I dont know where to post this message so here it goes.

I am setting up a forum on my lan. I dont want my users to register to access the forums. The usernames and the encrypted passwords are stored in a Windows 2000 server. So what I want is to make the users login without registering. The username and password should be checked against the ones in the Windows 2000 server.

I dont know how to do this. Could anyone please help me out with this.

Thanks,

Denesh.R

If you do a search of the forum there are a number of posts on this issue as I don't have the time at the moment to run through how to alter it for NT authentication at the moment.

Hey guys,

I figured out how to do this and i hope that anyone else who stumbles upon this problem will find this solution usefull

This code is supposed to work in the Windows 2000 as well as Window NT.

I use a function which changes the password. The function needs the Old Password as well as the new password. So the trick is to pass the old password for both parameters so the actual password will not be changed. The function itself will first validate the oldpassword. So we end up having a function that validates the usernam and password entered.

This code should explain it all.

I put this bit in the register.asp file


 '******************************************
 '***   Check Password Against Windows ***
 '******************************************
 'If in update mode we dont have to check password against windows
 
If strMode <> "update" then
 Dim NTServerName, Uname, Passwd, objUser, ErrorCode
 NTServerName = "cateye"
 Uname = strUsername
 Passwd = strPassword

 On Error Resume Next
 Set objUser = GetObject("WinNT://" & NTServerName & "/" & Uname & ",user") 
 objUser.ChangePassword Passwd, Passwd
 If Err <> 0 Then
  If CLng(Err.Number) = CLng(-2147024810) Then
   ErrorCode = "Your password was incorrect. Enter the password that you use to logon to the network"
   Response.Write("<script Language=""VBScript"">" & vbCRLF)    
   Response.write("MsgBox """ & ErrorCode & """,,""Invalid Password""" & vbCRLF)
   Response.Write("Parent.Navigate ""default.asp""" & vbCRLF)
   Response.Write("</script>" & vbCRLF)
   Response.End
  ELSEif Clng(Err.Number) = CLng(424) Then
   ErrorCode = "Invalid User Name. Enter the username that you use to logon to the network"
   Response.Write("<script Language=""VBScript"">" & vbCRLF)    
   Response.write("MsgBox """ & ErrorCode & """,,""Invalid Username""" & vbCRLF)
   Response.Write("Parent.Navigate ""default.asp""" & vbCRLF)
   Response.Write("</script>" & vbCRLF)
   Response.End
  Else
   ErrorCode = "An unexpected error has occured. Please try again"
   Response.Write("<script Language=""VBScript"">" & vbCRLF)    
   Response.write("MsgBox """ & ErrorCode & """,,""Unknown Error""" & vbCRLF)
   Response.Write("Parent.Navigate ""default.asp""" & vbCRLF)
   Response.Write("</script>" & vbCRLF)
   Response.End
  END IF
 ELSE
  ErrorCode = "You have been authenticated successfully"
 End If
End if

If anyone can improve this code then please let me know

Thanks.
