Security :: Both Old And New Password Work After The User Changes It?
Nov 14, 2010
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.

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 have the following code. I simply want to select the security question and answer from the DB and do something if the result is true.
This is my code:-
[Code]....
This code always returns the result of "Invalid User Credentials", so this means it does not recognize the values from the DB. When i put something in that SHOULD match i still get the same. I dont get an error message but the logic here is to select security question and answer where the question is equal to the dropdown box and the answer is equal to the textbox. If there is a match then do something..
But this does not work..
You can see what i mean here:-
[URL]
If you select "What street did you grow up in?" from the dropdown and then put in "deeplish" in the security answer, the result should be "**EXISTS".

It seems to work just fine but it resets the users password, emails it to them and then the user can not log in with the new password.

By default the Password Recovery control requires the username to send the user the login details. Is there any way I can configure it to work with either the log in name and email address or failing that just email address?

I have a custom membership user class and custom MembershipProvider working against database. Due to security reasons the user passwords are stored in the database as hashed values. So my procedure
public override bool ValidateUser(string username, string password) is
{
//select hashed password from db
return (EncodePassword(password) == dbpassword)
}
[code]....

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.

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.

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'.

Our user is using integrated windows authentication.
All users hit the login page where they must login with their domain/username/password combination.
Once they login, they can change their password.
Once the password is changed, they are displayed a message and they can navigate through the rest of the site.
I get the following scenarios...
1) User can view one page but not a second page User changes password USer clicks on link and receives page USer clicks on second link and is asked for credentials
2) User can view all pages USer changes password User clicks on link and receives page User clicks on second link (and all links thereafter) and receives page (they are never prompted for credentials)
3) User can not view any pages
User changes password USer clicks on link and is asked for credentials

I have only username. and want to check and grab the password from the database. It is BEFORE LOGGING IN. so I don't think the build-in asp.net functions could be used, right?

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.

We use the LoginControl to authenticate our users. For this particular site, security isn't a HUGE concern but the Membership provider allowed us to customize the users menu and do some other handy things.
Lately, our Customer Service department has been complaining that there is something wrong, because many users are being "locked out". What I would like to do is capture the login and password (I know how to get the login) and log it to our SQL database. Is there a way to get the un-encypted password? I am pretty sure there isn't but thought someone might know a workaound (without using a custom control of something of that nature).
