获取 Active Directory 中某个组的所有用户

Question

我试图获取 AD 中特定组的所有用户，然后返回映射到我的 Employee 类中的属性的员工列表。我有：

我的过滤器没有产生任何结果 - 应该是什么？

另外，我在这里尝试了第一个解决方案： 特定 Active Directory 通讯组中的用户列表，但我需要诸如移动电话、分机号等详细信息，但使用该方法无法获得这些信息。

public static List<Employee> CreateEmployeeList(string department)
{
    List<Employee> employees = new List<Employee>();
    string filter = string.Format("(&(ObjectClass=person)(memberOf=CN={0},OU=Users & Groups,OU=Blah,DC=Blah,DC=Blah,DC=Blah))", department);

    DirectoryEntry adRoot = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure);
    DirectorySearcher searcher = new DirectorySearcher(adRoot);
    searcher.SearchScope = SearchScope.Subtree;
    searcher.ReferralChasing = ReferralChasingOption.All;
    searcher.Filter = filter;
    SearchResultCollection results = searcher.FindAll();

    foreach (SearchResult user in results)
    {
        // do whatever you need to do with the entry

        if (user != null)
        {
            UserDirectoryEntry = user.GetDirectoryEntry();
            string displayName = GetUserProperty("displayName");
            string firstName = GetUserProperty("givenName");
            string lastName = GetUserProperty("sn");
            string email = GetUserProperty("mail");
            string tel = GetUserProperty("telephonenumber");
            string extension = GetUserProperty("ipphone");
            string mobile = GetUserProperty("mobile");
            string title = GetUserProperty("description");
            employees.Add(new Employee{ FullName = displayName, FirstName = firstName, Surname = lastName, Email = email.ToLower(), Telephone = tel, Extension = extension, Mobile = mobile, JobTitle = title });
        }
    }
    return employees;
}

using (var context = new PrincipalContext(ContextType.Domain, "domainName"))
{
    using (var group = GroupPrincipal.FindByIdentity(context, "groupName"))
    {
        if (group == null)
        {
            MessageBox.Show("Group does not exist");
        }
        else
        {
            var users = group.GetMembers(true);
            foreach (UserPrincipal user in users)
            {
                 //user variable has the details about the user 
            }
        } 
    }
}

这应该返回组中的所有 Active Directory 用户。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.DirectoryServices;

namespace ADQuery
{
    class Program
    {
        static void Main(string[] args)
        {
            GetListOfAdUsersByGroup("domain", "group");
            Console.ReadLine();
        }

        public static void GetListOfAdUsersByGroup(string domainName, string groupName)
        {
            DirectoryEntry entry = new DirectoryEntry("LDAP://DC=" + domainName + ",DC=com");
            DirectorySearcher search = new DirectorySearcher(entry);
            string query = "(&(objectCategory=person)(objectClass=user)(memberOf=*))";
            search.Filter = query;
            search.PropertiesToLoad.Add("memberOf");
            search.PropertiesToLoad.Add("name");

            System.DirectoryServices.SearchResultCollection mySearchResultColl = search.FindAll();
            Console.WriteLine("Members of the {0} Group in the {1} Domain", groupName, domainName);
            foreach (SearchResult result in mySearchResultColl)
            {
                foreach (string prop in result.Properties["memberOf"])
                {
                    if (prop.Contains(groupName))
                    {
                        Console.WriteLine("    " + result.Properties["name"][0].ToString());
                    }
                }
            }
        }
    }
}

祝你好运！

基于 Dalton 的示例，以下是获取组用户名的简洁代码：

static SortedSet<string> GetUsernames(string domainName, string groupName) {
  using (var pc = new PrincipalContext(ContextType.Domain, domainName))
  using (var gp = GroupPrincipal.FindByIdentity(pc, groupName))
    return gp == null ? null : new SortedSet<string>(
      gp.GetMembers(true).Select(u => u.SamAccountName));
}

以下代码将递归搜索嵌套域本地组和/或全局组以查找用户。您可以修改它以查看任何组的顺序以满足您的需要或返回您想要的任何类型的组。

// Set the list to return and get the group we are looking through.
List<UserPrincipal> list = new List<UserPrincipal>();
GroupPrincipal group = GroupPrincipal.FindByIdentity(new PrincipalContext(/* connection info here */), ((groupName.Length > 0) ? groupName : this.Properties.Name));

// For each member of the group add all Users.
foreach (Principal princ in group.Members)
{
    /*
    To change what you are looking for or how you are looking for it, 
    simply change some of the following conditions to match what you want.
    */

    // If this member is a User then add them.
    if (princ.StructuralObjectClass == "user")
    {
        list.Add(UserPrincipal.FindByIdentity(new PrincipalContext(/* connection info here */), princ.Name);
    }

    // If we are looking recursively and this member is a GL_Group then get the Users in it and add them.
    if (recursive && (princ.StructuralObjectClass == "group") && (((GroupPrincipal)princ).GroupScope == GroupScope.Global))
    {
        list.AddRange(this.GetUsers(true, princ.Name));
    }
}
return list;

在这篇文章中我写了一些在 ActiveDirectory 2003 和 2008 R2 中工作的东西。我使用 Microsoft LDAP_MATCHING_RULE_IN_CHAIN。该服务使用DirectoryServices。请小心这段代码，因为存在双重搜索。

但您也可以使用管理 .NET Framework 3.5 中的目录安全主体< /a>.您可以阅读这篇文章。您必须获取 GroupPrincipal 并且您正在寻找 Members 属性。 StackOverflow 中还存在其他条目。
