c# - 从事件目录中检索组下的用户列表时出错(C# 中的 System.DirectoryServices.AccountManagement)

Question

我在从事件目录中检索组下的用户时遇到错误。错误描述是{“无法检索有关域的信息 (1355)”}。尝试使用 .Net 4.0 和 .Net 4.5。我收到错误的行已用错误消息进行注释。

public List<DirectoryUser> GetUsersUnderGroup(string groupName)
    {
        var directoryUserList = new List<DirectoryUser>();
        string directoryServerIp="192.168.1.xxx";
        string ouName="xxxOuName";
        string domainComponents="DC=xxxComopnent1,DC=xxxComponent2";
        string directoryAdminUserId="directoryAdminuser";
        string directoryAdminPassword="directoryAdminPassword";
        using (var principalContext = principalContext = new PrincipalContext(ContextType.Domain, directoryServerIp, string.Format("OU={0},{1}", ouName, domainComponents), directoryAdminUserId, directoryAdminPassword);)
        {
            using (var group = GroupPrincipal.FindByIdentity(principalContext, groupName))
            {
                if (group != null)
                {                       
                    var users = group.GetMembers(true);
                    //Works fine till the above line. variable users is having not null value but
                    //exception while iterating through the loop.Following is the exception
                    //{"Information about the domain could not be retrieved (1355)."}
                    foreach(var user in users)
                    {                            
                        Console.Write(user.DistinguishedName);
                    }
                }
            }
        }
        return directoryUserList;
    }

创建 PrincipalContext 的代码在其他情况下工作正常(例如获取组列表和 OU 等)

本文介绍了您遇到问题的原因和可能的解决方案:link .基本上，如果您不是从域 Controller 所在的计算机运行代码，则必须使用 DirectoryEntry 类。本文应该可以帮助您理解该类:link
