Security :: FormsAuthentication LoginUrl Messing With CSS?

MVC Authorize Attribute + HttpUnauthorizedResult + FormsAuthentication

Jan 26, 2010

After browsing the MVC section on CodePlex I noticed that the [Authorize] attribute in MVC returns a HttpUnauthorizedResult() when authorization fails (codeplex AuthorizeAttribute class). In the source of HttpUnauthorizedResult() from CodePlex is the code (I'm not allowed to enter another URL as my rep isn't high enough, but replace the numbers on the URL above with 22929#266476):

// 401 is the HTTP status code for unauthorized access - setting this
// will cause the active authentication module to execute its default
// unauthorized handler context.HttpContext.Response.StatusCode = 401;

In particular, the comment describes the authentication module's default unauthorized handler. I can't seem to find any information on this default unauthorized handler. In particular, I'm not using ormsAuthentication and when authorization fails I get an ugly IIS 401 error page. Does anyone know about this default unauthorized handler, and in particular how FormsAuthentication hooks itself in to override it? I'm writing a really simple app for my football team who confirm or deny whether they can play a particular match. If I enable FormsAuthentication in the web.config the redirect works, but I'm not using FormsAuthentication and I'd like to know if there's a workaround.

Security :: Password Encryption Using Formsauthentication?

Dec 1, 2010

Just a quick question i've been asked to look at enhancing security but encrypting passwords we store in a db table, essentially the data thats linked to the user account isnt sensitive however its more to stop someone reading passwords out of the table directly etc

I've read multiple ways of implimenting hashing etc i've started using FormsAuthentication.HashPasswordForStoringInConfigFile
//create new salt and update the password
Hashtable newInfo = new Hashtable();
newInfo["salt"] = GenerateFriendlyPassword(5);
string tmppass = FormsAuthentication.HashPasswordForStoringInConfigFile(txtNewPass1.Text.ToString() + newInfo["salt"].ToString(), "SHA1");
newInfo["passwordHash"] = tmppass;

Generate friendly password returns a 5 char string based on a random position in a valid char array containing a - z and 0 - 9At present the functionality is at page level in the code behind, re this is the forms authentication HashPasswordForStoringInConfigFile function thread safe? Or do i need to look at implimenting this in a different wayCheers appreciate your response as im always jubious about multi threading etc,

FormsAuthentication.RedirectFromLoginPage Does Not Return To Orignal URL?

Jan 5, 2010

I reach my login page with the parameter "returnUrl" set to the URL I was on. Then, I login via OpenID (DotNetOpenAuth), and call FormsAuthentication.RedirectFromLoginPage(). The login is successful, however I am not returned to the original page I was on.

I'm having the same problem on logout - when I log out I don't remain on the same page, even though the logout link contains the correct "returnUrl" parameter.

What am I doing wrong?

Here is the code snippet. I am returning EmptyResult() after the call to RedirectFromLoginPage, because I don't really know what to do (see this related question)

Call FormsAuthentication.RedirectFromLoginPage 10'000 Times?

Dec 30, 2010

Is it OK to call FormsAuthentication.RedirectFromLoginPage many times?

On login page we test if user is already logged in, and if it is we just redirect him to default page with FormsAuthentication.RedirectFromLoginPage...

Question is if user sets a script that loads login page 10'000 times, would calling the FormsAuthentication.RedirectFromLoginPage that many times make problems?

Authorization Denied Message With FormsAuthentication?

Jul 21, 2010

So, I've implemented my IPrincipal.IsInRole(...) and I'm using FormsAuthentication like so:

<authentication mode="Forms">
<forms loginUrl="Login.aspx" name="someName" timeout="600"/>
</authentication>

Then I have a page that requires you to be authenticated and that you have "roleA". This is configured like so:

<location path="SomePage.aspx">
<system.web>
<authorization>[code]...

Now, I login to my web application, but with a user that does NOT have roleA. When I visit SomePage.aspx I get redirected to Login.aspx, the url specified in loginUrl of the forms element. So, my question is shouldn't I be able be specify an authorization denied message or url? If the user is authenticated, but not authorized why would I want to redirect to the login page. It's confusing as hell to the user.

