Я использую Active Directory для аутентификации пользователей для интранет-сайта. Я хотел бы совершенствовать пользователей, которые аутентифицируются на основе группы, в которой они находятся в Active Directory. Кто-то может показать мне или указать на меня на направления о том, как найти, в каких группах пользователь находится в ASP.NET 4.0 (VB)?
Я нашел это здесь .
''' <summary>
''' Function to return all the groups the user is a member od

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", & _

Return Groups
End Function

Для тех, кому может быть интересно, вот как я закончил его кодирование:
Dim ID As FormsIdentity = DirectCast(User.Identity, FormsIdentity)
Dim ticket As FormsAuthenticationTicket = ID.Ticket
Dim adTicketID As String = ticket.Name
Dim adSearch As New DirectorySearcher
adSearch.Filter = ("(userPrincipalName=" & adTicketID & ")")
Dim adResults = adSearch.FindOne.Path
Dim adResultsDirectory As New DirectoryEntry(adResults)
Dim found As Boolean = False
For Each entry In adResultsDirectory.Properties("memberOf")
Response.Write(entry)
Response.Write("<br/>")
If entry = "CN=GroupName,CN=UserGroup,DC=my,DC=domain,DC=com" Then
found = True
End If
Next
If Not (found) Then
Response.Redirect("login.aspx")
End If
