Security :: How To Log In With Valid User Id And Password But Failed
Feb 22, 2010
I am a newbie and using Visual Web Developer 2008 Express Edition developing a website with some SQL database and a membership folder.
The membership folder security was set via Website/ASP.NET Configuration and with Permission Deny for Anonymous users, and a user id and password was created.
However when running the website and login with the created userid and password, it failed to log in with error message "Your login attempt was not successful. Please try again." I suspect that the system could not find the ASPNETDB.MDF even though it is in the App_Data folder.
I have separately developed another website with Membership and User Login by following the example in ASP.NET Walkthrough in Learn Web Devbelopment, and it works ok.
A question has been raised concerning password recovery revealing valid user ids. Stage 1 of the password recovery asks for a userid and when progressing to stage 2 will display an error message 'Invalid user id'. In theory this would allow valid user id'sto be identified.Is there a setting we are missing? Something that would allow the user id and question to be asked, then a message saying the 'User/Question combination is invalid'.
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 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 am createing user dynamially with the below code; string MyPassword = Membership.GeneratePassword(8,0).ToString(); Membership.CreateUser(TextBox7.Text, MyPassword, TextBox8.Text); but before I start creating, I would like to check if the user name is used before or not.
Iam new to asp.net.in my web page iam validating user information such as fname,lname,sex,add and also login (to register to website)information emailid and password.here iwant to check email adrress (availblity) and tht iam doing it fine. but when iam validating all the textbox,which are there before emailid something like this
emailid: check (buttonto check email availiblity)
iam using validation controls for all the text boxes , when iam using my tab to enter the values it w,l give me alll error messege until i fill it.and when i reach email textbox and check availblity then i cant check untill i fill the password and retype password texboxes..i can only check the email availblity only when al the fields are valid.but i want to valid the emailid before i could enter password and retype password?
I'm developing an ASP.net 3.5 Intranet Site for a client of mine on my development system. Recently, I copied the solution to my Client's Server across a VPN. I was able to access the home page, but that is all. WHen I attempt to open another page I get the following message. Login failed for user 'ADXXWEB1$'.where AD is the name of the Domain and XXWeb1 is the name of the server.Before a user can access any other page I check the user using a vb.net function. I grab the user from the following lineDim usr1 = HttpContext.Current.Userts Saturday night and my clients are off enjoying the weekend (lucky guys) but I would like to try and do more work. I assume I'm getting this message because the server doesn't recognize me because I'm on the VPN. Is there any way around this?
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'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:padding is invalid and cannot be removedbelow is my web.config:
I have an ASP.Net 4.0 application that is using Forms Authentication and ActiveDirectoryMembershipProvider. It authenticates against Active Directory running on Windows Server 2008 R2.I use ChangePassword control for changing passwords.When the user changes the password he can log on for some time with the old password. My client feels this is a security problem with the application. Is there any way to make sure the old password does not work after the user changes it?Also, if I do iisreset on the web server, the old password stops working. The password must be cached somewhere in the web app.
Is there a way to reset a user's password while logged in as an administrator? I just had to delete a user and re-create him in order to achieve the same affect of resetting his password, so I'm wondering if there is a better way to reset a password.
I've created a login page but when I try to sign in with user name and password, it will not execute.I've gone over the process numerous times and have deleted the user (me) and re-created the user (me).Does anyone have any clues as to what I might be over-looking.
I am using Membership provider.. I integrated the aspnet member tables into my database.
I need the user to enter password on a data entry form and validate it against the membership tables.
How can I do this. This is the set up. I have few fields and user enters those fields and also enters the password, and submits the form. It is kind of like signature... i am looking for something like..
I cannot for the life of me figure out why I cannot wrtite a file to a directory inside of the website. I have this working on a Windows 2003 Server using IIS6. I've ported this web app to a 64bit Windows 2008 server and I am unable to have my web app write a file to a directory. I have shared and given security access to everything under the sun on this server to that particular folder and still no luck. My dev workstation with Visual Studio 2010 has no probelm saving a file to that directory. So it has to be something with the web server account. I am using Windows Authentication. I have an account in our Active Directory that is being used.
