How i can implement Windows Authentication to authenticate user while logging in? I do not want to get a pop up window rather i would like to let my login page(LoginPage.aspx) do the same. Please provide me with the steps/ code(vb.net). Thanks
It requires a good amount of code to access active directory and authenticate.Please refer the article on codeproject.com or msdn articles.
Maybe you could use this tag in your web.config
<authentication mode="Forms">
<forms loginUrl="login.aspx" defaultUrl="Login.aspx" timeout="60"></forms>
</authentication>
And in your login.aspx you would write code to access Active Directory.
You are missing the point about what windows authentication is. Forms authentication can be used when not part of a domain or there is some specific requirement that windows authentication cannot solve. If a computer is registered in an active directory domain, authentication with the web site will be transparent based on the credentials that were used to login to the domain, eliminating the need to supply credentials each time the application is accessed.

I had form authentication on my website.
It was on a web farm server and I had a directory on my website to write some log files.
I used password protection on the pleask to protect my directory and it worked fine.
When user want to see contents of that directory, they must have entered a username and password.
Last week I moved my site to a dedicated server and now I want to enable that feature again.
in iis7>mysite>mydirectory>authentication
but I cannot disable form authentication why?
I removed
<authentication mode="Forms">
<forms domain=".mysite.com" loginUrl="Login" timeout="50"
requireSSL="false" path="/" />
In web.config I can disable authentication feature in iis and enable basic authentication and everything work good.
But now how can I handle it without removing my codes?
How did it worked when I was on plesk hosting panel?
I want users to enter a username and password to view a file on my folder.
I found an article that shows how you Enable Forms Authentication (IIS 7)

I am working on several asp.net sites simultaniously. All of them use cookie-based (out of the box) authentication mechnism. When a web site on localhost:4587 was being bedduged in VS I have logged in as an "admin" user and did some testing.
The next day I am opening different project for debugging that runs on localhost. And when I attempt to access the MVC controller action that is marked with Authorization atribute, the system assumes the current user is "admin" and is looking for it's roles based on a custom provider. But on this site, there isn't even a user named "admin". How can I make sure cookies from other sites don't make it to Role check in ASP.NET MVC application?
I would suggest it is always a good practice to delete all localhost cookies after testing. As explained here : asp.net cookies, authentication and session timeouts , you can also add details to the authentication cookie to ensure it is discarded after a session, ie when you close the browser or to differentiate between two sites. Another approach to avoid cookies 'clashing' is to use two different browsers : Chrome for the one and a Comodo Dragon or Chromium for the other.
Give your forms tag a unique name in each application
<authentication mode="Forms">
<forms name="myVeryUniqueNameForApp1" />
</authentication>
<authentication mode="Forms">
<forms name="myCompletelyUniqueNameForApp2" />
</authentication>
We have developed implemented single sign on methodology to authenticate user.
When a page is requested, if it is not authenticated then a login page will be redirected. Once they logged in the requested page will be shown.
this is working when we don't assign a domain to the virtual directory. But when we assign the domain to virtual directory after the authentication the application is not redirecting to the requested page.
We are using FormsAuthentication.GetRedirectUrl method to redirect the requested page.
Why this is happening? How can we resolve this issue?
You might want to check Windows Identity Framework too.
Good article here : Windows Identity Foundation features for passive single sign-on and single sign-out
First add defaulturl to your web.config and see if page can redirect to defaulturl after authentication
<authentication mode="Forms">
<forms loginUrl = "login.aspx" defaultUrl="default.aspx" />
</authentication>
If defaulturl works then you have to check ReturnUrl parameter in your login page address
If you have a web application that will run inside a network, it makes sense for it to support windows authentication (active directory?).
Would it make sense to use AD security model as well, or would I make my own roles/security module that some admin would have to configure for each user?
I've never dealt with windows security before, so I am very confused as to how I should be handling security for a web application that runs within a windows network.
I guess there are 2 major points I have to tackle:
1. authentication
2. authorization
I have a feeling that best-practice would say to handle authorization myself, but use AD authentication right?
Basically windows handles everything, you never store usernames or passwords, AD and IIS do all the work for you
add this to your web.config
<system.web>
...
<authentication mode="Windows"/>
...
</system.web>
To configure Windows authentication
Start Internet Information Services
(IIS).
Right-click your
application's virtual directory, and
then click Properties.
Click the
Directory Security tab.
Under
Anonymous access and authentication
control, click Edit.
Make sure the
Anonymous access check box is not
selected and that Integrated Windows
authentication is the only selected
check box.
You can then deal with the business or authorization using web.config again. for example
<authorization>
<deny users="DomainName\UserName" />
<allow roles="DomainName\WindowsGroup" />
</authorization>

I used windows security on some of my internal sites.
Basically the way I set it up is I remove anonymous access in IIS, then assign permissions on the sites files though the standard windows security model.
I'm not sure if this is the best practices, but it has always worked well for me.
I'm working on a website built with pure HTML and CSS, and I need a way to restrict access to pages located within particular directories within the site. The solution I came up with was, of course, ASP.NET Forms Authorization. I created the default Visual Studio log in form and set up the users, roles, and access restrictions with Visual Studio's wizard. The problem is, I can't log in to the website with the credentials that I have set.
I'm using IIS 7.
I'd guess (since I don't have IIS7 handy ATM) that you'd need to turn off Anonomyous Auth, and enable Forms Auth in the IIS7 sections.
At what point did you insert your login/password? Did you have a look at the tables that where created? Althought your password must be encrypted, maybe it's worth just checking if your user was actually created.

Forms Authentication does not require any form of user database.
Steve, can you please paste in your forms authentication web.config section, also any relevant code to the ASP.NET Login control you were using.
There is not enough information to troubleshoot here yet :)
The web.config section is pretty useless as far as I can tell:
<authentication mode="Forms" />
I looked in IIS 7, and in the Authentication section it says: Anonymous Authentication = Enabled, ASP.NET Impersonation = Disabled, Basic Authentication = Disabled, Forms Authentication = Disabled.
Also, I have made no changes to the code other than dragging a Login object onto the designer and changing the page it points at to index.html.
Currently, the log in fails by displaying the log in failed text.
EDIT: Earlier when I would try to navigate directly to a page that is restricted, I would receive a blue page saying that I had insufficient permissions. Now I can see the pages that are restricted without logging in even though I have anon access denied.
Steve,
I don't think the issue is with your IIS settings. Because forms authentication does not rely on IIS authentication, you should configure anonymous access for your application in IIS if you intend to use forms authentication in your ASP.NET application.
Try this in your web.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<authentication mode="Forms" >
<forms loginUrl="~/login.aspx" defaultUrl="~/">
<credentials passwordFormat="Clear">
<user name="YourUsername" password="superSecret" />
</credentials>
</forms>
</authentication>
<authorization>
<deny users="?"/>
</authorization>
<system.web>
</configuration>
There are better ways to implement forms authentication than hardcoding a username and password into your web.config, but this should work for getting you started.
