Security :: Secure Login Form Without Using WSAT?
Jul 13, 2010
I wish to do a simple and secure login form, for which I have seen tutorials keeping login information and roles set through the ASP.Net WebSite Administration Tool.
Is there any secure way to do a login page without using WSAT at all. provide me good tutorial links for creating a custom login form, having the capability of redirecting to login page if user is not authorized etc.
I don't wish to use the WebSite Administration Tool.

I have a custom mini login user control that I have embedded in the top of my website which shows on every page. These pages are non-secure HTTP://. I would like to avoid having to redirect the user to a HTTPS page to perform the login but I definitely don't want to send login credentials to the server in plain text.
I am trying find a method to send the user's login credentials encrypted via https from a non-secure (http) page.
I tried to set the postbackurl for the login button to itself but in https, but the user's input is not retained and the buttonLogin_click is not fired when I set the button postbackurl property. My ASP.net web application is VB.Net framework 4.0
I am assuming this can be done because I see lots of websites where login fields are on available on every page and they are running http and I can believe they are not encrypting the login credentials.

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>

i was just wondering how much secure is the Login System integrated within ASP.NET ? This is rather vague but i just wanted to know if a website using the system is rather protected to attacks.

My web application will be launched through existing thick client applications. When launched, an HTTP POST request will be generated including information like the userID and additional context information (basically stuff like the target user's name, birthday, etc.).
My plan for authentication is for there to be a look-up table in the database. If the username is already there, automatically login the user, but if there is no entry in the database, redirect the user to an initial login page which will be used to create that database entry.
My question is how to secure this against MITM and other security holes. How can the request generated through the thick client be on an SSL connection? Doesn't an SSL connection have to be authenticated with the username (and password) first? And if so, will the additional context information be publicly exposed until the user is logged in?

I have my database connected into project. Its located on different server. When I am managing users via WSAT everything is ok, it saves users into database on the server and additionally in my local App_Data folder. But when it comes to creating roles it only works with local database, but not applying into database located on the serwer.
Isn't it strange anyway, that it saves data into local database when there is not connectionString for this? I can delete database from App_Data and after doing some action with users/roles it creates new one.

I'm new to ASP.NET. I have a custom login form on my web with login and password fields and OK button. I use my own MembershipProvider to authenticate user. The login control form is in the upper right corner of page and if user is successfully authenticated, I need to display his name and html link "Logout", instead of it.
How can I get programatically user status and use it in condition for displaying login form/login status?

I have created custome Membership Role and Profile provider using INGRES db. Now I can see my IngresMembership and IngresRole provider in the Provider tab(Select a different provider for each feature (advanced) ) of WSAT but when I clik on security tab I get this error:
"There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.
The following message may help in diagnosing the problem: Object reference not set to an instance of an object."
What am I missing? Do I need to add code for all override methods for Role provider? I have just written code for the Initialize and GetRolesForUser functions.

I need to learn the following security-related questions pertaining to ASP.NET membership system (which I am currently using):
1) How to set up "secure" log-in for site members (when other sites say "secure login", what exactly is meant?) --- is that easy for a novice programmer to set up?; are there third parties?; is this done in collaboration with the site host?...Or by using the ASP.NET member system (which I have already set up), is that by default "secure" already?
2) When signing members up, what is best way to block out spammers from the registration process? Is there also third party software I can use? Perhaps someone can give quick answers to these, or point me in the right direction to read a good updated resource on this.

I am working on an e-commerce project using ASP.Net and C#.Net (Visual Studio 2005-Windows XP).
I am facing problems in the login module. I created the login accounts using the roles and users in the ASP.Net Website Administration Tool. The login module is working fine when I test the website within the Visual Studio. I mean the login form is working properly under the Development Server integrated in the Visual Studio. What I want is to make this work properly under IIS (i.e. the Production Server). When I deployed the project to the IIS, the login form with the login control is displayed, but cannot login and gives a login failed message. . I have searched about this issue in Google and they are providing good tutorial links to solve this issue. Even after reading those I couldn't solve this as I am new to Web Development. Can you provide me a sample source code with the web.config and also a description of the major steps in configuring IIS to support the role based login?
I had gone through the following titles under google
"Always set the "applicationName" property when configuring ASP.NET 2.0 Membership and other Providers".

I have read the many posts of people trying to use two different login pages: one for users and one for admins. My question is very different. I have a Site.master page with a LoginView and LoginControl. I then have three root level pages Default.aspx, About.aspx, and Contact.aspx that derive from the Site.master. All three pages are set in the web.config to be allowed to all users. I then have a MemberPage in a Member folder which is only accessible to authenticated users. What I want to have happen is to be able to login from either the Default, About, or Contact pages and then be directed to the MemberPage.

I've encountered a problem with intranet ASP.NET Application using AD Form Authentcation. The login and authorization is built using this KB http://support.microsoft.com/kb/316748. It works fine on DEV but not in UAT and PROD.
Basically, the problem is:1. In DEV, users see login page and they enter domain user name and password and login process happens with no issue.
2. But in PROD and UAT, the same application when the users see the login page (first time) and they submit the login form no response. The login button does nothing. The user closes the browser and come back to login page and it works second time. Strange, this doesn't happen in DEV.
3. Further, on DEV by changing the LDAP path to PROD or UAT, the users can still login the first time. It's only the PROd and UAT that seems to be a problem. Not sure whether it's IIS setting or domain policy or something else.....
Not sure what's causing this issue. The only difference that I can see between DEV and UAT/PROD is:
1. DEV has no load balance but UAT and PROD has.
2. In DEV application is installed under Default Website and on PROD/UAT it's under new website.
The IIS settings has been setup as per given KB. I

I have to make a login form using vb.net. The login form should either accept
Username ID or
Email ID or
Phone number
---- either of one ,and match it with the password of the corresponding record in the user table.
The user table has following column:- U_ID(varchar),mail(varchar),Phone(Number),Password(Varchar)
The form has two textfields - 1. Username
2.Password
And a submit button. If combination is correct I should be redirected to the Index page.
But I don't have to scan through all the columns of the user table to match the password.
(a)If the user enters user_id say- ID 10012 then we should be able to search only the record in the user_id column as it has alphanumeric or varchar data type and match with corresponding password.
(b)If the user enters Email id we should be able to search through the email id column as email id contains "@ and ." sign.
(c)If the user enters phone number then we should search only the phone column as it has numeric datatype.