Can't Debug / Step-into FormsAuthentication.Authenticate?

Dec 20, 2010

I am having some trouble with active directory authentication using FormsAuthentication in ASP.NET MVC 2 (VS 2010).

As I understand it I should be able to step into/through the Microsoft source code for FormsAuthentication.Authenticate if I check 'Enable source server support' and 'Enable .Net Framework source stepping' in Options->Debug->General and specify 'Microsoft Symbol Servers' in Options->Debug->Symbols.

I have done this and can step into a whole bunch of MS source code, but not FormsAuthentication.Authenticate. The debugger simple steps over it.

If I could step into FormsAuthentication.Authenticate it would make my life a whole lot easier.

C# - FormsAuthentication AuthCookie Is Null Only For Some Users?

Jan 14, 2010

I am experiencing a strange problem with asp.net forms authentication. This problem only occurs for 3 users out of 30+ users that have successfully logged in. I am using very basic auth code that I have used many times and have never seen this problem. After the users successfully authenticates and the auth cookie is created, cookie added, and response.redirect to FormsAuthentication.GetRedirect(userid, false) is called. The Application_AuthenticateRequest method in Global.asax is hit.

// Extract the forms authentication cookie
tring cookieName = FormsAuthentication.FormsCookieName;
HttpCookie authCookie = Context.Request.Cookies[cookieName];
if (null == authCookie)
{
// There is no authentication cookie.
return;
}

So immediately after a "good" cookie is saved and the redirect occurs the cookie is null. I have run the code through the debugger and the cookie is only null on these 3 users. But the cookie looks the same as the cookie for the many users that login successfully.

Prevent Formsauthentication To Block Css And Images?

Jun 28, 2010

I have a project containing an image, css and js folder. I want to make sure no css, image or js is blocked when using formsauthentication.

I know you can do this with the locationtag in the web.config but I was wondering if you could do this otherweise?

this is how I do it right now:

<location path="css">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
<location path="images">
<system.web>
<authorization>
<allow users="*"/>

</system.web>

FormsAuthentication.GetRedirectUrl Always Returns The Default?

Nov 22, 2010

I have an ASP.NET MVC app and am using Forms auth. When going to a page that requires authentication, meaning there is an [Authorize] attribute on the controller action, it redirects the user to the login page with a return url like http://localhost/Login?ReturnUrl=/MyAuthorizedUrl.

This is how my config is setup:

<authentication mode="Forms">
<forms loginUrl="~/Login" timeout="2880" defaultUrl="~/" />
</authentication>

This is how I'm getting the redirect url:

var url = FormsAuthentication.GetRedirectUrl( model.Email, model.RememberMe );

This always returns the default url.

Calling FormsAuthentication.SignOut(); After Invalidating The Page?

Is it possible to validate a user's Username + Password without logging them in? I understand a usual login block will look like this:

With the Membership.ValidateUser() call setting the cookie for the response.

However, there are some additional checks I'd like to perform after the password is confirmed. (Pulling out an expiry date for that user, for example).

Is there a way to do it without just calling FormsAuthentication.SignOut(); after invalidating the page?

Security - FormsAuthentication - Unable To Redirect After Login?

Aug 9, 2010

I am using Forms Authentication in my VS-2005 website.In case of wrong credentials or while explicitly requesting protected pages the website is able to redirect user to login page. However, when correct login credentials are provided the application is not able to redirect the user to the desired page.While debugging I found that 'Request.IsAuthenticated=False' just before I redirect the user to the desired page.While coding I thought that this property will be set to true automatically after I generate the Authentication ticket. So do I need to set it explicitly inside the submit button click on Login page after validation?BTW I have not used the 'GetAuthcookie', 'SetAuthCookie' or 'RedirectFromLoginPage' methods.
I am posting the code inside the submit button click on the Login page as well as the Authentication and Authorization tags in web.config.

<authentication mode="Forms">
<forms name=".ASPXFORMSDEMO" loginUrl="~/Login.aspx" cookieless="UseCookies" path="~/"/>
</authentication>
<authorization>
<deny users="?"/>
</authorization>
