Security :: User.Identity.IsAuthenticated Returns True But Session Has Expired
May 24, 2010
I have a page where, when the user has successfully logged in, I store some values in the session.
I then use these values to load an application list page. This page is automatically refreshed after 20.1 minutes, with the sessionstate timeout and forms timeout in web.config set to 20 minutes (with sliding expiration). This means, if the user does not use any page for more than 20 minutes, he is timed out.
My problem is that the User.Identity.IsAuthenticated sometimes returns true, when the session has expired.
Why is this happening, and how can I fix it?

I create two pages, the first one is the login page with user name and password textboxes - (not asp login control) , when clicking login button I check the login authentication, if it is true redirect to default page. in the default page if !IsCallBack then i check httpcontext.current.user.identity.isauthenticated
if it is false i redirect the user to the login page. but my problem is that the httpcontext.current.user.identity.isauthenticated is always false.
Below the section of authentication in web config

We have an SharePoint site no login (anonymous) with a search module using AJAX. Now the users complains that the module isn't working. When I check the code (not developed by me), I find that the code only runs if "HttpContext.Current.User.Identity.IsAuthenticated=true". Could that ever return true on an anonymous site?

I need an app pool recycle to be completely transparent to the users of my web app. I use ASP.NET 3.5 MVC 1.
Currently, upon an IIS 7 App Pool recycle all users logged into my web app are kicked out and are required to log back in (Context.User.Identity.IsAuthenticated is set to false). I employ SQL State Server, I use forms authentication and both are configured to use cookies. I was under the impression that .NET and/or IIS handles authentication of cookies.
However, every time the app pool is recycled Context.User.Identity.IsAuthenticated is set to false my users are kicked out and are required to log back in. I can see that the session id remains the same throughout logins, I can also view this session information in the database/state server.
Logon method:

when ever i check User.Identity.AuthenticationType the returned string is 'Custom' always, doesn't matter my authentication type is 'Windows' or '''Forms'.
I want to do some different coding in aspx.cs for windows and forms authentication, but i am unable to differentiate between them because 'User.Identity.AuthenticationType' always returns 'Custom'.

I am trying to create a httphandler which will intercept a sample pdf file which we have in our website. The httphandler works fine from within my development machine and even my locally published website that if I just try to connect to the test url: [URL] I will get sent to the invalid access page. So pushing it to our IIS6 machine when I try to go to the URL it serves up the PDF document. context.User.Identity.IsAuthenticated is always showing as true. I'm using forms authentication. below is the code I am using as the handler.
public void ProcessRequest(HttpContext context)
{
if (context.User.Identity.IsAuthenticated)
{
string SampleURL = context.Request.AppRelativeCurrentExecutionFilePath;
context.Response.Buffer = true;
context.Response.Clear();
using (FileStream fs = new FileStream(HttpContext.Current.Server.MapPath(SampleURL),FileMode.Open))
{
int length = (int)fs.Length;
byte[] buffer;
using (BinaryReader br = new BinaryReader(fs))
{
buffer = br.ReadBytes(length);
}
context.Response.Clear();
context.Response.Buffer = true;
context.Response.ContentType = "application/pdf";
context.Response.BinaryWrite(buffer);
context.Response.End();
}
}
else
{
context.Response.Redirect(
"~/Error/invalid_access.aspx");
}}
in web.config I have the following for form authentication:
<authentication mode="Forms">
<forms name="Sample.Web" loginUrl="~/Security/" defaultUrl="~/default.aspx" protection="All" timeout="60" path="/" requireSSL="false" slidingExpiration="true" enableCrossAppRedirects="false" cookieless="UseDeviceProfile" domain="">
</forms>
</authentication>
<authorization>
<deny users="?"/>
</authorization>

I am using forms authentication and have an issue with a particular browser using the remember me feature. For various reasons I want to support the opera browser that works with the nintendo dsi. I can use forms authentication with that browser just fine but when I use the remember me (cookie) feature I can get through the login but then calls to User.Identity.IsAuthenticated return false. If I do not check remember me it works fine. Initially I thought the browser didn't support cookies but it does. At least I can go to m.gmail.com and check their version of remember me and it works. I can exit the browser and come back in and m.gmail.com remembers me. Also I don't have problems with remember me on any other browser I have tried.
Is anyone aware of some specific browser issue that doesn't work with asp.net forms authentication? I am using asp.net mvc but I doubt that matters.

