I've created a website with users and passwords and such for authentication.When a user is created through the "administer website" function of asp.net 4.0 where are the passwords stored? Is there a way to manually change passwords in the database?

[Code]....
I do not get an error during the try routine, but my problem comes that when the user goes it insert their new password (using login Control) it says that the password is wrong.. and they then can't login using either their new or old password.
All Password critria is met, web.config if set so passswordQuestion = false
My issue today is that i have a MySQL Database and am using the security framework provided by the ASP.NET Membership and Role Providers...I override the default methods with my own MySQL.
Now the issue comes in when i someone would like to have their password reset. My application is running entirely on an Intranet so i cannot have their passwords emailed to them. Is there a way i can have this information displayed in any way so that the user can use it to Log Reset, Create Accounts or Recover their lost passwords on an intranet without the administrators intervention?
Recently i had an approach as follows. In my web.config<system.net><mailSettings><smtp deliveryMethod="pickupDirectoryLocation" and my location was a folder on C drive as c:/SavedPasswords. Now i understand this was such a big security threat and thats why i am looking for a better option.
I would have that folder created using my System.IO and then the Mail is dropped into that folder. Then after the process is successful, i tell the user to check into that location and Read its content.
Then there is a global variable that is set to true...meaning that the folder at c:/ has been created. then there is a Method in a certain class that once it sees this variable True, it reads the readers c:/ and deletes that folder "save" if it exists;
I have a small database, with a very small number of users. The passwords were stored as clear as the database was so small and held no sensitive data. The database is now to be expanded and passwords are required to be encrypted. I can change the Password Format in the web.config, but is there a way to change the existing passwords from clear to encrypted?

I am trying to create an Intranet application and I want my users to be able to log in with their windows account. However my organisation has over 150000 employees but I only want the 10-12 people in my department to be able to log in.
How do I do this? Do I need to store the 10-12 users in a database?
I am using windows authentication in my web application. All we need is when the application will be executed it will launch login.aspx page. If users put correct userid and password(checked from active server directory) it will be redirected to a difference page. But if any unauthenticated user tries to access any other page in the application by typing the Url on the address bar it will be again redirected to the login page. We have to do this by changing our web.config file.I can achieve this using form authentication but not windows. But our requirement is windows. The requirement is very basic but all effort is just not working.
View 2 RepliesI set up forms authentication in my asp.net application, and everything works apparently without problems. However from time to time some of the users trying to log in inform me that suddenly they cannot enter anymore as their user seems to be deactivated. Even if they try the forgot password entry, they get "user not found" response, but if I check the user is still there, and according to asp.net configuration it is even active.The only solution I found until now to reactivate the user is to remove it and create it again, and then it works. But it cannot work like this of course.
View 5 RepliesI want to know how to do Active Directory Authentication in my intranet web application,
So far I created a simple login page and I am using the login control. my questions are how do I configure the application, how do I interface the login control so it will take the user to next page once they input their usual active directory username and password.
I created a Membership login system for my client, now they do NOT want the user to use one of his 5 last passwords when it comes time to create a new one.
Is that something that is build in or how could I accomplish that?
For some reason my users are logged out of the system every 10-15 minutes or so...regardless of the configuration below....am I missing something?

