[英]Active Directory Search not returning all users
I have code to populate a user id dropdown list within a VB.net application. 我有代码来填充VB.net应用程序中的用户ID下拉列表。 Some user names are not being returned. 某些用户名未返回。 I'm getting more than 1000 returned so it does not appear to be the 1000 limit. 我得到的返回数量超过1000,因此它似乎不是1000的限制。 If I add (sAMAccountName=Kry*) to the search filter, then the user (whose name starts with kry) that was not appearing does get returned. 如果我将(sAMAccountName = Kry *)添加到搜索过滤器,则返回未出现的用户(其名称以kry开头)。 Any help on this would be greatly appreciated. 任何帮助,将不胜感激。 Thanks! 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
The DirectorySearcher.SizeLimit property is set to 1,000 by default. 默认情况下, DirectorySearcher.SizeLimit属性设置为1,000。 I found another StackOverflow question regarding this exact situation and apparently there are two workarounds. 我发现了另一个有关此确切情况的StackOverflow问题,显然有两种解决方法。 The StackOverflow answer that I am referring to is here: https://stackoverflow.com/a/3488957/1920035 我要指的StackOverflow答案在这里: https : //stackoverflow.com/a/3488957/1920035
