Security :: How To Prevent Creation Of User When Email Is Wrong
Mar 4, 2010
i use the CreateUserWizard in order to create users. Asp.net generates automatically a password which is sent to the user by email.
The emailaddress must be like this: firstname.name@ourdomain.be . If 'firstname.name' doesn't exist in our Exchange server ('ourdomain.be'), then:
1) the user is still created
2) the message page with: 'Mailbox unavailable. The server response was: 5.1.1 User unknown' appears
E.g: if user John Wayne introduces by error Jhn.Wayne@ourdomain.be , then this user must not be created, and only a simple Alert-message must appear.
I tried a lot of Try / Catch / Endtry but all my attempts fail: the user is always created and the whole message page appears. I also tried with CreateUserWizard1_SendMailError sub.1
Here the aspx file:

I have this web application (LAN) that sends an email when users registers to one of our events.
The code is pretty straightforward:
[code]....
The application sends the email without problems. The issue is that somehow a third person is enlisted in the cc, and receives a copy of the email!. What could be the problem? The smtp? IIS?

I have made an asp.net 3.5 website where I am using the membership in order to generate users. I have used the CreateUser Wizard that is available with the ToolBox . The problem which I am facing is that as a Person Completes his registration and redirected to the Default Page, He is automatically Logged Into the website. I dont know how is it possible to skip this step. Pls suggest so that after the registration the user need to go to the login page and use the Login Control in order to Log into the site.

Is there a way to run an SQL statement (or stored procedure) at the successful completion of a Create User process?I'd like a user to be able to create their login profile and upon completion automatically run a SQL statement to pre-populate some other tables.I'm using 3.5 and the have a create user wizard control on my page. I'm working in VB, and am a bit of a n00b with it.I'm thinking I need an onClick somewhere, but frankly I'm not sure how to go about writing it.

I was/am struggling with security for my first MVC applicaiton. It worked out great for me, but not for my users. I wanted to use Windows Authentication (and I seem to have that working). But when I was still trying to implement it, I was on one of our users computers where they were logged in. I navigated to the main Index page and used the supplied MVC login link and *MY* credentials. So now every time that user navigates to that page, it logs her in as me. We are using IE8, I have deleted all the cookies, passwords, forms information I can fine through Tools|Internet Options|Tool|Content|AutoComplete.

little addition : <siteMapNode roles="*"> appears to all nodes If I don't do roles="*" on main node, all users can't see Main node ... And I SiteMapDataSource works only if there 1 node

Since I need user click a link from his/her email once they registered, currently after user registered, and click the "Continue" button (CreateUserWizard1_ContinueButtonClick) or CreateUserWizard1_UserCreatedSuccess, it will be authenticated, how do I prevent this until they click the active link from their email?

Using vb.net/asp.net 2005.
I am modifying an existing page where I am doing an insert into tables, adding an email address for the team, both fields input from the user.
However, Each email can only exist once for a given team (I have a unique index constraint in my code) so when this exception happens I am showing text something like "you cannot add the same email address for this team" and I am also changing the following property of my CreateUserWizard:
[Code]....
before this it was displaying something like "you have successfully created your user..."
However if the user attempts to add the same email address again for a given team I want to prevent the user from registering.
Anyways, my question is that its good I am hiding the "successfully created..." text however I am still seeing the following:
1. "Complete" word
2. A button with the text "Continue" on it.
I also need to hide both the "Complete" text and the "Continue" button.
This is confusing to the user because it suggests that the user was created successfully but this is not the case in the scenario I described.

My application is windows authenticated. The application pulls JUST the userName from the current windows account. Then I provide site access to this user depending on his account privileges. If his userName belongs to the admins list he is directed to admin screens. If his username belongs to users list he is directed to users screens. I handle this security in C# and some SQL tables(No membership provider and no Active directory security in the app).
I need to be able to prevent multiple concurrent logins for the same userName.

I have a weird thing happening. I have two identical databases installed on one virtual machine but under two different instances of SQLServer. For some reason, periodically when saving from one it will save to the other instead. Using debug, I have verified that the connection string is correct and when the item saves, it still saves to the wrong database.I use session variable, and am of the belief that it might have something to do with it...and t hat when I go from one to the other it is still getting the connection string form the other for some reason.To make sure that it isn't a problem, I make sure that I completely close out one database before opening the other in a new IE window.I assume that when I completely close out an internet explorer window that it abandons all session states. Is that true?

why the email attachments that my application sends sometimes ( maybe 1 out of a 100) come in the text format. Rather in raw markup format, not rendered?

change details of a user ( asp.net membership change email of a selected user ).
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Protected SubButton4_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button4.ClickTry Email = EmailTextBox.Text Membership.UpdateUser() updateuserlabel.Text = "User e-mail updated." Catch u As System.Configuration.Provider.ProviderException
updateuserlabel.Text = MessageEnd
End Sub
This works but what is does is to load the email of the user that is login to the textbox and then if i press the button it changes to the text assign to the textbox.What i want is to choose from all the system users and then change the email of each.

I have been searching since some days for the best approach one can have in order to allow an authenticated user to change his/her email address.
This is the code I have but apparently it doesn't work and it doesnt even gives a error. The application seems to ignore it:
Change email address:
<asp:TextBox ID="txtEmail" runat="server"></asp:TextBox>
<asp:TextBox ID="txtPassword" runat="server"></asp:TextBox><br />
<asp:Button ID="changemailbtn" runat="server" Text="Button" />
<asp:Label ID="lblErrors" runat="server" EnableViewState="False"

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.
