Is this a security issue or by design?string UID = "randomusername" // does not exists in aspnet_Users table
FormsAuthentication.RedirectFromLoginPage(UID, false);Authenticates users, redirects to login page.Profile Page is set to chech User.Identity.IsAuthenticated etc...when they update the profile, it ads the user to the aspnet_users table automatically, which is not what I want.
What is the difference between:
FormsAuthentication.RedirectFromLoginPage
AND
FormsAuthentication.SetAuthCookie(Text_txtUserName.Text, true);
HttpContext.Current.Response.Redirect(RedirectFromLoginAddress);
I have a dropdownlist for which I am loading data from excel. Excel has 2 columns Product and Email. Data in Product column is binding to DataTextField and Email column to DataValueField. The dropdown works fine when email is different for different product but when email has same value for different product then whatever I select, on postback the selected value changes to the first item of the same email value.
Below are the sample data in Excel to show the behavior of dropdown
Example 1. (Drop down works fine for this example)
Product Email
iPad prashanth364@gmail.com
iPhone 3G prashanth364@yahoo.co.in
iPhone4 prashanth364@in.com
Example 2. (In the example below, whatever I select (iPad or iPhone 3G or iPhone4) on post back the dropdown selected value will be iPad)
Product Email
iPad prashanth364@gmail.com
iPhone 3G prashanth364@gmail.com
iPhone4 prashanth364@gmail.com
Example 3. (In the example below, when I select iPad the dropdown works fine but when I select iPhone 3G or iPhone4 on post back the dropdown selected value will be iPhone 3G. Basically, on selecting iPhone4 here, on post back it shows iPhone 3G)
Product Email
iPad prashanth364@yahoo.co.in
iPhone 3G prashanth364@gmail.com
iPhone4 prashanth364@gmail.com
Below is the function where I am loaidng the data from excel to dropdown private void ExtractFromExcelInitial()
{
// Put user code to initialize the page here
// Create connection string variable. Modify the "Data Source"
// parameter as appropriate for your environment.
string ExcelFilePath = Server.MapPath("~/ProductExcel") + "\ProductEmail.xls";
String sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + ExcelFilePath + ";" +
"Extended Properties=Excel 8.0;";

I am trying to match an email, however when put the same expression in the code behind, vs the aspx, I seem to be getting different matches for email address. The aspx regex validator seems to be working correctly, however I need to validate for my webservice as well.
Regex regExEmail = new Regex(@"w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*");
if (!regExEmail.IsMatch(contact.emailAddress))
{
//do something
}
I have an .aspx page that contains an <asp:Login> web control. For authentication, I have another class (MyMembershipProvider) that inherits System.Web.Security.MembershipProvider class.The login process is working fine - i.e. username/password is properly authenticated by the MyMembershipProvider object.
My question is in regards to setting System.Web.SessionState.HttpSessionState.Session variables.After a user has been successfully authenticated (by the MyMembershipProvider class), I would like to create custom Session vars for that user.Initially, I thought I would be able to set the Session variables in the <asp:Login> control's LoggedIn event handler - something like this:
protected void LoginUser_LoggedIn(object sender, EventArgs e)
{
//Get the UserName of the authenticated user
string userName = Thread.CurrentPrincipal.Identity.Name;[code].....
I'm puzzled by the behaviour of two hyperlinks in my Master Page which appear to be identical. The link to ~/Default.aspx in the href in line 5 of the code below causes a 404 error, but the same link in NavigateUrl on line 9 works fine. On the face of it they should both go to the same page. What's different/incorrect about the link on line 5 that causes the problem?

I am absoluetly confused. My web app has a checkbox list that my code is looking to see if the user checked it. Like I said, very simple stuff... Here's the code:
If (chkLaunch.Items(1).Selected) Then
Launch = 1
End If
The odd thing is that when it gets to this bit of code it just moves right past it like it wasn't checked. The same thing happens when I use a single checkbox (rather than a checkbox list). I've tried a bunch of different ways to make the code work but I'm left to the conclusion that I'm just not telling it to do this correctly. Either that or my project is messed up somehow.I say that my project is messed up because when I add an object to the page in Design mode, it doesn't write the source code. So when I save and close, all the modifications are mysteriously gone. This happens on multiple PC's...So, is the checkbox problem just me not doing something correctly or is my web project messed up?

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.
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,
In my account controller I am calling FormsAuthentication.SetAuthCookie( emailAddress, rememberMe ).
Response.Cookies has my cookie. However, after the redirect the cookie is gone and the request is not authenticated.
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)

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?
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.
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.
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.
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="*"/>
</authorization>
</system.web>
</location>
I'm using asp.net (c#) with iis 7.0.
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.
