列出所有Active Directory组

问题描述

下面code列出了一些，但不是全部，Active Directory组。为什么呢？

我想列出所有安全组，通讯组，计算机组等有我指定了错误的对象类？

任何帮助，极大地AP preciated。

 私有静态无效ListGroups（）
    {
        的DirectoryEntry objADAM =默认（的DirectoryEntry）;
        的DirectoryEntry objGroupEntry =默认（的DirectoryEntry）;
        DirectorySearcher从objSearchADAM =默认（DirectorySearcher从）;
        SearchResultCollection objSearchResults =默认（SearchResultCollection）;
        信息搜索结果myResult中= NULL;

        objADAM =新的DirectoryEntry（LDAP）;
        objADAM.RefreshCache（）;
        objSearchADAM =新DirectorySearcher从（objADAM）;
        objSearchADAM.Filter =（及（objectClass的=基团））;
        objSearchADAM.SearchScope = SearchScope.Subtree;
        objSearchResults = objSearchADAM.FindAll（）;

        //枚举组
        尝试
        {
            fileGroups.AutoFlush = TRUE;
            如果（objSearchResults.Count！= 0）
            {
                的foreach（信息搜索结果objResult在objSearchResults）
                {
                    myResult中= objResult;
                    objGroupEntry = objResult.GetDirectoryEntry（）;
                    Console.WriteLine（objGroupEntry.Name）;
                    fileGroups.WriteLine（objGroupEntry.Name.Substring（3））;
                }
            }
            其他
            {
                抛出新的异常（无群体找到）;
            }
        }
        赶上（PrincipalException E）
        {
            fileErrorLog.AutoFlush = TRUE;
            fileErrorLog.WriteLine（e.Message ++ myResult.Path）;
        }
        赶上（例外五）
        {
            抛出新的异常（e.Message）;
        }
    }
 

解决方案

如果您使用的是.NET 3.5或更高版本，可以使用 PrincipalSearcher 和查询逐例如主要做你的搜索：

  //创建域上下文
PrincipalContext CTX =新PrincipalContext（ContextType.Domain）;

//定义一个查询通过例如委托 - 在这里，我们搜索GroupPrincipal
GroupPrincipal qbeGroup =新GroupPrincipal（CTX）;

//创建你的本金搜索传入QBE校长
PrincipalSearcher SRCH =新PrincipalSearcher（qbeGroup）;

//找到所有匹配
的foreach（VAR在srch.FindAll发现（））
{
    //做任何在这里 - 发现的类型是主 - 它可以是用户，组，计算机.....
}
 

如果您还没有 - 绝对阅读MSDN文章管理目录安全主体在.NET Framework 3.5 这表明很好如何使新功能的最佳使用 System.DirectoryServices.AccountManagement

The following code lists some, but not all, Active Directory Groups. Why?

I am trying to list all security groups, distribution groups, computer groups etc. Have I specified the wrong objectClass?

Any assistance greatly appreciated.

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);
        }
    }

解决方案

If you're on .NET 3.5 or newer, you can use a PrincipalSearcher and a "query-by-example" principal to do your searching:

// 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.....
}

If you haven't already - absolutely read the MSDN article Managing Directory Security Principals in the .NET Framework 3.5 which shows nicely how to make the best use of the new features in System.DirectoryServices.AccountManagement
