ho creato una form chiamata login con il classico button 1.
sull 'evento click ho inserito questocodice
codice:
Imports System
Imports System.Text
Imports System.Collections
Imports System.DirectoryServices
Public Class login
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Namespace FormsAuth
Public Class LdapAuthentication
Dim _path As String
Dim _filterAttribute As String
Public Sub New(ByVal path As String)
_path = path
End Sub
Public Function IsAuthenticated(ByVal domain As String, ByVal username As String, ByVal pwd As String) As Boolean
Dim domainAndUsername As String = domain & "\" & username
Dim entry As DirectoryEntry = New DirectoryEntry(_path, domainAndUsername, pwd)
Try
'Bind to the native AdsObject to force authentication.
Dim obj As Object = entry.NativeObject
Dim search As DirectorySearcher = New DirectorySearcher(entry)
search.Filter = "(SAMAccountName=" & username & ")"
search.PropertiesToLoad.Add("cn")
Dim result As SearchResult = search.FindOne()
If (result Is Nothing) Then
Return False
End If
'Update the new path to the user in the directory.
_path = result.Path
_filterAttribute = CType(result.Properties("cn")(0), String)
Catch ex As Exception
Throw New Exception("Error authenticating user. " & ex.Message)
End Try
Return True
End Function
Public Function GetGroups() As String
Dim search As DirectorySearcher = New DirectorySearcher(_path)
search.Filter = "(cn=" & _filterAttribute & ")"
search.PropertiesToLoad.Add("memberOf")
Dim groupNames As StringBuilder = New StringBuilder()
Try
Dim result As SearchResult = search.FindOne()
Dim propertyCount As Integer = result.Properties("memberOf").Count
Dim dn As String
Dim equalsIndex, commaIndex
Dim propertyCounter As Integer
For propertyCounter = 0 To propertyCount - 1
dn = CType(result.Properties("memberOf")(propertyCounter), String)
equalsIndex = dn.IndexOf("=", 1)
commaIndex = dn.IndexOf(",", 1)
If (equalsIndex = -1) Then
Return Nothing
End If
groupNames.Append(dn.Substring((equalsIndex + 1), (commaIndex - equalsIndex) - 1))
groupNames.Append("|")
Next
Catch ex As Exception
Throw New Exception("Error obtaining group names. " & ex.Message)
End Try
Return groupNames.ToString()
End Function
End Class
End Namespace
End Class
l'errore generato è "l'istruzione non può trovarsi nel corpo di un metodo.verrà interpretata come fine del metodo".
in piu non ho capito come fa a prendersi i dati inseriti nelle textbox...
