活动目录搜索不返回所有用户

Question

我有代码来填充VB.net应用程序中的用户id下拉列表。一些用户名不会被返回。我得到1000多个返回，所以它似乎不是1000的限制。如果我将（sAMAccountName = Kry *）添加到搜索过滤器，则返回未出现的用户（名称以kry开头）。任何帮助，将不胜感激。谢谢！

Private Sub PopSecurityUser() 
    cboUser.Items.Clear() 

    Dim SearchRoot As DirectoryEntry = ActiveDirectory.Forest.GetCurrentForest.RootDomain.GetDirectoryEntry '< More portable. Discover domain root DirectoryEntry rather than hard coding a Global Catalog. 
    Dim AdObj As System.DirectoryServices.SearchResult 

    Dim Searcher As New DirectorySearcher(SearchRoot) 

    With Searcher 
     .PropertiesToLoad.Add("sAMAccountName") 
     .SearchScope = SearchScope.Subtree 
     .Filter = "(&(!objectClass=contact)(objectCategory=person)(objectClass=user))" '< Exclude contacts because they don't have a sAMAccountName property. 
     .ReferralChasing = ReferralChasingOption.All '< Causes lookups to follow LDAP referrals if the object doesn't exist on the queried domain controller. 
    End With 

    For Each AdObj In Searcher.FindAll 
     If Not IsNumeric(AdObj.Properties("sAMAccountName")(0).ToString.Substring(0, 1)) Then 
      cboUser.Items.Add(AdObj.Properties("sAMAccountName")(0)) 
     End If 
    Next 

    cboUser.Sorted = True 
End Sub

DirectorySearcher.SizeLimit属性默认设置为1,000。我发现另一个有关这种确切情况的StackOverflow问题，显然有两种解决方法。我指的StackOverflow答案在这里：https://stackoverflow.com/a/3488957/1920035
