View 1 RepliesI have a vbulletin forum and want my program users to be able to use their same usernames and passwords they do to login my vbulletin forum. My program is done except for the user authentication. I have searched and googled for weeks now, here is what I know:
� vbulletin 3.8.4 uses, md5(md5($password) . $salt)
� I know how to get the Salt and stored hash from the mysql "user" table.
� I know how to connect to my database without any issues.
I used this code I found here and just modified 3 lines so I could try to get it to work. The code works fine for md5 + salt but as you know I need it to do this: md5(md5($password) . $salt)
Imports System
Imports System.Security.Cryptography
Imports System.Text
Public Class Form1
[code]....
After I can do this I will be able to code my program to retrieve the users salt and compare the hash to the one stored in my mysql database.

View 2 RepliesI have used the code from the link below to create a basic login page in front of the Microsoft Live Single Sing On.[url] I managed to combine the two together(LiveSSO w/Forms Authentication) turning off the Integrated Authentication in IIS from the SSO setup.All works as expected if the user successfully authenticates with AD. THE PROBLEM that I am having is that when the user failes to authenticate it only returns: "Error authenticating user. Logon failure: unknown user name or bad password". This message appears also when the user is set to change the password at next logon. What I want it to do is to read the error code of exactly why it failed so I can setup a redirect to a password reset page (i.e. if error is "User flag is set to change pswd" etc.etc.)From the page linked above you can see the VB code of LdapAuthentication.vb which does the trick of authenticating the accounts or returning the error message if the login fails. The part that returns the "Error authenticating user. Logon failure: unknown user name or bad password." Is handled by this subroutine:

That's what I have been trying to customize to see how it can return a specific code based on the user account AD flags, instead of the generic message

View 4 RepliesI have a WinForms app with SQL05 backend. It has a standard Login window where users are required to supply a username/password. This is validated using my own code and sprocs. Now one of my big clients has scared the bejezus out of me by saying, "Hey Chris, I want you to change your app in line with all our other IT systems so that users can use their common username and passwords with authentication against LDAP". :confused: Having had a moment to reflect, I have some questions (some very noob in nature!)
1. Is this requirement a big deal? :) Or straightforward to implement?
2. Does this mean that when user's double-click my app icon on the desktop, the authentication automagically happens without the need for a Login screen?
3. How on earth can I test this. My dev environment does not use AD, but I do have SBS2003
4. Can anyone point me to good resources about this on the web?

It is simply a "Y" in the road. If they are Company A, then I want to send the username and password over to that website and log them in as if they typed it in there. If they are Company B, then the same thing but with a different website. I do not know the term for this, so the google results are not very pretty.I can not do this with a query string (not that I'd want to anyway) as I do not want the username/pw to be visible.Here is the other weird thing. This can be done via a simple HTML <FORM> and Submit button as I have tested it. But I want to do it all in VB.NET code. How is it that it is possible with some simple HTML but not possible in VB.NET? I guess it could be a security thing, right? What do the good guys like us do when we legitimately just want our employees to go to one login page, enter their username/pw, and then (based on their username) send them to either pageA.aspx or PageB.aspx which receives their username/pw that they only entered once before on the first page?
View 1 RepliesI've been trying to make a app that logs into a website. So far it didn't work for me.I have trouble because:
- The "pin" (username) box on the site doesn't have an ID. (Can't use getelementbyid)
- The picture doesn't have an ID either
Codes I've tried:
With WebBrowser1.Document
.All("pin").InnerText = "mypinhere"
End With
End Sub
This should have, in my opinion, filled in the textbox. Now I need to click the login button?Also I found this in the source of the site:
<img src="/media/img/text_AccountPin.gif" alt="Account Pin" width="93" height="10" border="0"> <input type="text" name="pin" class="form" size="15"> </p>
As we can see, it says
name="pin"
So I should be able to use "getelementbytagname" right?Also, the formId is logmein (log me in)
<form id="logmein"....
This is what I came up with:
Dim webbrowserDocForm As HtmlElementCollection = WebBrowser1.document.GetElementsByTagName("logmein")
For Each curElement As HtmlElement In webbrowserDocForm
Dim controlValue As String = curElement.GetAttribute("Value").ToString
[code]....
in the next code it's tagname is "input" or "text"? Because I found:
<input type="text" name="pin" class="form" size="15"> </p>
Code for filling in:
webbrowserDocForm = WebBrowser1.document.GetElementsByTagName("text")
For Each curElement As HtmlElement In webbrowserDocForm
Dim controlName As String = curElement.GetAttribute("name").ToString
[code]....
It doesn't give me any errors no more, but it doesn't work either.
