Question

起初我认为下面的代码有效，因为如果我将该组作为“IT”，它可以正常运行，因为我的用户名在活动目录中的IT组中。我学到的是，无论我是否在IT组中拥有我的用户名，它总是返回，如果我将其更改为我所在的任何其他组，则返回始终返回false。任何帮助将不胜感激。

    private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
    {
        // tab control security for admin tab
        bool admin = checkGroup("IT");

        if ((admin == true) && (tabControl1.SelectedTab == tpHistory))
        {
            tabControl1.SelectedTab = tpHistory;
        }
        else if ((admin == false) && (tabControl1.SelectedTab == tpHistory))
        {
            tabControl1.SelectedTab = tpRequests;
            MessageBox.Show("Unable to load tab. You have insufficient privileges.",
                "Access Denied", MessageBoxButtons.OK, MessageBoxIcon.Stop);
        }
    }

    // check active directory to see if user is in Marketing department group
    private static bool checkGroup(string group)
    {
        WindowsIdentity identity = WindowsIdentity.GetCurrent();
        WindowsPrincipal principal = new WindowsPrincipal(identity);
        return principal.IsInRole(group);
    }

Answer 1

由于您使用的是.NET 3.5及更高版本，因此您应该查看System.DirectoryServices.AccountManagement（S.DS.AM）命名空间。在这里阅读所有相关内容：

基本上，您可以定义域上下文并轻松在AD中查找用户和/或组：

// set up domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "DOMAINNAME");

// find a user
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, "SomeUserName");

// find the group in question
GroupPrincipal group = GroupPrincipal.FindByIdentity(ctx, "YourGroupNameHere");

if(user != null)
{
   // check if user is member of that group
   if (user.IsMemberOf(group))
   {
     // do something.....
   } 
}

新的S.DS.AM让您可以轻松地与AD中的用户和群组一起玩！

Answer 2

与static void Main()中的Program方法实施的@marc_s示例略有偏差：

DomainCtx = new PrincipalContext( ContextType.Domain , Environment.UserDomainName );
if ( DomainCtx != null ) {
    User = UserPrincipal.FindByIdentity( DomainCtx , Environment.UserName );
}

DomainCtx和User都是在Program

下声明的静态属性

然后在其他形式我只做这样的事情：

if ( Program.User.IsMemberOf(GroupPrincipal.FindByIdentity(Program.DomainCtx, "IT-All") )) {
    //Enable certain Form Buttons and objects for IT Users

}

Answer 3

你不能这样做。您应该查询活动目录。您可以使用AD包装器。查看http://www.codeproject.com/Articles/10301/Wrapper-API-for-using-Microsoft-Active-Directory-S

检查当前用户是否在组中

public bool AuthenticateGroup(string groupfind)
        {
            var p = new Process();
            StringBuilder stringbd = new StringBuilder();
            p.StartInfo.FileName = "cmd.exe";
            p.StartInfo.Arguments = @"/c gpresult /V";
            p.StartInfo.CreateNoWindow = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardInput = false;
            p.StartInfo.UseShellExecute = false;
            p.OutputDataReceived += (a, b) => stringbd.AppendLine(b.Data);
            p.ErrorDataReceived += (a, b) => stringbd.AppendLine(b.Data);
            p.Start();
            p.BeginErrorReadLine();
            p.BeginOutputReadLine();
            p.WaitForExit();
            var textfind = stringbd.ToString();
            int findpoint = textfind.IndexOf("The user is a part of");
            string findgroup = "";
            if (findpoint > 0)
            {
                findgroup = textfind.Substring(findpoint, textfind.Length - findpoint);
            }

            return findgroup.Split('\n').ToList().Any(r=>r.Trim().ToLower()==groupfind.Trim().ToLower());
        }

如何检查用户是否属于AD组？
