I have a bug in which, whenever an error occurs the user seems to get logged out. After much research I find that the situation is not so simple:
(note I have dumbed these down a bit to make it easier to follow)
Web.config - I turn on Custom Error Mode
i'm using ASP.NET membership for a silverlight application that makes use of Wcf Ria Services.
my problem is that i don't want multiple logins on the same account and i need to logout the user when he logs in on another machine. (I don't want the account to be used by many people at the same time, and the last who logs in must kick out everyone else)
Need the code for the login /logout in my sample project and how to attin logout in the all pages. dont mistake me as i am learning (fresher) the asp.net 2005
View 2 RepliesI have set the destinationpageurl of my login control to login.aspx. On successfully logging in to my website, I get redirected to the directory listing. Why is this? What am I doing wrong?
Also, what do I need to do to not allow the user to see the directory listing ever.
on page refresh it redirects to login page. why?
View 1 RepliesI want to log out the user when he (or someone else) logs in from a diferent computer using the same user name.
Basicaly i want to prevent multiple individuals from staying loged in under a single user name by signing out the previous users. Any ideeas about how i can acomplish that ?
I need to show the user a different page when he loggs in for first time alone..
How can i do this..
i am using membership to create an account page that a user enters after logging on.
In the page load of "MyAccountPage.aspx" I have the following which gets the userid and add it as a paremeter
Guid userid = (Guid)Membership.GetUser().ProviderUserKey;"ClientId"].DefaultValue
= userid.ToString();
ObjectDataSource7.SelectParameters[
"ClientId"].DefaultValue = userid.ToString();
This works fine - I have now added to the page a LoginStatus as when they arrive they are loggen in. The problem is when the user clicks the Logg off link I get the error on the page below -
Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:
[Code]....
Is this because the page load is trying to get the logged on user ID
but they have just logged out?
How can I allow the User to logg out without getting the error?
I am working on an application to read event logs on a remote machine. I tried adding this to the web.config
<identity impersonate="true" user="domainuser" password="password" />
However, when I ran this, I got the following error:
Could not create Windows user token from the credentials specified in the config file. Error from the operating system 'Logon failure: unknown user name or bad password.
I looked at this post

It seemed to suggest I would need to create a new account on the remote server. Is there a way I can just use an existing domain account?
I've been trying to work out this error for a while now and i still dont understand it because i have been following a tutorial online step-by-step but i recieve this error when i log in ?
What i am trying to acheive is when the user logs in then they are able to view their 'profile' such as their name, address etc. The login is validated against a table in a database, ...this is the error i am recieving:
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

