Windows Authentication on an intranet website


I am deploying a website on IIS 7 that requires windows authentication (this is to be used on an intranet only). We would like the authentication to occur using the logged in user's Windows login without the user's input, i.e. when the user navigates to the site, we want to be able to authenticate against Active Directory to check if the logged in user is in a particluar group, but we don't want the pop-up asking for the username and password to appear.

I have most of it working, I just can't find a way to supress the windows authentication pop-up.

Is this even possible?

In IIS 7 I have set Windows Authentication to enabled, is there anything else I need to do?

In my Web.config I have:

<authentication mode="Windows" />

In my class I have:

If User.IsInRole("DOMAIN\GroupName") Then
            Response.Write(User.Identity.Name.ToString & " Is in role")
            Response.Write(User.Identity.Name.ToString & " Is NOT in role")
 End If

Open in new window

Any help is greatly appreciated!

have you configured authentication on iis7 server? (open Internet information service from administrative tools on servere - or via mmc, point to web site and then in the right panle search for IIS->authentication)

Hi Cimperiali

Thanks for your comment. I have enabled the windows authentication in IIS 7. How can I stop the windows login pop-up when a user makes a request to the website?

What I want to achieve is that a user should be able to jump straight to the website without having to input their windows login details.  

The asp.net server side code "User.IsInRole("DOMAIN\GroupName")" should check the requesting user's windows login. If they belong to a defined AD group they will be granted access to the website, otherwise the user will be redirected to a "Access Denied" page.

are you using ie ? Look for athomatic logon  property in Advanced Internet options
for firefox, instead, try follow this tip:
