Security :: How To Create A Customized Login Control And Calls For Membership Authentication
Mar 18, 2010
I just like to know how can i create my own authentication(calling the ASP .net membership, role) page with the same function as the LOGIN Control. Your wondering, why not use the Login control instead. I have my own design and i don't know how to pattern my design to the built in Login Control. I tried editing the login template, but it's pretty hard to pattern it to my design.
This is my design
Basically what would like to know how the Login Control calls for the authentication, and when authenticated, it will pass the user(full name) to my LoginView Control without any coding. Or is it possible that I remove default login button in the LOGIN Control then create my own button and trigger the authentication or validation? But if you have other suggestion that can follow my design and call the authentication, i would be happy to know.
WARNING - Absolute beginner here with VS. I'm expecting a steep learning curve, but I'm up to it! I'm trying to create a website with membership/login. Followed the above walkthrough MANY time, and been very careful with the username and password entered, but I keep getting the message that the loging failed. The asp application name is "Membership" This is the whole thing, automatically created following the walkthrough, apart from adding 2 members - yes, did go to the memberpages folder at the set rules page.
Solution Explorer: Solution 'membership' (1 project) - //localhost/membership/ - App_Data - ASPNETDB.MDF aspnetdb_lpg.LDF - MemberPages web.config - Default.aspx Default.aspx.vb - Login.aspx Login.aspx.vb webconfig aspnet_Membership: (2 members) PasswordFormat = 1 The ApplicationId for the 2 members is different - should it be?..........
I am writing two ASP.NET apps. One is a web service that provides xml data and the other is a web client that will use the service to display and manipulate data. I would like for the web service to do the membership authentication and authorization. Is there any way to simply point the login controls in my client application to the web service instead of to a database. I assume I would have to provide the necesarry methods in my web service interface, which would then use the membership provider database I created and pass the results back through to the client.
Is this possible? I have seen many articles on security provisioin from a web service but none has really been what I am looking for. I was hoping that, since my service and my client are both written in ASP.NET, there might be some built functionality that would benefit me.
I am currently working in an ASP.Net application where i need to implement ASP.Net Membership and Roles. I have used Login controls in my pages. Also I am using a menu in the master page, which is getting data bindings from database. For data bindings I am using XMLDatasource and a transform file (.xslt file). I need to bind the data to the Menu based on the user roles.
My issue is that the generated Menu is not behaving consistently. Sometimes it will show the correct menu for a particular role and some times it will show previously loaded data.Providing my code here:
masterpage.master.cs private void LoadMenuItems() { System.Security.Principal.IPrincipal User; User = System.Web.HttpContext.Current.User;[code]....
I have a business site that I want to use to show clients their projects I am working on. I don't want these projects to be visible to anyone but the clients, so I give them a user ID and password. I want to use asp.net membership to manage the login IDs and passwords, but I want to use jquery to submit the login form (it's lighter and leaner than the login control). Here is what I have: Page with an html form for login .js file with the jquery calls & code in it httpHandler to process the information from the formI have the user to entering their ID and password, I am using jquery.forms.js to process the form, which calls the httpHandler and passes the form values to the handler. I have the handler check to see if the user ID and password are correct, if not, it passes back a message to be displayed to the user. If the user is valid, then I have it passing back the role of the user, which also happens to be the name of the folder the client needs to view. I have the page redirecting via javascript to the client's folder once they are authenticated. I have the location of the client folder setup in my web.config.
The problem I'm having is the page just redirects back to the login page, with the return url included (?ReturnUrl=%2fCTS%2f2010+Design%2fLasmer%2findex.aspx). I want it to go to the client folder (Lasmer in this case) once the user has been authenticated. Shouldn't it send me to the folder's default page once it knows the user is authenticated? Do I have a problem in the way my web.config is wired up, and do I need anything in the client folder's web.config?Here is the code for the web.config:
I am using login control in my website for authentication. after login successfully i am storing value in session variable in session["LoginId"] and after login the template of login control gets converted into loggedInTemplate by calling authentication.redirectFromLoginPage(). But sometimes what happens the login template is gets converted into anonymous template while there is a session value in session variable i.e. session["LoginId"] variable has the value still login control shows anonymous template.
i want to create a login page and i have to use windows authentication. so what are the steps i have to follow to achive login contorl with windows authentication.
I've set up a system with forms based authentication and using the asp:Login control. When I put in an invalid password I get the approriate invalid password message. However when I put in a valid password, it does nothing...just returns to the login page again. I'm triple checked the login info. There is no error message, and the invalid attempts counter doesn't increment. When I put a break point in the Login_LoggedIn event of the Login form, it hits it, but User.Identity.IsAuthenticated is false. I'm not 100% sure it should be true at this point, as I'm pretty new to .NET but it seems kind of odd.
My user database is stored in a sqlserver 2005 db that already existed. I've added a new connection for it.In the authorization I have
I am trying to follow instructions on how to create a login page that tests against active directory. My issue is all of the tutorials seem to be written for ASP.NET 2.0. When I try to follow them I cannot get them to work. Does anyone have any tutorial or information for .NET 3.5 or 4.0?
I am using asp.net authentication and authorization with form authentication for my web application.
When I create a new user using asp.net create user control,the newly create user automatically gets logged in,the already logged users looses his session.
Don't know why this is happening.Is there some setting for this?
I want to put a Login Control and a Create User Control on the same page.. just wondering, before I start am I going to run into any problems by doing this?