I'm trying to set up the SSL in my web app, but don't know if i'm doing it right, or if even i'm taking the right steps in the right order.I have a function in a class that returns the secure URL (https://mydomain.com/...aspx) if the current url is not secure (http)
[Code]....
(Though in develop environment It's like "https://localhost:port" + rawUrl)
when the function returns ssl value, if it's not empty, then the master page redirects to the new url... but the browser is not showing it...
I need to display a javascript confirm box after the user successfully logs into the application. If the select 'yes' of the confirm box then I need to navigate them to a different page and if they select 'no' the default.aspx page should be displayed. I am using the login control.
I tried to use ClientScript. RegisterClientScriptBlock on Login1_Authenticate event, it didn't work. I tried the same thing on the Page_Load event of Default.aspx as well as Master Page load event, that also didnt work.
i use formsauthentication for login. but i wanna register user logs logs table. i can access username page.user.identity.name, but how can use userid?
View 4 RepliesI am using following setting for customError.
< customErrors mode="On" defaultRedirect="GenericErrorPage.aspx" >
< error statusCode="403" redirect="NoAccess.aspx" />
< error statusCode="404" redirect="FileNotFound.aspx" />
< /customErrors>
I have a folder "Admin" having access to administrators role. When someone other than administrators tries to access the pages inside admin folder, it is redirected to login page. My expectation is to display "NoAccess.aspx". Whats wrong with this code? Or is there other meaning to statusCode=403.
Using VB.Net 3.5 framework, i have a site that is using a custom login form and custom error with custom error page in global.asax and web.config is set up for both the login form and custom error. All works fine: my users login and when they get an error, they get the custom error page. The pages also use querystrings when moving about the site in order to retrieve data from a data base using a customer name (this is not the login name) and order number. When an error occurs anywhere in the site, I'd like to pass the page name and its querystring parameters
(ex: page1.aspx?a=1&b=2) to the custom error as well as the user information so that all the user sees is the custom error page telling them the error and all details were sent to the admin. Currently, the custom error page has an email link so the user can send a message that includes the details which results in 2 emails being generated for an error: one from global.asax with the error info/stack trace and the one the user sends with the details.
In my mind, a graceful failure does not require input from the user, just an apology and assurance the problem has been fully reported and will be taken care of. So, can someone assist in getting the current user and page/querystring into the custom error code in global.asax?
Since I start hating postbacks, I use WS or PageMethod for every client to server process. I did same for Logout but Im not sure in this.
I wrote code like this
//In WS
[Code]....
//on aspx
[Code]....
everything working fine, but I have some kind of feeling that I'm missing something(like calling any other method) ? I just wanna make sure as its for security purpose.
I have a login page and a default page to be redirected to after login. when I clicked on thew logout button in the default page it correctly redirects to login page. But when I click the back button in the IE I can again see the protected default page( in mozilla everythng is OK, no problem but in IE this problem occurs).
Have I done something wrong. My code r below:
login page===========
protected void Login1_LoggedIn(object sender, EventArgs e)
{
if (Roles.IsUserInRole(Login1.UserName, "Members")) {
Response.Redirect("users/Member/default.aspx");
//Server.Transfer("users/Member/default.aspx",true);
}
}
===========
default page has a LoginStatus button( logout action: RedirectToLoginPage)
give me a working snippet for logout..I'm fed up of using all session.abondon() bla bla.. Even after logout wen i click back button i can view my page.. How to over come this..
View 14 RepliesI redirect Errors to Error.aspx
<system.web>
<customErrors defaultRedirect="error.aspx" mode="On">
error redirect="error.aspx" statusCode="500" />
</system.web>
and the problem is that there is also second error in ErrorMasterPage of Error.aspx
<script Language="C#" MasterPageFile="~/ErrorMaster.Master" runat="Server">
and CustomError can not handle the second error while its like a loop ( it will redirect to error.aspx and Masterpage of Error.aspx has Error.
Example:
Login.aspx(has Error) -> Error.aspx -> ErrorMasterPage.Master (has Error) -> Show Yellow Page
i designed 3 pages...
1. login
2. mailbox..
3. that is redirected after logout.
i used sessions here...and session.Abondon() for logout.. bt if we go back from the browser button provided top-left corner, then mailbox is opened again...without even logging in..... its dangerous.
I got a problem with my login and logout for my asp.net website, whenever i try to login or logout, it will load the page i direct it to first then i have to reload the page again for the login or logout to work. First my login i am using a login control to do it and also using this code to go to another page:
protected void Login1_LoggedIn(object sender, EventArgs e)
{
Server.Transfer("LogonPage.aspx");
}
Next is my logout i am just using a button for the logout along with this codes:
protected void btnLogout_Click(object sender, EventArgs e)
{
Response.Clear();
FormsAuthentication.SignOut();
Server.Transfer("Login.aspx");
}
i really want it to login and logout at my first click.
<asp:LoginStatus ID="HeadLoginStatus" runat="server" LogoutAction="Redirect" LogoutText="Log out"
LogoutPageUrl="~/" />
to MVC musicstore sample in .NET 3.5. Clicking in "Log out" hyperlink calls javascript postback function. Current page is re-dispalyed (master page is not shown) and Log out message is still displayed. Log in link does not appear How to fix this so that log out really logs out ?
[Code]....
In the site I am building we have standard users and superusers. A superuser can delete another user from the system and this should result in that user being logged out (if he/she is currently logged in). We use the Membership provider. Or actually the superuser doesnīt delete the other user completely but instead sets his/her as inActive by following code:
[code]...
But, that should not matter... What I want to know is how to make the affected user being logged out. I donīt need a popup or anything to be shown to the other user that he/she is just logged out, it is enough to check if that user is logged in when he/she tries to move to another page on my site.
When closing my tab, Formsauthentication doesn't clear.

the web application was designed using asp.net 4.0/C# with form authentication .
logout is not working. After deleting web history, cookies, passwords, then also logout is not working.
