从Active Directory检索OU

我正在尝试从活动目录中获取OU的列表。不幸的是,即使我知道“myApp”域组件中有2个OU,我的搜索也总是没有任何结果。

using (var entry = new DirectoryEntry("LDAP://myServer:1111/DC=myApp,DC=myDomain,DC=com", Username, Password)) {
    using (var searcher = new DirectorySearcher()) {
        searcher.SearchRoot = entry;
        searcher.Filter = "(objectCategory=Organizational-Unit)";
        searcher.PropertiesToLoad.Add("name");

        //foo never gets results.  :(
        var foo = searcher.FindAll();
    }
}

我尝试按照之前的StackOverflow question中的代码进行操作,但是没有运气。

我使用这样的东西。它使用路径检索字典名称中的所有OU,只需正确更改SearchScope。

public Dictionary<string, string> GetOUInfo(SearchScope eSearchScope)
    {
        Dictionary<string, string> retValues = new Dictionary<string, string>();

        try
        {
            DirectoryEntry oDirectoryEntry = new DirectoryEntry("LDAP://myServer:1111/DC=myApp,DC=myDomain,DC=com", Username, Password);
            DirectorySearcher oDirectorySearcher = new DirectorySearcher(oDirectoryEntry,
                "(objectCategory=organizationalUnit)", null, eSearchScope);

            SearchResultCollection oSearchResultCollection = oDirectorySearcher.FindAll();
            foreach (SearchResult item in oSearchResultCollection)
            {
                string name = item.Properties["name"][0].ToString();
                string path = item.GetDirectoryEntry().Path;
                retValues.Add(path, name);
            }
        }
        catch (Exception ex)
        {
        }

        return retValues;
    }

1)您确定基本搜索"DC=myApp,DC=myDomain,DC=com"吗? "myApp"是域组件吗?

2)您可以尝试指定搜索范围吗?

searcher.SearchScope = SearchScope.Subtree;

3)"(objectCategory=Organizational-Unit)"是Active-Directory理解的快捷方式,但实际上objectCategory属性是专有名称(DN),OU的实际值是:CN=Organizational-Unit,CN=Schema,CN=Configuration,domain root DN

您可以尝试使用这种搜索OU更常见的过滤器"(objectClas=Organizational-Unit)"吗?


在命令行上可以试试吗?

C:\temp>ldifde -f c:\temp\out.txt -d "DC=myApp,DC=myDomain,DC=com" -r "(objectClass=organizationalUnit)"

使用此功能

PrincipalContext yourOU = new PrincipalContext(ContextType.Domain, "mycompany.com", "OU=Marketing,OU=Corporate,DC=mycompany,DC=com");
GroupPrincipal findAllGroups = new GroupPrincipal(yourOU, "*");
PrincipalSearcher ps = new PrincipalSearcher(findAllGroups);
foreach (var group in ps.FindAll())
{
Console.WriteLine(group.DistinguishedName);
}
