使用VB.NET，如何使用Active Directory将sid转换为组名？

示例：我需要获得“group_test”而不是“S-1-5-32-544”

我正在使用的代码是：

Public ReadOnly Property Groups As IdentityReferenceCollection
    Get

        Dim irc As IdentityReferenceCollection
        Dim ir As IdentityReference
        irc = WindowsIdentity.GetCurrent().Groups
        Dim strGroupName As String

        For Each ir In irc
            Dim mktGroup As IdentityReference = ir.Translate(GetType(NTAccount))
            MsgBox(mktGroup.Value)
            Debug.WriteLine(mktGroup.Value)
            strGroupName = mktGroup.Value.ToString

        Next

        Return irc

    End Get
End Property

或类似的东西？

        currentUser = WindowsIdentity.GetCurrent()

        For Each refGroup As IdentityReference In currentUser.Groups

            Dim acc As NTAccount = TryCast(refGroup.Translate(GetType(NTAccount)), NTAccount)
            If AdminGroupName = acc.Value Then
                ret = "999"
            End If
            If UsersGroupName = acc.Value Then
                ret = "1"
            End If

你将如何适应这段代码？（如果用户在xx组中，请在下拉列表中显示xx组）

        For Each UserGroup In WindowsIdentity.GetCurrent().Groups
            If mktGroup.Value = "BIG" Then
                Dim Company = ac1.Cast(Of MarketingCompany).Where(Function(ac) ac.MarketingCompanyShort = "BIG").FirstOrDefault
                If Company IsNot Nothing Then
                    marketingCo.Items.Add(String.Format("{0} | {1}", Company.MarketingCompanyShort, Company.MarketingCompanyName))
                End If
            End If
        Next

Answer 1

C＃中的代码：

    public static string GetGroupNameBySid(string sid)
    {
        PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
        GroupPrincipal group = GroupPrincipal.FindByIdentity(ctx, IdentityType.Sid, sid);
        return group.SamAccountName;
    }

您必须添加程序集System.DirectoryServices.AccountManagement.dll。如果连接到AD时遇到任何问题，可以尝试在PrincipalContext构造函数中添加AD服务器名称。

以下是如何将SID转换为名称的链接：http://vbdotnet.canbal.com/view.php?sessionid=JEf85K%2B%2BeBj9Pz%2BWz9hJJicW%2FYEPtADXfcpYCovZ7js%3D

基本上，您将获得一个DirectoryEntry对象，然后您可以使用该对象来获取名称。但是，如果您正在寻找我认为更容易实现此目的的方法，那么只需占用当前用户并在AD中查找其组成员身份。以下是如何执行该操作的示例（您需要更大的文章来实际完成您的任务，但此代码是您问题的具体答案）：http://www.codeproject.com/KB/system/everythingInAD.aspx#39

很抱歉代码是在C＃中。但是，您应该能够使用转换器将其转换为VB.NET而不会出现问题。

在C＃

中从ASP.NET获取登录用户的用户组成员资格

public ArrayList Groups()
{
    ArrayList groups = new ArrayList();

    foreach (System.Security.Principal.IdentityReference group in
            System.Web.HttpContext.Current.Request.LogonUserIdentity.Groups)
    {
        groups.Add(group.Translate(typeof
        (System.Security.Principal.NTAccount)).ToString());
    }

    return groups;
 }

使用Developer Fusion's Converter Tool从VB.NET中的ASP.NET获取登录用户的用户组成员资格：

    Public Function Groups() As ArrayList
        Dim groups__1 As New ArrayList()

        For Each group As System.Security.Principal.IdentityReference In                 System.Web.HttpContext.Current.Request.LogonUserIdentity.Groups

               groups__1.Add(group.Translate(GetType(System.Security.Principal.NTAccount)).ToString())
        Next

    Return groups__1
    End Function

这是一个用C＃编写的简单方法，我认为这并不难以适应：

  /* Retreiving object from SID
  */
  string SidLDAPURLForm = "LDAP://WM2008R2ENT:389/<SID={0}>";
  System.Security.Principal.SecurityIdentifier sidToFind = new System.Security.Principal.SecurityIdentifier("S-1-5-21-3115856885-816991240-3296679909-1106");

  DirectoryEntry userEntry = new DirectoryEntry(string.Format(SidLDAPURLForm, sidToFind.Value));

  string name = userEntry.Properties["cn"].Value.ToString();

这要归功于VB .NET，感谢REFLECTOR

Dim SidLDAPURLForm As String = "LDAP://WM2008R2ENT:389/<SID={0}>"
Dim sidToFind As New SecurityIdentifier("S-1-5-21-3115856885-816991240-3296679909-1106")
Dim userEntry As New DirectoryEntry(String.Format(SidLDAPURLForm, sidToFind.Value))
Dim name As String = userEntry.Properties.Item("cn").Value.ToString

---- EDITED ----- 所以这就是你想要的，但它与之前由@BiggsTRC

给出的相同

Private Shared Sub Main(args As String())
    Dim currentUser As WindowsIdentity = WindowsIdentity.GetCurrent()

For Each iRef As IdentityReference In currentUser.Groups
        Console.WriteLine(iRef.Translate(GetType(NTAccount)))
    Next
End Sub