I have an intranet site that i set up to windows authentication. It works fine most of the time but some departments wont be able to access the site and will be asked to enter user name and password.I checked their Active Directory account and the only difference i could see was that the organizational unit parameter was different than the rest of the users.
View 5 RepliesI have the following implementation and I'm sure there is an easy way to do what I want to do but I can't figure it out.
1. I use forms based authentication to authenticate to my site
2. I use active directory to authenticate the users
3. I use the Allow Users="xxx" tag to authorize the users limited to the list that can access my site. (e.g.. even though Mary is an AD user she can't access my site unless I put her credentials in the allow users tag in the web.config file)
All is working well but I want to move the users access list (e.g.. <allow users="john" />" from the web.config to a database table so that I can create a user maintenance page for my admins to add and delete user access. For the life of me I can't figure out how to do this and I can't seem to find an article on it either.
[code]....
I've got a system that was partially written by someone else and is a complete maintenance nightmare for such a small app. I've finally been given changes which justifies just rewriting the horrible mess so I am moving it to Django.
Before I take the plunge, I've been trying to move over the password hash and salt into the Django auth tables [sha1]$[salt]$[hash] but can't get it to hash properly (resetting passwords isn't really an option).
Here is what I've been able to find out so far:
ASP.NET stores the hash as base64 string and uses a base64 salt (before hash) I can obviously reverse the base64 hash to a byte array Django uses a hexdigest, I tried BitConverter.ToString but they hash differently
according to this thread i make login page URL....i have 1 label 1radiobutton and 1 send button now i want when users enter their password,if they enter their password wrong morethan 3 time it show error that they can't login during 24 hours ,and they cann't enter password in password textbox . and when they click on radio button and click on send button it send a massage to my email and after i send them new password
View 1 RepliesIm not sure what it is called, but I need help with this. I need some tips on how to get started on an ASP.net site that will have different users. When each user logs in, they will be able to enter their own personal information such as address, hours worked, their own timesheet etc. I want to have it so each user will be able to only see their own data, not any other data entered by other users. I hope I am describing it ok. Please let me know what this process is called, or any good ways to get started on this.
View 3 RepliesI am using database with a list of username/passwords, and a simple web form that allows for users to enter their username/password.
When they submit the page, I simply do a stored procedure check to authenticate. If they are authorised, then their user details (e.g. username, dob, address, company address, other important info) are stored in a custom User object and then in a session. This custom User object that I created is used throughout the web application, and also in a sub-site (session sharing).
My question/problems are:Is my method of authentication the correct way to do things? I find users complaining that their session have expired although they "were not idle", possibly due the app pool recycling? They type large amounts of text and find that their session had expired and thus lose all the text typed in. I am uncertain whether the session does really reset sporadically but will Forms Authentication using cookies/cookiless resolve the issue?
Alternatively should I build and store the User Object in a session, cookie or something else instead in order to be more "correct" and avoid cases like in point #2.If I go down the Forms Authentication route, I believe I cannot store my custom User object in a Forms Authentication cookie so does it mean I would store the UserID and then recreate the user object on every page? Would this not be a huge increase on the server load?
asp.net 3.5 IIS7 Hosted on Windows Server 2008 (virtual machine)
I have a website which have been running for about a year without any problems. Users have been able to login etc, but now I get reports about users not able to login while using Internet Explorer. Users using other internet browsers like FireFox, Chrome etc have no trouble logging in.
The website are using the standard Forms authentication.
Also lately another website has been setup in IIS7, but these sites are using application pool. I've stopped this webapplication in IIS, but that doesn't have any effect on my problem
I see that Windows Update have failed to install a lot of patches lately, not sure if that is related to this problem. But some of the windows patches are security patches.
i have a search box, many text boxes which taken various inputs and save it to database using primitive methods such as "insert into....." executenonquerry etc.have read something that " a textbox by itself can prevernt attacks known as sql injections" is that true?if sohow to enable it?does it need extra coding?

View 2 RepliesI am using login control in my website for authentication. after login successfully i am storing value in session variable in session["LoginId"] and after login the template of login control gets converted into loggedInTemplate by calling authentication.redirectFromLoginPage(). But sometimes what happens the login template is gets converted into anonymous template while there is a session value in session variable i.e. session["LoginId"] variable has the value still login control shows anonymous template.
View 1 RepliesHaving spent considerable amount of time in ASP.NET security community I would like to share this.
There are three ways of resetting and changing passwords explained at
Microsoft ASP.NET site[URL]
Step 1: Helping Users Recover Lost Passwords
Step 2: Changing Passwords
Step 3: Allowing Administrators to Change Users' Passwords
In step 1 and step 2 end user passwords are sent by an email.
In Step 3: functionality is explained where administror changing the password and sending through email msg. refer "I encourage those readers interested in this functionality to become more familiar with the code and try extending the functionality to include sending an email to the user whose password was changed. Query
Is Sending passwords by emial secure enough or best security password at all? I have implemented functionality where Admin sending passwords to end users by changing once in 3 months. End users expressed their views that sending passwords by email is not secure. When there is security threat in sending passwords by email, Microsoft security experts should not emailing passwords in above mentioned article, which is still up to date.
I have a mvc2-website with windows authentication.
<authentication mode="Windows" />
<authorization>
<allow users="*"/>
</authorization>
In IE the website keeps asking several times for my credentials per webpage. In Firefox it works correctly.
We are having an issue with the windows authentication and IIS restart for asp.net application Our environment is an intranet site (an asp.net application ) that uses windows authentication, uses integrated security application pool, physical path credentials are set for a service account, who is admin for sql server, IIS etc. web.config - Connection string has Integrated Security = true, authentication = Windows, and authorization - deny *, allow = security group. Anytime we start - stop service (or restart) (IIS); and hit the website thru some other machine IE, it fails to show the website (401.2), and any subsequent hit to the website doesn't go thru.
However when we start the service, and hit the website on server's (where website is deployed) browser first time then everything works fine for subsequent hits from anywhere as long as authenticated on corp net and member of security group configured in web.config. This behavior however goes away if we uncheck the configuration "Enable Kernel-mode Authentication" on the asp.net application. ( but then Firefox browser stops working with this configuration!!) Why such behavior? In the documentation it states its recommended to keep it enabled. What is recommended way of publishing a website with windows authentication enabled? Any side effects of "Enable Kernel-mode Authentication" being unchecked ( other than what we found for firefox not working) Environment : IIS 7.5 windows 2008 Server R2, VS2008, SQL Server 2008, ASP.NET 2.0
