Security :: Form Based Authentication And Session Variables
Apr 19, 2010
I am using form based authentication in one of my website. I issue AuthenticationTicket on successful login and use this ticket to validate request. but now I need to store other variables immidiately after authenticating request (just like adding session for username, email etc. variable after successful login).
My question is if I make use of session to store variables, do I need to concern about it as form based authemtication is cookie based and it is not related with session timeout.

I have a question regarding Form Authentication Session Timeout
I have a form authentication and i have set the session timeout in my webconfig.
After I login to website using my form authentication, the session is not timing out even after i login more than 30 minutes.
It seems i'm still authenticated and can access everything.
Is it normal ? I thought if we set the timeout in webconfig it will automatically log you out because the session expire.
<authentication mode="Forms">
<forms name=".authentication" loginUrl="Login.aspx" defaultUrl="Default.aspx" protection="All" timeout="30" path="/" requireSSL="false" slidingExpiration="true" enableCrossAppRedirects="true" domain="" />
</authentication>

I want to password protect an area of a website by a login/registration form.
I'm using session variables to check wheter the user is logged in or not. I already have a database with users/passwords... so I thought that the membership approach wasn't an option... (correct me if I'm wrong)
in the constructor of the controller of the area I want to protect I've added the following:
[Code]....
but this throws an error:
Server Error in '/' Application.
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 or 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]....
Line 28: this.productsRepository = productsRepository;Line 29: Line 30: if (Session["user"] == null)Line 31: RedirectToAction("List", "Products");Line 32: }

I am doing web based projects in dotnet. Currently I am implementing security using session variables. I keep current user id and user type in session and authenticate user from these session variables (say Session["UserId"],Session["UserName"] and Session["UserType"]).
I've heard that such security can be broken and applications can be hacked very easily, like it is possible to get session id and directly connect to that session id etc.

In my asp.net website in VS-2005 with SQL-Server 2005 as db, I need to implement role-based Authentication/Authorization.
I am familiar to the practises used in role-based authentication..as I have previously worked on projects that used this method. However, my project lead used to design the database. Now I have an existing website where authentication has been set to anonymous by setting 'allow users="?"' in the authentication tags in web.config.
If I use the createUserWizard control and use the Membership.creatUser(.....) method in code behind will the asp.net security tables, like users, roles, userinrole etc get created on its own?

I am trying to implement a simple role based authorization using forms authentication in ASP.net. It works perfectly fine in my local system but fails when I deploy in production (shared hosting). Whenever I try to log in, rather than taking me to the default page in specified directory it throws me back to the login page. I suspect that there is some issues with the configuration but not sure where the problem is. The code is provided below:
Web.config (root):
[Code]....
Web.config (Member directory):
[Code]....
Login.aspx:
[Code]....
Global.asax:
[Code]....
Works fine in local machine but shared hosting is not taking the authenticated user to the pages inside the secured folders. What can be the issue?

I want to create a web service that can authenticate user from my application. I will be sending user name and password from my app to the web service and that will deny or accept the user. I want to use form authentication using sql server. that this web service can be used by other team in my office so that they can just call the web service and the user will be authenticated.
Also, is it possible to use both form and windows authentication in my web service and authenticate the user both ways.

Is there any way that I can create a session variable AFTER authentication? It needs to be populated from the users record in a sql database. Basically I tried using Application_AuthenticateRequest in global.asax with an application variable but this made it available to all users. Using session_start is not working as when this runs my user is not currently logged in, so the variable is always empty when I try and grab it's value.

I 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.
