Security :: Prevent Logincontrol From Fullpostback?

Feb 13, 2010

I have a ajaxPopupExtender in where I placed a login control. But when I login i get a full postback. I've tried to put it all in an updatepanel but that didnt help.

What I want is for the client to login from the popup Window, in case of login error I want to show that error message in popup (still visible). But if the login in successful I can in codebehind do a full postback.

As of now, even when error is presented the page is doing a full postback and the popupExtender with login control is collapsed.

Security :: Capture User Entered Password Using LoginControl?

Nov 2, 2010

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).

Store An UserID And Name With The LoginControl?

Oct 6, 2010

I have a LoginControl that works great, however, I want it to store more information than just being authenticated or not. I would like to store the UserID of the user so when they make changes I can call that UserID and record that they made the changes.

Here is my code.

Dim db As New DataClassesDataContext
Dim User = (From UserTable In db.Users _
Select UserTable _
Where UserTable.Active = True And _
UserTable.Name = LoginControl.UserName And _
UserTable.Password = RC.CryptedText _
If User.Count = 1 Then
e.Authenticated = True
e.Authenticated = False
End If

I just want to be able to call the UserID later, I'm able to login and access the pages fine, but something like

Session("UserID") = LoginControl.UserName

Security :: Prevent Past Passwords From Being Used?

Jul 12, 2010

I have to make changes to some existing web applications at work to bring them inline with a new security policy.

I am using the framework 3.5 and am using the standard sql membership provider for user authentication.

When a user is changing his password, I want to prevent him using previously used passwords. What is the best and easiest way to go about this?

I was thinking a SQL table with the following columns, my problem was do I handle encryption here as they are old?

Security :: How To Prevent Creation Of User When Email Is Wrong

Mar 4, 2010

i use the CreateUserWizard in order to create users. generates automatically a password which is sent to the user by email.

The emailaddress must be like this: . If '' doesn't exist in our Exchange server (''), 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 , 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