I'm looking for a way to create a login control without the use of web admin tool
Here are my system requirements
Windows 7 Visual Studio 2008 Professional Edition Microsoft SQL Server 2005 Express Edition ESET Anti-virus but SQL and Studio files excluded from being scanned. I have got a database. I've created the front end of the user login control manually not using the toolbox. Basically what I need is that once a user has registered. He then logs in. when he enters his username and password how do I code it so the database realises it's him/her and takes them to their LOGGED IN user
I have an ASP.Net application that uses the Membership Login Control. The thing is, we wanted to avoid giving our members more than they need to worry about, so we didn't want to have to make each a custom username. So the thing is, I want to make the Login Control display a DropDown List populated with a list of usernames as opposed to a text box.
implementing login control programmatically using sql server 2005. can anyone give me good web reference about the topic? i am new to this development.
development tool i am using:
>visual studio 2008 > sql server management studio 2005 >windows 7 ultimate(32 bit)
i get all the error message in validation summary except one.the one is if i enter the wrong entry in old password textbox i am getting the error message in literal(ID=Failturetext).i want to show it in validation summary.is ther ary way to do this without the use of event "ChangePassword1_ChangePasswordError".
I need to convert a web site using traditional ASP.Net login,membership/role with SQL to a custom system. I need to use a third party (CAS) authentication system while still using membership and roles to control access to content and User.Identity functions.What would be the best way to accomplish this? I use the <deny> and <allow> user throughout the site to control page access.
I have an old website running fine in Classic ASP with large customer base registered onto the site. The current site allows users to have their own user name(unique) registered against an ID assigned to them. They can change the User name later as well provided it is still Unique in the database(Database is SQLServer2005).
The Problem: Now i want to move the website to .NET and want to use the .NET Membership. I know how to create the database structure in SQL Server through aspnet_regsql script but my problem is how should i import the existing username and passwords as the password stored in MembershipDB is Hashed (salt). Also i might want to allow admins to impersonate as users later.
I am using membership api in my project.I have customized all the controls.Now i want that user can login on only one machine from same username and password at the same time.If user is trying to login on any machine at that time if he is logged in from another machine.They should get message.They should not be able to log in using same username and password on same time on different machine.
How this line if (usrInfo! = null) add another variable that will be used to login.
This line (usrInfo! = null) works, but I have a database table "confirm". If I change in the Admin to "true", the user successfully logged on. If the base table "confirm" set to "false", the user will not be logged.
The following code works if (null! = & usrInfo & usrInfo. IsApproved), but instead of ' IsApproved ', I want to use table "confirm".
Without reading the whole text below, since this is on the ASP.Net side ... basically I think I need to know if there is a way to reduce the size of the forms authentication cookie. When using a DotNet 2.0 website, the ASPXAUTH cookie is about 232 bytes ... when using the same source code but upgraded to DotNet 4.0. the cookie is approximately 264 bytes, setting the ticketCompatabilityMode does not reduce the size since I think the default setting is Framework20. I length of the cookie, including the its' name can not be larger than 256 bytes in order to use it with the "Client Application Services".
I only did a cursory search of the asp.net forums, but will dilligently look for an existing solution.
----- BACKGROUND AND RESEARCH -----
I have been using all three features of client application services (authentication, profiles, and roles) in my windows app (DotNet 3.5 framework) for almost two years now. Up until now, I have not had any problems. This week I hit a brick wall and am pretty stumped with two seperate but related issues.
Issues:
In development, we decided to upgrade our websites/services to DotNet 4.0. All applications upgraded successfully. However we are unable to log into our application using Client Application services. No matter what user we use, Membership.ValidateUser returns false. Since we know the username and passwords, we thought this was strange. When debugging the application, we found that Membership.ValidateUser was throwing an InvalidOperationException (see below for complete exception) stating that the ASPXAUTH property was too long, longer that the schema created in the SQL/CE database. (See below for things tried).
In production .. A user all of the sudden could no longer gain access to the application. Upon inspection, his ASPXAUTH cookie was 264 characters long (9 characters longer than the schemas nvarchar(256)). Even though the user was being authenticated on the "server side", and the JSON query returned "{"d":true}", Membership.ValidateUser returned false. Again, as in the case above, the actual error was ...
I am assuming I am missing something very simple or that I overlooked a settings. In development, this is not a huge issue as I can release the Dotnet 4.0 websites when I am ready. But now that this has happened to a client on a production system, it is very worrisome.
I have implemented the .Net Membership provider with my website which is, for the most part, working well. However, occasionally a user will try and login and nothing will happen. There will be no error, they will just hit "Submit" from the login screen and continue to the homepage as an unauthenticated user. This behavior persists until they clear their web cache, or restart their machine... which makes me think it's some kind of cookie expiration error?
Does anyone have any ideas on how to troubleshoot this?
I am evaluating ASP.NET Membership for an intranet Silverlight app. I want users to be automatically authenticated for my application with their windows logon. Thus I configured Windows Authentication. I would like to store user settings like email-address in using the SqlMembershipProvider and not AD. It seems that storing user settings using the SqlMembershipProvider is not supported with Windows Authentication. Is this really so (using .NET 4)?
If so: What is the rationale behind this? IMHO authentication, user settings and authorization are distinct aspects. User settings could easily be stored (identified by user name) using the SqlMembershipProvider with authentication and password management being supplied by Windows. What is the recommended solution for my scenario?
