Security :: To Logout The User When He Logs In On Another Machine?
Sep 8, 2010
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)
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 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 ?
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'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 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.
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.
if a user wants to clear their personal information from a page after clicking on a button that they be re-directed to the ASP Login page. This code needs to be developed using Java Script because I want the user to confirm with a confirmation box that they intended to clear their info. I have found resources on MS that pointed to referencing the "System Web Extension" within the Web Config file shown below, which enables Java Script to be able to reference the Authentication Service classes. I am also calling the function show_confirm in the button onclick event to process the message box response.
I also need to redirect a user back to the Login page within this same show_confirm() function without pointing directly to the URL, but instead to the folder where the page is locateded like in VB Server Redirect if possible.
The error message I receive when I run this code is: Microsoft JScript runtime error: 'sys' is undefined.
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
i currently develop an asp.net mvc 2 web app using asp.net membership and role management for authenticating and authorizing my users. I get complaints though that when adding a role to some user, he is not able to see new role assigned functionality, unless he re-enters (logout and login again) the application.
I have written custom code for login and logout...When use clicks on logout button the current session is closed and user is redirected to a login.aspx page...The problem is that when a user click a back button on internet explorer it the previous page he was navigating is shown to him...(altough he cant perform any operation as session is null and their is condition in page load that if session is null user should be redirected to login page)May i have to clear cache of client ??
I'm new to ASP.NET (only been learning 6 months at college) and have set up a login page with a loginview, login name and login status. The pages work fine on my local machine I can login logout and see the user name etc..But when I upload this to my home testing server the domain name shows up http://mysite/rootfolder/login.aspx, this should read http://mysite/login.aspx. I've set the DestinationPageUrl as both a direct link and ~/admin.aspx and /admin.aspx
This is what I have in the RegisterUser.aspx and yet when the admin registers a new user, then on clickiing the register button, the site logs in as the user who was just created.
Nowadays having activity logs of the system is needed for history and if someone who is trying to mess your site, it is easily to define who is it and when it happen. And even Facebook have it.
how to add notification facility same as facebook in our c# website, clients get the notification on their profile whenever any new feature is aaded to website..?
