c# - 列出所有 Active Directory 组

Question

以下代码列出了一些（但不是全部）Active Directory 组。为什么？

我正在尝试列出所有安全组、通讯组、计算机组等。我指定错误了objectClass吗？

private static void ListGroups()
{
    DirectoryEntry objADAM = default(DirectoryEntry);
    DirectoryEntry objGroupEntry = default(DirectoryEntry);
    DirectorySearcher objSearchADAM = default(DirectorySearcher);
    SearchResultCollection objSearchResults = default(SearchResultCollection);
    SearchResult myResult=null;

    objADAM = new DirectoryEntry(LDAP);
    objADAM.RefreshCache();
    objSearchADAM = new DirectorySearcher(objADAM);
    objSearchADAM.Filter = "(&(objectClass=group))";
    objSearchADAM.SearchScope = SearchScope.Subtree;
    objSearchResults = objSearchADAM.FindAll();

    // Enumerate groups 
    try
    {
        fileGroups.AutoFlush = true;
        if (objSearchResults.Count != 0)
        {
            foreach (SearchResult objResult in objSearchResults)
            {
                myResult = objResult;
                objGroupEntry = objResult.GetDirectoryEntry();
                Console.WriteLine(objGroupEntry.Name);
                fileGroups.WriteLine(objGroupEntry.Name.Substring(3));
            }
        }
        else
        {
            throw new Exception("No groups found");
        }  
    } 
    catch (PrincipalException e)
    {
        fileErrorLog.AutoFlush = true;
        fileErrorLog.WriteLine(e.Message + " " + myResult.Path);
    }
    catch (Exception e)
    {
        throw new Exception(e.Message);
    }
}

如果您使用的是 .NET 3.5 或更高版本，则可以使用 aPrincipalSearcher和“按示例查询”主体进行搜索：

// create your domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// define a "query-by-example" principal - here, we search for a GroupPrincipal 
GroupPrincipal qbeGroup = new GroupPrincipal(ctx);

// create your principal searcher passing in the QBE principal    
PrincipalSearcher srch = new PrincipalSearcher(qbeGroup);

// find all matches
foreach(var found in srch.FindAll())
{
    // do whatever here - "found" is of type "Principal" - it could be user, group, computer.....          
}

如果您还没有 - 绝对阅读 MSDN 文章Managing Directory Security Principals in the .NET Framework 3.5，它很好地展示了如何充分利用System.DirectoryServices.AccountManagement

DirectoryEntry entry = new DirectoryEntry("ldap://ldap.gaurangjadia.com", "scott", "tiger");

DirectorySearcher dSearch = new DirectorySearcher(entry);
dSearch.Filter = "(&(objectClass=group))";
dSearch.SearchScope = SearchScope.Subtree;

SearchResultCollection results = dSearch.FindAll();

for (int i = 0; i < results.Count; i++) {
    DirectoryEntry de = results[i].GetDirectoryEntry();

    //TODO with "de"
}

我试过了，它奏效了

    public ArrayList GetAllGroupNames(string ipAddress, string ouPath)
    {
        DirectorySearcher deSearch = new DirectorySearcher();
        deSearch.SearchRoot = GetRootDirectoryEntry(ipAddress, ouPath);
        deSearch.Filter = "(&(objectClass=group))";
        SearchResultCollection results = deSearch.FindAll();
        if (results.Count > 0)
        {
            ArrayList groupNames = new ArrayList();

            foreach (SearchResult group in results)
            {
                var entry = new DirectoryEntry(group.Path, UserName, Password);
                string shortName = entry.Name.Substring(3, entry.Name.Length - 3);
                groupNames.Add(shortName);
            }

            return groupNames;
        }
        else
        {
            return new ArrayList();
        }
    }

    private DirectoryEntry GetRootDirectoryEntry(string ipAddress, string domainPath, string username, string password)
    {
        var ldapPath = "LDAP://" + ipAddress + "/" + domainPath;
        return new DirectoryEntry(ldapPath, username, password, AuthenticationTypes.Secure);
    }

要检索大于 1000 个项目的一组结果，您必须将 SizeLimit 设置为其默认值（零）并将 PageSize 设置为小于或等于 1000 的值。

objSearchADAM.PageSize = 1000;

您可以通过以下 powershell 获取所有广告组详细信息，如果您想要针对 AD 组的特定名称，请编写过滤器而不是 *
