Security :: How To Achieve Custom Forms Authentication
Sep 27, 2010
In my earlier verison, I used Active Directory to authenticate users which was Custom. In the sense that, I had passed UserName and password along with a token request through datalayer to authenticate against AD. it would eventually check the DomainNameUserName, password against AD and will get authenticated.
I have created a WCF service that will serve as authentication service for Silverlight client.The problem is that when I make a call to FormsAuthentication.SetAuthCookie in the Login method below, I get a null reference exception. I am following the 'Securing Applications Built on Silverlight and WCF' (http://www.componentart.com/community/blogs/milos/archive/2009/05/07/securing-applications-built-on-silverlight-and-wcf.aspx)
I'm looking to implement my own basic webforms authentication. I don't want to use the 'membership' features in this case because I don't want to modify the database schema with all the membership elements that I won't use, and I don't need to support users across multiple applications. I want to wind up with one simple 'users' table that has username, password, passwordSalt, and several other fields to support custom user attributes specific to this application.
but it's rather dated... is this still valid? I'm looking for guidance on what I need to do to implement a custom webforms auth solution. A very basic skeleton I can expand upon, or a good tutorial/guide that illustrates the necessary parts... just the basics..
I created a database for user authentication. After I pass loging parameters to the stored procedure in the database and they return a user ID for that user I use the following line for authentication:
[Code]....
User gets authenticated but the problem is that ASP.NET does not recognise the user as authenticated until the page is refreshed.
I think I'm missing something simple...I have a customRole Provider set up and it seems to be working fine - I can add/change/delete info using the WAT.For my Authorization I do a custom routine that is separate from the .net provider that basically says the users is or is not authenticated (true/false).If the user IS authorized how do I set the cookie (or whatever) letting .NET know who they are so I can use the roles on a directory level?I know I can use Roles.IsUserInRole on individual pages but I'd like to be able to use directory based authorization too (from the web.config).
I've just started a small ASP.NET web application. In this project, I need to authenticate the users with Active Driectory. I managed to authenticate the users successfully with Active Directory. But with Authorization with Custom Role Provider, I'm so confused.You see, the user name and password are stored in AD. So, my approach is that after the LoggedIn event of the Login Control, I check if UserName is not yet stored in the Users table yet, then I will store the UserName there. Eventually, I have all the UserName of the AD users store in the Users table so I can assign Roles to the users.
Let's say I assigned UserA to RoleOne. After he logs in successfully, I do some query to look for his Roles.
Where do I keep the Role ticket? In the Cookie or in the session? How does the authorization of ASP.NET role provider work? I want to store the authentication ticket like ASP.NET role prover does too.
I 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.
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.
I set authentication mode to Windows in the web.config and I enable Windows Authentication and disable the Anonymous Authentication in IIS 7 on win 7, but HttpContext.Current.User is always null.It works fine when I host the web app in IIS 6.0.
I have a web farm web project, and want to make sure windows authentication is working well without any problem in web farm, can any one give me some web sites or information about that?
I needed information regarding the capabilities & integration of AzMan tool with Asp.net.Currently, I got a Sharepoint 2007 website along with ASP.NET 2008 where I am using Form Based Authenication.Now, the requirement is any user within a domain registered in AD should be able to login in website through intranet.
Can I acheive this using AzMan, or I need to create two websites one with FBA for internet users and the other one for the intranet users with AD authenication. Also my intenet website is deployed and in use where usermapping and roles are already created, so using this tool what will be the impact on existing webiste.
I want to use authentication on my site in order to login to the Admin section. I already have my database schema, I don't want to use the ASP.NET membership tables for SQL Server. I have three tables: Employees, Roles, and EmployeesInRoles.
I'd really like to keep this as simple as possible, but I'm having trouble finding a solution. I just want to use forms authentication with my tables so employees can log in, log out, change their password, etc.
I'm trying to get forms authentication working for an mvc site. I have a custom database with a users table, and I would like to do my own password validation. I am logging in my user like this:
if (PasswordHasher.Hash(password) == dataUser.Password) { FormsAuthentication.SetAuthCookie(email, true); return true; }
The problem is, when the session expires obviously the user has to login again. I am thinking I should be storing this Auth cookie in my users table? Update: I'm obviously in desperate need of more education in this area. I just noticed that the user stays authenticated even after an iisreset.
I guess what I'm asking is how can I get persistent and non persistent authentication working properly. I want a user to not have to login again if they click "remember", and if they don't then their authentication should expire when the forms authentication is set to expire.
We have Novell's Access Manager protecting our site. After the user logs in, Access Manager forwards the request back to a web page. On that web page, I need to read a combination of some Basic Auth username information as well as some custom header variablest that AM is passing to the web page. AM will continue to send these variables/values on every page as long as the user stays logged in.
What I'd like to do is create a class that checks for these values to evaluate whether the user is logged in or not. How do I gain access to those variables from a .cs class file?
Unfortunately, all the examples for Forms Authentication Code Behind w/ Custom Role and Membership Providers I find online are written with a VB.NET code behind and I need a C# code behind. I need a codebehind that will do the following:
authenticate user upon login button click if user active_flag=0 (false) OR password!=@password, display error: "Access Denied" if user admin_flag=1 & active flag=1 (true), redirect to admin_pageszipsearch.aspx if user admin_flag=0 (false) & active_flag=1 (true), redirect to pageszipsearch.aspx
I have an older custom classic asp app which handles time sheets for my organization. I would like to start migrate this application to asp.net. I am trying to figure out the best approach to implementing user authentication as the classic asp is built from scratch. For the new site, I would like to use the Login control to handle authentication but not sure the best way to wire it up to the existing SQL database with user name, password, and authentication levels. I have found this code snippit from the Microsoft site:
[Code]....
Unfortunately it does not suggest a connection mechanism. What would be the most logical / standardized way of making a connection to the db?
i have a web site that uses forms authentication. the problem is that i have the site installed multiple times on the same production servers because i need to have a few different login pages (based on the domain in this case). after the domain specific login page, the rest of the site is the same. obviously, this requires a lot of maintenance as each new version has to be installed multiple times on the server (with varying the login page in the web.config file).
so i thought is there a way to install the site on 1 folder on the disk, have a web site on the IIS take in all the needed domains and make some http module (or some other solution) in which i could give it a list of domains and the forms authentication for that domain. this way make the login page used by each site change according to the domain while still having only one site to maintain on the server.
I have to invoke SSIS packages from web service in the most secure way. I think that windows authentication will be secure but i am not sure. I do not have much knowledge about how to achieve this and the information on the internet is very distributed.
We use Sharepoint to control our websites. We build the sites, then load them into the sharepoint server. My question is if I use windows authentication, how can I get my role security in my web config file to coencide with the asp.net controls that use the Forms authentication. Is there a differenence? Our security uses a session variable for security but there is no where to set up their permissions except in active directory. I hope this makes sense because I would like to implement the LoginView with Role groups but how can I give them the role="administrator"? Do I have to go into active directory and give them these permissions(would take awhile due to the size of the company)? Or do I have to set up priveladges in the web.config file for each user(difficult I think)?
I'm writing a simple Intranet application using windows authentication. I want to restrict access to Safe/UCantSeeMe.aspx. I am aware of the AuthorizeAttribute, but this only works on methods. I also found a good post on doing this with the MVC pattern, but I'm not using MVC. This can be done with roles in forms based security. I read on MSDN that using windows based security means roles are based on groups, but it doesn't go into any detail. how can I restrict access to Safe/UCantSeeMe.aspx?
