Need to know how to Authenticate user in active directory with vb.net 2013 NO asp.net

I just installed Visual Studio .net 2013 pro. I am using Win 7 enterprise.

I am trying to create a concept test program to learn how to authenticate a user against our Active Directory. I am using Visual Basic.Net. NOT ASP.NET

I created a form. On the form there are 3 text boxes and a button.

The text boxes are used to input the domain name, the user name, and the user password.

Clicking the button will cause the program to use the log in info from the text boxes to query AD and see if the account and password are legit. If so a message box will say it is legit, if not a message box will say it is not.

I found some code on one of the many web sites with VB help, actually I have seen variations of it in many places, that looks like it may do the trick for me but Vb tells me "Type 'System.DirectoryServices.DirectoryEntry' is not defined".

I have not found a solution to that error.

The code is as follows...

Code:


Public Class FrmLogin

    Private Sub btLogin_Click(sender As Object, e As EventArgs) Handles btLogin.Click
        If txtDomain.Text = "" Then
            MsgBox("You need to input a domain name", 0, "Missing Domain Name")
            Exit Sub
        End If

        If txtUserName.Text = "" Then
            MsgBox("You need to input a UserName", 0, "Missing Username Name")
            Exit Sub
        End If

        If txtUserPassword.Text = "" Then
            MsgBox("You need to provide a password", 0, "Missing Password")
            Exit Sub
        End If

        If ValidateActiveDirectoryLogin(txtDomain.Text, txtUserName.Text, txtUserPassword.Text) Then
            MsgBox("User: " & txtDomain.Text & "\" & txtUserName.Text & " has been loged in.", vbOKOnly + vbInformation, "Login Results")
        Else
            MsgBox("User: " & txtDomain.Text & "\" & txtUserName.Text & " Could not be loged in!", vbOKOnly + vbCritical, "Login Results")
        End If

    End Sub


    Private Function ValidateActiveDirectoryLogin(ByVal Domain As String, ByVal Username As String, ByVal Password As String) As Boolean
        Dim Success As Boolean = False
        Dim Entry As New System.DirectoryServices.DirectoryEntry("LDAP://" & Domain, Username, Password)
        Dim Searcher As New System.DirectoryServices.DirectorySearcher(Entry)
        Searcher.SearchScope = DirectoryServices.SearchScope.OneLevel
        Try
            Dim Results As System.DirectoryServices.SearchResult = Searcher.FindOne
            Success = Not (Results Is Nothing)
        Catch
            Success = False
        End Try
        Return Success
    End Function

End Class

Any suggestions on how to get this to work would be greatly appreciated.

Thanks,

Ralph
