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 am using Forms Based Authentication. I have extended the Forms Authentication Tables creating a custom table called Profile_Contact that holds the user's GUID, username, email address, and other information. I have another table called Profile_Account which holds company account information such as Company Name, address info, phone numbers etc. This table has a Key Field called IDProfileAccount. I include the IDProfileAccount field in the ProfileContact user table so I can associate the user with a specific Company. For the login page, I am using a basic login page created with using the Visual Studio login controls. When the user logs in, they are sent to the appropriate page as identified by the role the user has been given. This all works great.
Now I need to extend the login page so that when the user logs in not only is the user's name and GUID placed in session, I would also like to have the IDProfileAccount record placed in session as well so that I can filter the records the user sees as only those records of the Company the user is associated with. I know how to add static variable to a session and how to retrieve them to filter data, what I need to know is how to retrieve the data from the SQL table on login and sending it to the session. I would think it would be something along these lines:

I 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.
I have an application that has a user Login Control (provided by ASP). I am just now working with the integration of a dataBase created in MS visual studio 2010, to a developed website created in MS visual web developer 2010. My main goal is to create an authentication ticket that enables a user to be able to see a dataBase information only after that user has been successfully authenticated.
Up to now I'm able to see the dataBase when i run the website even if I'm not log-in, how i can create a home page that tells the user to log-in and once that user has successfully log-in it redirects the user to another page where the user can see the database and how I can add information to that dataBase only to specific members
How to create login authentication page using cookies in ASP.NET with C#?
View 1 RepliesI have the following implementation and I'm sure there is an easy way to do what I want to do but I can't figure it out.
1. I use forms based authentication to authenticate to my site
2. I use active directory to authenticate the users
3. I use the Allow Users="xxx" tag to authorize the users limited to the list that can access my site. (e.g.. even though Mary is an AD user she can't access my site unless I put her credentials in the allow users tag in the web.config file)
All is working well but I want to move the users access list (e.g.. <allow users="john" />" from the web.config to a database table so that I can create a user maintenance page for my admins to add and delete user access. For the life of me I can't figure out how to do this and I can't seem to find an article on it either.

when using Forms Authentication to validate against a SQL database, all the Forms Authentication samples utilizes the connection string from the web.config file. Is there a way of specifying the connection string for Forms Authentication to use, programatically at runtime?
Without going into great details, my web app will be utilizing different databases depending upon other factors. So, sometimes, the app will be utilizing Database1, and other times, Database2. Both databases will have the same Forms Authentication tables, just different values.I'm hoping there is a simple way of just specifying the database connection string to utilize, without having to go so far as to start implementing my own custom providers. Yet, I haven't come across any documentation that talks about how to do that (yet).
I wish to create a Single Login Page for the Various Applicatioins i am creating and So i wish to authenticate the Database connection in these other Web Forms (Landing Page) from the url.
http://localhost/Landing.aspx?<Username><Password>
How do i create this feature?? and then extract the username and password on the other web forms??
I am developing a web application which requires user to login. There will be N number of users using website concurrently. We have a MySQL database which will store user information like Name, User ID, Password etc. I am not able to understand on how to check username and password once they enter data using Login form which will be present in DB.

User gets authenticated but the problem is that ASP.NET does not recognise the user as authenticated until the page is refreshed.
I 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 am trying to set up my intranet site so the user logs in with his windows domain account and that account is passed to the sql database to access the database. I have been able to succesfully set up the windows authentication to my website, but when I try to use
<identity impersonate="true"/>
in my webconfig I get a 500 errror on my site when trying to open any page. My server is 2008 R2
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:
[code]...
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?
What do I need to do in order to change an application from Forms Authentication to windows authentication?

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.
