この種のタスクを実行するには、 System.DirectoryServices 名前空間を使用します（
DirectoryServicesはLDAP用の管理されたラッパーです）。
Try
' Bind to the users container.
Dim entry As New
DirectoryEntry("LDAP://CN=users,DC=fabrikam,DC=com")
' Create a DirectorySearcher object.
Dim mySearcher As New DirectorySearcher(entry)
' Create a SearchResultCollection object to hold a collection
' of SearchResults returned by the FindAll method.
Dim result As SearchResultCollection = mySearcher.FindAll()
' Create an object to hold a single result from the
' result collection.
Dim resEnt1 As SearchResult
' Get search results. For more information,
' see Getting Search Results.

' This sample uses Try...Catch to catch errors.
' Create an Exception object. For more information,
' see System.Exception.
Catch Exception1 As System.Runtime.InteropServices.COMException
Console.WriteLine(Exception1.Message)
Catch Exception2 As InvalidOperationException
Console.WriteLine(Exception2.Message)
Catch Exception3 As NotSupportedException
Console.WriteLine(Exception3.Message)

You can use a search string such as
"(&(objectCategory=user)(objectClass=person)(sAMAccountName="
+ userId + "))" to search for a user (userID would need to be replaced
with the User's ID).
すべてをまとめて結合するには、以下のスニペットを修正してユーザーのすべてのプロパティを表示します。ユーザー名にのみフォーカスするように調整できます。
