NT Domain Account

[Dooza]

Hi there,
Using classic ASP I want to check if a username and password are correct
before passing the details on to an object (stocktake module) that uses
them to authenticate the object. The object defaults to a preset user if
the authentication fails and doesn't warn the user, so I wanted to do
the check manually before passing it to the object.

Does anyone have any resources?

Cheers,

Steve

You will need to create a COM object to do this, it can't be done in script.
On the bright side, the code to accomplish this is fairly trivial, all you
need to do is call the LogonUser API. (Note that if it succeeds you should
close the token handle it returns.)

If you wanted to do it in VB6, it would look something like this:
Public Declare Function LogonUser Lib "kernel32" Alias "LogonUserA " (ByVal
lpszUsername As String, ByVal lpszDomain As String, ByVal lpszPassword As
String, ByVal dwLogonType As Long, ByVal dwLogonProvider As Long, phToken As
Long) As Long

Public Declare Function CloseHandle Lib "kernel32" Alias "CloseHandl e"
(ByVal hObject As Long) As Long

Public Const LOGON32_LOGON_N ETWORK = 3
Public Const LOGON32_PROVIDE R_DEFAULT = 0
Function ValidateCredent ials( _
UserName As String, _
Password As String, _
Domain As String _
) As Boolean
Dim hToken As Long

If (LogonUser(User Name, Domain, Password, n, n, hToken) <0) Then
CloseHandle hToken
ValidateCredent ials = True
End If

End Function

Hi Mark,
Thank for the code, I wish I knew how to make a COM object, but will see
if a friend can do something with this for me.

Thank you!