What is the best sequence order for Page.IsPostBack and User.Identity.IsAuthenticated? From what I have search for, this comes up most common:
If Not Page.IsPostBack Then
If User.Identity.IsAuthenticated Then
~Some kind of code~
End If
End If
Is this considered "best practice" or can the two items - Page.IsPostBack and User.Identity.IsAuthenticated -be split into their own sections so the fuctions of these can be independent of each other?I am trying to troubleshoot a placeholder that disappears from a master page when a content page button is pressed to change the content pages active view (I have a multiview w/ 5 views inside of it).

I am using Form Authentication and sending an Aajx request to the server for authentication. Based on the json result, the client decides where to go and what to do. That is the reason I am not using FormsAuthentication.RedirectFromLoginPage to not interfere the ajax/json response.In this case Request.IsAuthenticated returns false, even after validating the user with Membership.ValidateUser. Then I set the cookie using FormsAuthentication.SetAuthCookie(username, false)

I have identity impersonate = true in the Web.config file. I have integrated security = true in the DB connection string in the Web.config file.Before identity impersonate was true,users were able to access the DB through the web service account (seemingly).Now I get an error which says " Login failed for ... " because I am aware there is no specific account for that user in the permissions for that DB instance.I needed to set identity impersonate = true because the web service does not have access to the Active Directory,which I need to retrieve certain user information.
My question is,does identity impersonate = true override the integrated security and attempt to user the authenticated user's account to connect to the DB? Is there a simple way to prevent this in the Web.config itself?If not,would programatically impersonating the user within the Active Directory query functions and setting identity impersonate = false do the trick here?

I have implemented Forms authentication in an ASP.NET MVC 2 website
By using <%: Page.User.Identity.Name %> on the Site.Master page I can display the userid of the logged in user.
I would like to use this value and display other information about the user that is stored in a User table in a MsSQL database, like:
<%: GetFirstname(Page.User.Identity.Name) %>

I have an Intranet web site that uses Windows Authentication and when a users password expires the do not get a prompt letting them reset it. We also have OWA and if they go there to check mail, it sends them to a page which allows them to reset it there. How can I trap for expired passwords and allow them to change it like they can with OWA?

Is there a simple way to just retrieve the user's name, and not the Domain name, when using this function:
string quizTaker = Page.User.Identity.Name.ToString();
Right now it returns "DOMAIN_NAMEUserName"
I would like to just use isolate and use the user's name, without the Domain name.

I have an aspx page that has all its controls inside the scriptmanager and update panel.
I want to send the user to sessionexpired page after 20 mins of inactivity.
For this, I am writing the below code on page_load
Response.AppendHeader(
"Refresh", Convert.ToString((Session.Timeout * 60) + 10) &
"; URL=SessionExpired.aspx")
But the page is going to sessionexpired page after 20 mins even if the user is working on the page.
I think since I have all my controls in an update panel it is not doing a complete postback and hence the session object is not getting refreshed.

In the website we have several folders, some folders are accessible by anonymous users, others are accessible by members only, some by administrators or a both administrators and members can view this folder. Each folder contains some forms; these forms are based on the role as well. We'd like to add "user.identity" as to authenticate the user based on the user_id from table websit_ users.
However we are not sure , wither we need to specify each and every form, folder or this will be done automatically once authentication is applied. And where do we put the user.identity and what is the exact format of it. Do we include it in our Global.asax after the authentication part?! This is the code in global.asax:

I'm in the middle of moving a web application from IIS6 to IIS7. I've enabled "Windows Authentication" and added <deny users="?" /> to the authorization section of my web.config file. When the app was running on IIS6 my users where able to access the web app without logging in because their windows login was automatically recognized. This does not seem to be the case in II7. I can not get a value for "Current.User.Identity.Name" in my ASP.Net code.
