我已经检查了this帖子。但它没有回答我的问题。我想获取特定用户所属的所有活动目录组。
我写了以下代码。但我无法继续进行,因为我不知道如何提供过滤器以及如何访问属性。
class Program
{
static void Main(string[] args)
{
DirectoryEntry de = new DirectoryEntry("LDAP://mydomain.com");
DirectorySearcher searcher = new DirectorySearcher(de);
searcher.Filter = "(&(ObjectClass=group))";
searcher.PropertiesToLoad.Add("distinguishedName");
searcher.PropertiesToLoad.Add("sAMAccountName");
searcher.PropertiesToLoad.Add("name");
searcher.PropertiesToLoad.Add("objectSid");
SearchResultCollection results = searcher.FindAll();
int i = 1;
foreach (SearchResult res in results)
{
Console.WriteLine("Result" + Convert.ToString(i++));
DisplayProperties("distinguishedName", res);
DisplayProperties("sAMAccouontName", res);
DisplayProperties("name", res);
DisplayProperties("objectSid", res);
Console.WriteLine();
}
Console.ReadKey();
}
private static void DisplayProperties(string property, SearchResult res)
{
Console.WriteLine("\t" + property);
ResultPropertyValueCollection col = res.Properties[property];
foreach (object o in col)
{
Console.WriteLine("\t\t" + o.ToString());
}
}
}
有什么想法吗?

您应该使用System.DirectoryServices.AccountManagement。这更容易。这是一个很好的代码项目article,为您提供此DLL中所有类的概述。
正如您所指出的,您当前的方法没有找到主要群体。实际上,它比你想象的要糟糕得多。还有一些案例不起作用,例如来自另一个域的域本地组。您可以查看here了解详细信息。以下是切换到使用System.DirectoryServices.AccountManagement时代码的样子。以下代码可以找到此用户分配给的直接组,其中包括主要组。
UserPrincipal user = UserPrincipal.FindByIdentity(new PrincipalContext (ContextType.Domain, "mydomain.com"), IdentityType.SamAccountName, "username");
foreach (GroupPrincipal group in user.GetGroups())
{
Console.Out.WriteLine(group);
}

只需查询“memberOf”属性并迭代返回,例如:
search.PropertiesToLoad.Add("memberOf");
StringBuilder groupNames = new StringBuilder(); //stuff them in | delimited
SearchResult result = search.FindOne();
int propertyCount = result.Properties["memberOf"].Count;
String dn;
int equalsIndex, commaIndex;
for (int propertyCounter = 0; propertyCounter < propertyCount;
propertyCounter++)
{
dn = (String)result.Properties["memberOf"][propertyCounter];
equalsIndex = dn.IndexOf("=", 1);
commaIndex = dn.IndexOf(",", 1);
if (-1 == equalsIndex)
{
return null;
}
groupNames.Append(dn.Substring((equalsIndex + 1),
(commaIndex - equalsIndex) - 1));
groupNames.Append("|");
}
return groupNames.ToString();
这只是将组名称填入groupNames字符串,管道分隔,但是当你旋转时,你可以随心所欲地做任何事情

使用tokenGroups:
DirectorySearcher ds = new DirectorySearcher();
ds.Filter = String.Format("(&(objectClass=user)(sAMAccountName={0}))", username);
SearchResult sr = ds.FindOne();
DirectoryEntry user = sr.GetDirectoryEntry();
user.RefreshCache(new string[] { "tokenGroups" });
for (int i = 0; i < user.Properties["tokenGroups"].Count; i++) {
SecurityIdentifier sid = new SecurityIdentifier((byte[]) user.Properties["tokenGroups"][i], 0);
NTAccount nt = (NTAccount)sid.Translate(typeof(NTAccount));
//do something with the SID or name (nt.Value)
}
注意:这只会获得安全组

此代码的工作速度更快(比我以前的版本快两倍):
public List<String> GetUserGroups(WindowsIdentity identity)
{
List<String> groups = new List<String>();
String userName = identity.Name;
int pos = userName.IndexOf(@"\");
if (pos > 0) userName = userName.Substring(pos + 1);
PrincipalContext domain = new PrincipalContext(ContextType.Domain, "riomc.com");
UserPrincipal user = UserPrincipal.FindByIdentity(domain, IdentityType.SamAccountName, userName); // NGeodakov
DirectoryEntry de = new DirectoryEntry("LDAP://RIOMC.com");
DirectorySearcher search = new DirectorySearcher(de);
search.Filter = "(&(objectClass=group)(member=" + user.DistinguishedName + "))";
search.PropertiesToLoad.Add("cn");
search.PropertiesToLoad.Add("samaccountname");
search.PropertiesToLoad.Add("memberOf");
SearchResultCollection results = search.FindAll();
foreach (SearchResult sr in results)
{
GetUserGroupsRecursive(groups, sr, de);
}
return groups;
}
public void GetUserGroupsRecursive(List<String> groups, SearchResult sr, DirectoryEntry de)
{
if (sr == null) return;
String group = (String)sr.Properties["cn"][0];
if (String.IsNullOrEmpty(group))
{
group = (String)sr.Properties["samaccountname"][0];
}
if (!groups.Contains(group))
{
groups.Add(group);
}
DirectorySearcher search;
SearchResult sr1;
String name;
int equalsIndex, commaIndex;
foreach (String dn in sr.Properties["memberof"])
{
equalsIndex = dn.IndexOf("=", 1);
if (equalsIndex > 0)
{
commaIndex = dn.IndexOf(",", equalsIndex + 1);
name = dn.Substring(equalsIndex + 1, commaIndex - equalsIndex - 1);
search = new DirectorySearcher(de);
search.Filter = "(&(objectClass=group)(|(cn=" + name + ")(samaccountname=" + name + ")))";
search.PropertiesToLoad.Add("cn");

