View 5 RepliesI have one webserver alone in the network and all the users authenticate in another server. I'm trying to implement windows authentication in a application in the webserver, but every time that the page loads a login window appears exactly that the windows client was authenticated in the order server. Is It necessary both server stay in the same domain? Is there another way? Finally, I need to get the user id in the windows client, but webserver and domain server don't communicated between itself.

View 1 RepliesI have a small website with about 10 members. 5 of those are now banned.
I have ensured that they cannot login through the login page.
However because the authentication cookie is persistent and is set to expire after a few months if they return to the site they will still be logged in.
A simple solution is just to expire all authentication tickets/cookies.
How to create login authentication page using cookies in ASP.NET with C#?
View 1 RepliesI have an asp.net site. Its a mixture of web forms and MVC2.
I have this on 2 different servers which I get to via different urls.
On one server authentication works fine via all browsers (IE 8, FF 3.6, Chrome)
On the other IE 8 fails, it doesn't send back the cookie on the request to the page after authenticating.
Using Fiddler I have seen that both sites attempt to set the cookie, in the response from the login page.
Response Header I see from both servers
Set-Cookie: DemandLaunch=CCA4...E79C2D1; path=/; HttpOnly
Both sites are in the internet zone of IE.
I'm at a loose for what to check now.
I also have a page that sets a cookie via c# code and that cookie fails in IE as well.
The IE issue is not on a single computer either. I see this failure on 4 different computers Internet Explorer.
My urls which I should have included were:
beta.[site].com - works
beta_[company].[site].com - fails
I'm trying to check the Expired property of the user's current FormsAuthenticationTicket to see if the authentication period has expired. But when the period has expired, I'm never able to get enough information to even create the ticket to check. I've tried this:
FormsIdentity id = (FormsIdentity)User.Identity;
FormsAuthenticationTicket ticket = id.Ticket;
But User is null when the authentication period has expired. So that won't work. I've tried this:
HttpCookie authCookie = context.Request.Cookies[FormsAuthentication.FormsCookieName];
FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
But the Forms Cookie is gone when the authentication period has expired, meaning authCookie will be null. So that doesn't work.
Is there any way to actually get the FormsAuthenticationTicket object when the authentication period has expired? There must be, because there's an "Expired" property in the object.
I have an existing website using forms authentication with Sql provider. Now i am trying to integrate with another website and use their authentication mechanism. I am already able to validate a user and trying to silently login the user into my application. Here is the code for "silent" login:

and it works with the exception that Forms Authentication overrides the HttpContext.Current.User by the time i make it "default.aspx". Is there a way to bypass forms role and membership providers?

View 1 RepliesI have developed the authenticated rss feed using the basic http authentication for my site.I also have the admin module for the site which uses the Asp.net Forms Authentication .Both are in the same project.When i turn on the forms authentication module to None in my web.config.My rss feed authentication works fine(the browser pop up the dialog box for the username and password) and upon entering the username and password the rss feed gets displayed.But with forms authentication turn on when i click the rss feed link i am getting redirected to the administrator login page.
If i set my authentication mode to none than the feed works like dream but the admin module do not work as it uses forms authentication.
How can i resolve the conflict for that one.I am using the asp.net mvc filter on my feed contoller to pop up the dialog box for the username and password.

I'm developing an internal booking sytem. Users log in to the sytem and can view existing bookings and search for bookings. They can also create new or edit existing bookings. When completing such actions I need a confirmation prior to completing the booking or updating the recorded. The confirmation is based on a reauthentication of the user.... in otherwords he needs to enter his passord again.
How can I achieve this? The system is internam and I'm using Forms Authentication. I an also using roles as som of the admin forms can only be viewed by administrators.
i want to have several domains A, B, C where a user can enter his username and password to login to a common main domain D.
So the user goes to A, B or C, enters his username and password, clicks the "login" button, and is then on the main domain D in a logged in/authenticated state. Then the user does the things he wants to do, and then clicks the logout-button and is then returned to the original domain that he came from, be it A, B or C.
What is the best way to do this?
I currently use forms authentication in ASP.NET 4.0 (C#).
This could be very straight forward for some of you, but I got caught up. I am doing very simple test - browsing from IIS Manager to see the default page or "under Construction", however I am being challenged to provide my login credential . When I provide my login credential, I am able to see the default page. I wanted to see the default page without providing my credential since Enable anoymous access + basic authentication I am simply wanted to see the default page asit is working on other servers except this one. I have included screen print to make sure may question is clear.
