我使用Active Directory来验证用户身份的一个内部网站。我想改进是基于它们在Active Directory中的组认证的用户。有人能告诉我或点我如何找到一个用户是在ASP.NET 4.0（VB）？

I am using Active Directory to authenticate users for an intranet site. I would like to refine the users that are authenticated based on the group they are in in Active Directory. Can someone show me or point me to directions on how to find what groups a user is in in ASP.NET 4.0 (VB)?

我发现这个的这里。

''' <summary>
''' Function to return all the groups the user is a member od
''' </summary>
''' <param name="_path">Path to bind to the AD</param>
''' <param name="username">Username of the user</param>
''' <param name="password">password of the user</param>
Private Function GetGroups(ByVal _path As String, ByVal username As String, _
                 ByVal password As String) As Collection
    Dim Groups As New Collection
    Dim dirEntry As New _
        System.DirectoryServices.DirectoryEntry(_path, username, password)
    Dim dirSearcher As New DirectorySearcher(dirEntry)
    dirSearcher.Filter = String.Format("(sAMAccountName={0}))", username)
    dirSearcher.PropertiesToLoad.Add("memberOf")
    Dim propCount As Integer
    Try
        Dim dirSearchResults As SearchResult = dirSearcher.FindOne()
        propCount = dirSearchResults.Properties("memberOf").Count
        Dim dn As String
        Dim equalsIndex As String
        Dim commaIndex As String
        For i As Integer = 0 To propCount - 1
            dn = dirSearchResults.Properties("memberOf")(i)
            equalsIndex = dn.IndexOf("=", 1)
            commaIndex = dn.IndexOf(",", 1)
            If equalsIndex = -1 Then
                Return Nothing
            End If
            If Not Groups.Contains(dn.Substring((equalsIndex + 1), _
                                  (commaIndex - equalsIndex) - 1)) Then
                Groups.Add(dn.Substring((equalsIndex + 1), & _
                                       (commaIndex - equalsIndex) - 1))
            End If
        Next
    Catch ex As Exception
        If ex.GetType Is GetType(System.NullReferenceException) Then
            MessageBox.Show("Selected user isn't a member of any groups " & _
                            "at this time.", "No groups listed", _
                            MessageBoxButtons.OK, MessageBoxIcon.Error)
            'they are still a good user just does not
            'have a "memberOf" attribute so it errors out.
            'code to do something else here if you want
        Else
            MessageBox.Show(ex.Message.ToString, "Search Error", & _

        End If
