Security :: How To Compare Login Information With Database
Jul 27, 2010
I have created a login form through VS 2008 using C#. There are 5 different aspx pages in my application.
1)Default.aspx: It contains only a hyperlink to direct the user to login.aspx page.
2)Login.aspx: This page has texbox for Username and Password, sign in button, textbox for displaying error and hyperlink (Create an Account) if the user does not created an account yet.
Here is Login.aspx code:
[Code]....
Now, I want to do following with my application.
If the user already has an account, he can put his username and password and click on the sign in button. If the username is existed in databse, application should compare the user input with database and if both are matched then the application should redirect the user to "welcome.aspx". If username does not exist it should show that Username does not exist.

I have a website that is associated with a PC Application.
The website uses forms security to restrict access to the Information on the PC Application to users with a specific role.
Is it possible to have a link to a page that has sufficient information contained in it to automatically log in and display a page in a restricted area?
I am thinking of something like the confirmation emails you get when registering with a website. They often have encrypted text as part of the link and automatically log you back in to the website when clicked.

I have a third party company that we need to allow they users to pass into our website without loging in. TO keep it easy I was thinking of having them post to a custom login page on my site.
So their code would be something like this:
[Code]....
My landing/login page would do soemthign liek this.
[Code]....
My question is whether there are any security issues when using this kind of method? I am not sure yet what their site is written in. I figured that they could figure out how to do the post as long as I have the landing page for them and there is no security issues.

It has been a while since I've built an entire ASP.NET web application from the ground up but I'm about to jump in again. I've built many individual pages, controls, web parts, etc. recently, but nothting 'soup to nuts' for a couple of years. My question is in regards to login security control. I do not want to use the built in ASP.NET Memberhip functionality for various reasons and already have custom code that authenticates the user, controls passwords, login attempts, etc. I am really concerned though about how to validate that the user is logged in (and the best way to do it). For instance, right now I use a Base page that all of my .aspx pages inherit from. In the OnInit() method, it executes code which includes:
[Code]....
I set the Session["LoggedIn"] object to "true" after the user has successfully been authenticated at the Login.aspx page. So, when a user attempts to access any page in the application, if that Session object isn't true, they will be redirected (you can't visit any page without being logged in). This all works great, but I'm thinking I need something more and that brings me here. First, do I need more? Is this enough? I was thinking about creating a cookie with a GUID value and the SessionID (both encrypted perhaps?) and adding that to my Base page so it checks both the current Session["LoggedIn"] value
and the values in the cookie.

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

I have a online game (written in ASP) which i have finally decided to convert to ASP.NET. However i cannot seem to link the login ID's of users to their specific details in the database. I.E when Joe Bloggs logs in, he will be shown the team information for just his club, not every club. in ASP I use code similar to this below
[Code]....
im not convinced that is the right syntax to be using, but when i execute the code in Query Builder it is showing me the correct data (that i expect to see). So im wondering if there is something else im missing? Is there something extra that i need to be adding in Web.Config file or elsewhere?

So as the title suggested, I'm currently trying to compare the hashed answer in my database against the answer typed in the textfield by the user in the form.
I thought of hashing the answer in the textfield typed by the user first, and after that compare this newly hashed answer to the one in the database (which is already hashed). But when I typed in the SAME answer (before hashing) and hashed it to get the hashed value, by right the 2 hashes (in web form and database) should match? Somehow, it didn't. And I can't seem to get security answer right anymore (even though I typed the SAME security answer).
This is the code behind the button:
[Code]....
I tried in another way too, but still the same thing.

My question: I have a site where '*' users can look at the public directory and '?' users can look at the /Auth directory. It works out of the box as you'd expect. I have the connectionstring un-changed from the VS2010 template ASP.NET (C#) website pointing to the DB file under App_Data. When I run it on my machine on Casini it works perfectly.What I want to do now though is change the data source from the database file to an actual 2005 database. I have a blank 2005 SQL Database ready to use.Is there anything I have to do other than change the connectionstring to point to the database?Will the asp:Login control create the database tables, storedprocedures, relationships, etc.??I tried it (without concentratin admittedly) and it returned with something about schema version stored procedure not present??

I was wondering if anyone knows of a good login stored procedure that can be freely used and features login limits and so on (basically a good one) With my limited SP knowledge, I've tried to create one myself, I haven't completed it yet as I'm not sure on how to compare the last login attempt time against the current time (it's in the comments).
P.S. I had to write this in notepad.

I am trying to modify my current page to have a login. My Current page has the user select a store via a drop down List. This DDL will need to be used as the user name. I would liketo add a Password textbox and the end of the page that the user would just type in there password and hit submit to submit the form is correct or pop-up that passowrd is incorrect and re-enter. I would like to use a Database on my SQL Server to autenticate the passwortd with the store. Does anyone have any sample code that will accomplish this.

I'm in a trouble with the Login Control of ASP.NET to check the credentials against an SQL Database.
I followed all the instructions from [URL] to Login With SQL Server Database but I have errors.
In a master page, I added a Login Control as follows:
<asp:LoginView ID="LoginView1" runat="server">
<AnonymousTemplate>
<asp:Login ID="Login1" runat="server" OnAuthenticate="Login1_Authenticate" BorderPadding="0"
BorderStyle="None" BorderWidth="0px" EnableTheming="True" Font-Names="Arial"
[Code]....
I cannot get this code to work, the are the 2 next errors whent I try to compile:
- Handles clause requires a WithEvents variable defined in the containing type or one of its base types.
- Login1' is not declared. It may be inaccessible due to its protection level.

I am dtrugling with the log in of .net. I have studied a wrox asp.net 2 book and it says add
<authentication mode="Forms">
<forms name="Wrox" loginUrl="Login.aspx" path ="/" />
</authentication>
<authorization>
<deny users ="*" />
</authorization>
to the web.config file. This automaticaly sends me to Login.aspx. The problem I have is I have added this line to the code behind in Login.aspx
protected void submit1_Click(object sender, EventArgs e)
{
FormsAuthentication.RedirectFromLoginPage(User.Text, false);
}
NOW this does not check the password but it should in THEARY send me to the page I was going to. It dosnt it stays on the login page.

question about how to use MS Access as the aspnetdb.mdb during a login and authentication with the use of VS 2010 with framework 3.5. Reason: My current provider does not support MS SQL and only ms Access and MySQL as databases.I wanted to implement a login and authentication and based upon an artikel about ASP.net 2.0 i saw, that basically Access was the first choice in those days.Is it still possible to use Access? and how to implement this?Is this a matter of using connectionstrings inside web.config with Microsoft.ACE.OLEDB.12.0 ?Hope that i get an answer which i understand, since my knowledge about these things is not that big.

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
<authorization>deny
users="?"/><authorization>

It's been a 4 or 5 years since I worked with ASP.net. I dig the login control wizard. But I don't want to use the standard mdf file database. I actually took that database and merged it with mine, tables, SP and views. Now how can I point the controls to update my database, instead of the mdf file it creates? I'm just trying to keep everything in the same database. I'm working on VS 2008.

I have implemented Forms authentication in an ASP.NET MVC 2 website
By using <%: Page.User.Identity.Name %> on the Site.Master page I can display the userid of the logged in user.
I would like to use this value and display other information about the user that is stored in a User table in a MsSQL database, like:
<%: GetFirstname(Page.User.Identity.Name) %>

Usually in sub-folder we will limit the access right to some roles and this feature requires pre-defined database schema.
However, if i still want to use this role feature of asp.net, but I do not like the pre-define database schema, I want to extract role information from my own database table and bind it to the role.