以下示例来自代码项目文章(Almost) Everything In Active Directory via C#:
// userDn is a Distinguished Name such as:
// "LDAP://CN=Joe Smith,OU=Sales,OU=domain,OU=com"
public ArrayList Groups(string userDn, bool recursive)
{
ArrayList groupMemberships = new ArrayList();
return AttributeValuesMultiString("memberOf", userDn,
groupMemberships, recursive);
}
public ArrayList AttributeValuesMultiString(string attributeName,
string objectDn, ArrayList valuesCollection, bool recursive)
{
DirectoryEntry ent = new DirectoryEntry(objectDn);
PropertyValueCollection ValueCollection = ent.Properties[attributeName];
IEnumerator en = ValueCollection.GetEnumerator();
while (en.MoveNext())
{
if (en.Current != null)
{
if (!valuesCollection.Contains(en.Current.ToString()))
{
valuesCollection.Add(en.Current.ToString());
if (recursive)
{
AttributeValuesMultiString(attributeName, "LDAP://" +
en.Current.ToString(), valuesCollection, true);
}
}
}
}
ent.Close();
ent.Dispose();
return valuesCollection;
}
只需使用Distinguished Name为用户调用 Groups 方法,然后传入bool标志以指示是否要在生成的ArrayList中包含嵌套/子组成员身份:< / p>
ArrayList groups = Groups("LDAP://CN=Joe Smith,OU=Sales,OU=domain,OU=com", true);
foreach (string groupName in groups)
{
Console.WriteLine(groupName);
}
如果您需要在.NET中进行任何严格级别的Active Directory编程,我强烈建议使用书签和放大器。回顾我上面提到的Code Project文章。

这是我列出特定专有名称的所有组(直接和间接)的方式:
字符串1.2.840.113556.1.4.1941指定LDAP_MATCHING_RULE_IN_CHAIN。
此规则仅限于适用于DN的过滤器。这是一个特殊的“扩展”匹配运算符,它将对象中的祖先链一直走到根,直到找到匹配项。
此方法比我测试中的UserPrincipal.GetGroups()方法快25倍。
注意:此或GetGroups()方法未返回主组(通常是域用户)。为了获得主要组名称,我已经确认this method可以使用。
此外,我发现此list of LDAP过滤器非常有用。
private IEnumerable<string> GetGroupsForDistinguishedName(DirectoryEntry domainDirectoryEntry, string distinguishedName)
{
var groups = new List<string>();
if (!string.IsNullOrEmpty(distinguishedName))
{
var getGroupsFilterForDn = $"(&(objectCategory=group)(member:1.2.840.113556.1.4.1941:={distinguishedName})))";
using (var dirSearch = CreateDirectorySearcher(domainDirectoryEntry, getGroupsFilterForDn))
{
dirSearch.PropertiesToLoad.Add("name");
using (var results = dirSearch.FindAll())
{
foreach (SearchResult result in results)
{
if (result.Properties.Contains("name"))
groups.Add((string)result.Properties["name"][0]);
}

commaIndex = dn1.IndexOf(",", equalsIndex + 1);

我想说Microsoft LDAP有一些特殊的方法来递归搜索用户的所有成员身份。
您可以为“成员”属性指定的匹配规则。特别是,对“成员”属性使用Microsoft独占LDAP_MATCHING_RULE_IN_CHAIN规则可以进行递归/嵌套成员资格搜索。在成员属性之后添加规则时,将使用该规则。例如(成员:1.2.840.113556.1.4.1941:= XXXXX)
对于与帐户相同的域,筛选器可以使用
使用此知识,您可以LDAP查询那些难以获得的成员资格,例如某个帐户所属的“本地域”组,但是除非您查看该组的成员,否则您将不知道该用户是否成员。
//Get Direct+Indirect Memberships of User (where SID is XXXXXX)
string str = "(& (objectCategory=group)(member:1.2.840.113556.1.4.1941:=<SID=XXXXXX>) )";
//Get Direct+Indirect **Domain Local** Memberships of User (where SID is XXXXXX)
string str2 = "(& (objectCategory=group)(|(groupType=-2147483644)(groupType=4))(member:1.2.840.113556.1.4.1941:=<SID=XXXXXX>) )";
//TAA DAA
在替换您要检索其所有组成员身份的用户的SID之后,可以随意尝试这些LDAP查询。我认为这与PowerShell Command Get-ADPrincipalGroupMembership在幕后使用的查询是相同的查询。该命令指出“如果要搜索另一个域中的本地组,请使用ResourceContextServer参数指定另一个域中的备用服务器。”
如果您对C#和Active Directory足够熟悉,那么您应该知道如何使用提供的LDAP查询执行LDAP搜索。

如果您的LDAP连接具有用于连接到Active Directory的用户名和密码,则以下是我用于正确连接的代码:
using System.DirectoryServices.AccountManagement;
// ...
// Connection information
var connectionString = "LDAP://domain.com/DC=domain,DC=com";
var connectionUsername = "your_ad_username";
var connectionPassword = "your_ad_password";
// Get groups for this user
var username = "myusername";
// Split the LDAP Uri
var uri = new Uri(connectionString);
var host = uri.Host;
var container = uri.Segments.Count() >=1 ? uri.Segments[1] : "";
// Create context to connect to AD
var princContext = new PrincipalContext(ContextType.Domain, host, container, connectionUsername, connectionPassword);
// Get User
UserPrincipal user = UserPrincipal.FindByIdentity(princContext, IdentityType.SamAccountName, username);
// Browse user's groups
foreach (GroupPrincipal group in user.GetGroups())
