Accessing properties in Active Directory

[Guest]

I am having problems retrieving property values from Active Directory using
Visual Web Developer 2005 Express Edition.

I want to populate a form on the company intranet from Active directory and
assign roles to the user logged on depending on their department. To start
with I am just trying to display properties.

I have created a class as follows:

Imports Microsoft.VisualBasic
Imports System
Imports System.DirectoryServices
Imports System.Data

Namespace ADAccess

Public NotInheritable Class ActiveDirectory
Private _Properties As New StringCollection

Public ReadOnly Property Props()
Get
Return _Properties
End Get
End Property

Public Sub New()
Dim Path As String = "LDAP://ou=desktops,ou=domain
users,dc=youngsbluecrest,dc=com"
Dim Entry As New System.DirectoryServices.DirectoryEntry(Path)
Dim Searcher As New
System.DirectoryServices.DirectorySearcher(Path)
Dim Results As System.DirectoryServices.SearchResultCollection
Dim Result As System.DirectoryServices.SearchResult

Searcher.Filter = ("(objectClass=User)")
Searcher.PropertiesToLoad.Add("firstname")
Searcher.PropertiesToLoad.Add("lastname")
Searcher.PropertiesToLoad.Add("department")
Searcher.PropertiesToLoad.Add("telephonenumber")
Searcher.PropertiesToLoad.Add("email")
Searcher.PropertiesToLoad.Add("displayname")
Searcher.PropertiesToLoad.Add("description")
Searcher.PropertiesToLoad.Add("office")
Searcher.PropertiesToLoad.Add("street")
Searcher.PropertiesToLoad.Add("pobox")
Searcher.PropertiesToLoad.Add("city")
Searcher.PropertiesToLoad.Add("home")
Searcher.PropertiesToLoad.Add("pager")
Searcher.PropertiesToLoad.Add("mobile")

Results = Searcher.FindAll

For Each Result In Results

_Properties.Add(Result.Properties.Item("department").ToString())
Next

Searcher.Dispose()
Entry.Dispose()
End Sub

End Class

End Namespace

I have a form with label on it. The page load runs the following code.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load
Dim AD As New ADAccess.ActiveDirectory()
Dim Str As String = ""

For Each Name As String In AD.Props
Str &= Name + vbNewLine
Next

Label1.Text = Str
End Sub

Instead of returning the value of “First Name†I get
“System.DirectoryServices.ResultPropertyValueCollection†for every user in
Active Directory.

The statement Result.Properties.Item("department") returns a
ResultPropertyValueCollection class which contains a collection of
values for that property. To get the underlying value try this:

Dim propertyValues as
System.DirectoryServices.ResultPropertyValueCollection

For Each Result In Results
propertyValues = Result.Properties.Item("department")
-- This check is required to make sure that a value is returned for
the specified property.
If (propertyValues.Count > 0) Then
_Properties.Add (propertyValues.Item(0).ToString());
End If
Next


Hope this helps...
