want to auto authenticate .
So i'm using on my C# code :
HttpContext.Current.Request.LogonUserIdentity.Name
to get user name and doing some stuff.
In my web.config i'm not specifying any authentication mode.
In IIS 10.0 in default website and also in virtual directory i've
The problem is that from my development PC it works well, but from any other pc's of my organization, Windows keep continue to ask for user and password.
What can it be ?
Thanks
As far as I know, the reason why you achieve the auto authenticate for your web application is the IE security setting.
If your customer doesn't enable this setting, the IE browser will not auto send the username and password to the server to login in the user. So you will face your customer need to type in the username and password.
To solve this issue, you should suggest client side to enable the security setting to auto login in.
More details about how to enable the auto log in you could refer to below steps:
1.Open the IE and find the internet options.
2.Modify the user authentication
When i try to access an ASP.NET MVC web application hosted in IIS 6.0, i'm getting a windows popup that wants me to enter my windows login name and password. After entering the credentials, i can then reach the login page.
See in the below screenshot what fiddler captures when the windows login prompt pops up. What setting do i need in order to avoid this windows prompt?
Two options.
1) Disable Windows authentication. Enable Anonymous or Forms.
2) Edit your IE settings. Add the site into trusted sites and go to custom level, simply scroll to the bottom and "login with current username and password" button ticked. This will auto negotiate the windows login you are using into IIS as a pass thru.
I have configured my ASP.NET website to use windows auth (and disabled annon auth), and setup some authorization rules. The website is deployed on the Intranet and all users have a windows identity.
When a user navigates to the website, the typical "Windows Security" window pops up, asking the user for his identity. I want to disable this, since the user is already logged in with a domain account. The browser should submit the current identity and IIS can use this to auth.
Any ideas?
Note: I am using IE and the Enable Integrated Windows Authentication is checked
In which browser is this happening? Internet Explorer has an option that explicitly defines whether the browser tries to authenticate users automatically.
You can find it in Tools - Internet Options - Advanced - Enable Integrated Windows Authentication.
Where I've seen this symptom happening before, I've had to add the URL the website is on explicitly into the Local Intranet zone in IE.
I just uploaded a project to my hosting, is a asp.net mvc project with authentication.
Just when i enter the web internet explorer prompts a credential windows. If I cancel, the web works correctly. The web works correctly also in local using the visual studio server.
More information:
"Allow Anonymous Access" is checked and the "Basic Authentication" too, but the promt is shown with Basic authentication checked or not.
Also I uploaded a very basic mvc application with authentication and the prompt is not showing, so it does'nt seem's to be an IIS configuration problem.
Also the prompt is showing in both Internet Explorer and firefox, but isn't in Chrome.
Do you have any clues?
Thanks!
It sounds like you have set the authentication mode to Windows? Can you check the Web.config file. If you are intent is to use Forms authentication, you should change it accordingly
Most likely is that you need to allow anonymous access in the IIS configuration manager. Even if your web.config specifies Forms Authentication (or Authentication is set to "None") if IIS is set to disallow anonymous access, then users will be prompted by IIS before the ASP.Net authentication mechanism kicks in.
Edit
I see this behavior if the "Allow Anonymous Access" is checked and the "Windows Authentication" is also checked.
This is all under the "Directory Security" task in the properties for your web site in the IIS manager.
See info below about IIS:
IIS Authentication
Anonymous
Anonymous authentication gives users access to the public areas of your Web site without prompting them for a user name or password....
Basic(uncheck this)
IIS implements Basic authentication, which is part of the HTTP 1.0 specification, using Windows user accounts. When using Basic authentication, the browser prompts the user for a user name and password. This information is then transmitted across HTTP where it is encoded using Base64 encoding. Although most Web servers, proxy servers, and Web browsers support Basic authentication, it is inherently insecure. Because it is easy to decode Base64 encoded data, Basic authentication is essentially sending the password as plain text.

For this to work only anonymous access should be checked in IIS. Otherwise the browser will try to authenticate if possible.
If you are serving "static content" with your site, the default webroot from which the application is configured under needs these settings as well. (Usually "Anonymous" as only-checked-box).
If my ASP.NET app is set up for ADFS using Windows Integrated Authentication, I know this will work in IE, but will it work in Firefox?
I've seen some things on the web that indicate that there are problems, and you need to put a workaround in each client browser - http://codebetter.com/blogs/eric.wise/archive/2006/11/16/Note-to-self_3A00_-Firefox-Windows-Authentication.aspx
It's not a workaround. Firefox will not send your Windows Integrated Credentials to a website by default. You have to tell it to "trust" the website.
You could display those instructions on a page you direct unauthenticated users to.
