Security :: How To Authenticate User When Enters Password That Should Be The Windows Password
Feb 4, 2010
I just begin creating a website for an organization. First page to be displayed in the login page. I dont have any knowledge in ASP.NET Security. On Login page, i want to display UserName field as disabled with the useralias of the user who currently logged into Windows. Password user has to provide and it should be that user's windows password.
How do i validate that password that user has entered is his windows password?
I´m building a home page where logged in users shall buy products. To be able to get to the buy page the user already has to be logged in. But when he shall execute the buy he has to reenter his password again to check the user a second time. How do I check if his entered password matches his user password? I´m using the ASP Membership library and I have passwordFormat="Hashed".
I am creating a website for reset the password in one of the application from the back end.
I have created a webpage with only one button called "RESET".
If user click the button, it should check the user have already access the application from the "USER" table. If no access, the message appears "You do not have an access."
If yes, next step whether the user have authenticate. If yes update the encrypted password from new table called "UMRESET" to the application table "USER" password.
I have an Intranet web site that uses Windows Authentication and when a users password expires the do not get a prompt letting them reset it. We also have OWA and if they go there to check mail, it sends them to a page which allows them to reset it there. How can I trap for expired passwords and allow them to change it like they can with OWA?
I am trying to implement a small site which requires users to login using Forms based authentication. I have followed the tutorials found on various sites on the net and in particular the one at [URL] This enabled me to get a sample environment in place but it seems as though I am having a problem authenticating a user for which I know the username and password are correct.
I have a ASP.Net 3.5 site with my login.aspx form in a folder named login, my default.aspx in the root of the site and my protected content in a folder called main.
I am authenticating against a SQL Server Express database, so I have ran the aspnet_regsql.exe command to populate my database.
I have added the following authentication/authorization lines to my web.config
I believe that my connection string and my database are ok because if i use the ASP.NET Configuration from within Visual Studio I can create and manage my users and I can also see them in the tables in the SQL Server. Also if I do enter any incorect credentials in my login page the page tells me that the password is incorrect.
I got a username and password field which made by myself and a User database which is all manually made
So now I wish to know how to authenticate user using the username and password data enter by the user and match with the database data to verify user is a member and login?
For what i know, the code should be something like this
SELECT UserName, Password FROM dbo.User WHERE UserName - @UserName
@UserName = ?
How do i assign the value from my username text field to @UserName?
i have a problem with the users authentication on my site. I made <authentication mode="Windows"> in my web.config. The LoginView shows "mycomputermyusername" if i request the page. So far as well. Now i want to login with a different username. Users are stored in an Active Directory. My questions: wich setting i have to do, that user's account and password checked by Active Directory? how can i force the system to make a new login? Logout doesn't work, i always see my on account.
How do I use the FormsAuthentication.Authenticate(Username,Password) method to match against the generated Database?..since as far as I have read, it matches the values against the Web.config.
I have been trying to avoid the windows login userid and password window when I use the Windows Authentication mode for a web site. I need to capture the the windows logon user name without prompting for the user id and password and display that on the web site. I had tried almost everything... changed authentication,security setups on IE and IIS etc... still not being able to avoid the window...
I am using Forms Authentication in a new ASP.NET 3.5 Application.I have created the Tables in my database and run the Web Site Administration Too.When I try to create a user I get a password error no matter what I throw at it and I am becoming sure of that this is a symptom of an a setup error and not a password problem.One of the things that I notice is that my aspnet_Applications is empty and I am not sure what is supposed to fill it.I have tried to delete all the aspnet tables and done the procedure again but with the same result.
I have an ASP.NET website under IIS 6. I am developing on a Windows 2003 server slice. The site runs under windows authetnication.I used to be able to access the site on this server slice but now it prompts for a Windows password. When I type my domain password in I still cannot log into the site.I went under security and changed the setting to allow this server as a trusted site but still the same issue, windows prompt for user id and password.
I had been trying to solve this but there is a hidden key i wish someone point me to.
I had a simple membership database with users in first the Membership Provider configured for clear password to retrieve the original password .
Now a new requirement say that the password must be hashed and reset .
I configure the Membership password to hash , and Implemented the Reset Password Module.
My problem is as follow.
If the user is new registered user with the new configuration the password and the security answer is hashed.
also when I go and reset the password it continue to be hashed.
Now I thought that with new configuration if any previous user with clear text configuration , If he use the password Reset module , because my configuration now is hashed , I expected that the new password and security answer will be hashed . what happen is old user continue in clear text even if the configuration is hashed. so If I had new users everything is fine.
old users Membership Provider somehow know they had been stored in clear text and it keep change password and security answer in clear text . If I delete this user and create it , Membership Provider understand that everything will be hashed. I need to know how it know this , I need to migrate users not to delete and recreate users .
Also if there are no solution for that , I wish Microsoft Consider it in future cause it is a real user scenario, that can happen imagine a business system that related to membership user Id , deleting users and recreate them is not a solution .
My company has some unique password policies (such as a pwd cannot be re-used for 6 months, aside from the must include #, special character, upper & lower case)Can anyone suggest how to go about ensuring that a new user's password complies with these policies (using forms authentication in .net 3.5 framework)?
URL...how we can sending formatted email now in my Login.aspx page i have Textbox that when users forget their password they should type their Username on the textbox and after that click on send button.I want when users click on send button their user name that they type in textbox be on the email that send to me .
I'm using the ChangePassword method of membership provider to change the password and one of the requirement before calling the ChangePassword is to retrieve the current password. But I'm getting error:
I am designing a website (ASP.NET in VB) and I'd like it to have the following features: to generate a random string to be used as a password. This bit I should be able to manage, the bit I don't have a clue on is how I can pass this to a Windows machine (on a workgroup not AD) to change a user's account password.
Using windows Authentication... is it possible to progrematically change a password?
I tried using several ways to do this. I tried using the ChangePassword control. This tells me that minimun characters is 7 even though I have more then 7 characters... I also tried using this method:
[Code]....
The user is always null... and I am assuming this is because this object is indended to use with Forms authentication.
All I want to do is have an option for users to change passwords. Is this possible with Windows Authentication?
