Question

我需要一种方法来查看用户是否是我的.Net 3.5 asp.net c＃应用程序中的活动目录组的一部分。

我正在使用msdn的标准ldap身份验证示例，但我真的没有看到如何检查组。

Answer 1

使用3.5和System.DirectoryServices.AccountManagement这有点清洁：

public List<string> GetGroupNames(string userName)
{
  var pc = new PrincipalContext(ContextType.Domain);
  var src = UserPrincipal.FindByIdentity(pc, userName).GetGroups(pc);
  var result = new List<string>();
  src.ToList().ForEach(sr => result.Add(sr.SamAccountName));
  return result;
}

Answer 2

Nick Craver的解决方案在.NET 4.0中对我不起作用。我收到有关卸载的AppDomain的错误。我没有使用它，而是使用了这个（我们只有一个域）。这将检查组的组以及直接组成员身份。

using System.DirectoryServices.AccountManagement;
using System.Linq;

...

using (var ctx = new PrincipalContext(ContextType.Domain, yourDomain)) {
    using (var grp = GroupPrincipal.FindByIdentity(ctx, IdentityType.Name, yourGroup)) {
        bool isInRole = grp != null && 
            grp
            .GetMembers(true)
            .Any(m => m.SamAccountName == me.Identity.Name.Replace(yourDomain + "\\", ""));
    }
}

Answer 3

以下代码适用于.net 4.0

private static string[] GetGroupNames(string userName)
{
    List<string> result = new List<string>();

    using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, "YOURDOMAIN"))
    {
        using (PrincipalSearchResult<Principal> src = UserPrincipal.FindByIdentity(pc, userName).GetGroups(pc))
        {
            src.ToList().ForEach(sr => result.Add(sr.SamAccountName));
        }
    }

    return result.ToArray();
}

Answer 4

最简单的解决方案

PrincipalContext pc = new PrincipalContext((Environment.UserDomainName == Environment.MachineName ? ContextType.Machine : ContextType.Domain), Environment.UserDomainName);

GroupPrincipal gp = GroupPrincipal.FindByIdentity(pc, "{GroupName}");
UserPrincipal up = UserPrincipal.FindByIdentity(pc, Environment.UserName);
up.IsMemberOf(gp);

Answer 5

如果您尝试确定Windows身份验证的当前用户是否处于特定角色，则此方法可能会有所帮助。

public static bool CurrentUserIsInRole(string role)
{
    try
    {
        return System.Web.HttpContext.Current.Request
                    .LogonUserIdentity
                    .Groups
                    .Any(x => x.Translate(typeof(NTAccount)).ToString() == role);
        }
        catch (Exception) { return false; }
    }

Answer 6

如果用户在AD组中，则取决于您的意思。在AD中，组可以是安全组或通讯组。即使对于安全组，也取决于是否需要将“域用户”或“用户”等组包含在成员资格检查中。

IsUserInSecurityGroup仅检查安全组，并且将适用于主要组类别的组，如“域用户”和“用户”，而不是分发组。它还将解决嵌套组的问题。 IsUserInAllGroup还将检查通讯组，但我不确定您是否会遇到权限问题。如果您这样做，请使用WAAG（See MSDN）

中的服务帐户

我没有使用UserPrincipal.GetAuthorizedGroups（）的原因是因为它有很多问题，例如要求呼叫帐户在WAAG中并且要求SidHistory中没有条目（See David Thomas' comment）

public bool IsUserInSecurityGroup(string user, string group)
    {
        return IsUserInGroup(user, group, "tokenGroups");
    }
    public bool IsUserInAllGroup(string user, string group)
    {
        return IsUserInGroup(user, group, "tokenGroupsGlobalAndUniversal");
    }

    private bool IsUserInGroup(string user, string group, string groupType)
    {
        var userGroups = GetUserGroupIds(user, groupType);
        var groupTokens = ParseDomainQualifiedName(group, "group");
        using (var groupContext = new PrincipalContext(ContextType.Domain, groupTokens[0]))
        {
            using (var identity = GroupPrincipal.FindByIdentity(groupContext, IdentityType.SamAccountName, groupTokens[1]))
            {
                if (identity == null)
                    return false;

                return userGroups.Contains(identity.Sid);
            }
        }
    }
    private List<SecurityIdentifier> GetUserGroupIds(string user, string groupType)
    {
        var userTokens = ParseDomainQualifiedName(user, "user");
        using (var userContext = new PrincipalContext(ContextType.Domain, userTokens[0]))
        {
            using (var identity = UserPrincipal.FindByIdentity(userContext, IdentityType.SamAccountName, userTokens[1]))
            {
                if (identity == null)
                    return new List<SecurityIdentifier>();

                var userEntry = identity.GetUnderlyingObject() as DirectoryEntry;
                userEntry.RefreshCache(new[] { groupType });
                return (from byte[] sid in userEntry.Properties[groupType]
                        select new SecurityIdentifier(sid, 0)).ToList();
            }
        }
    }
    private static string[] ParseDomainQualifiedName(string name, string parameterName)
    {
        var groupTokens = name.Split(new[] {"\\"}, StringSplitOptions.RemoveEmptyEntries);
        if (groupTokens.Length < 2)
            throw new ArgumentException(Resources.Exception_NameNotDomainQualified + name, parameterName);
        return groupTokens;
    }

Answer 7

这是我的2美分。

    static void CheckUserGroup(string userName, string userGroup)
    {
        var wi = new WindowsIdentity(userName);
        var wp = new WindowsPrincipal(wi);

        bool inRole = wp.IsInRole(userGroup);

        Console.WriteLine("User {0} {1} member of {2} AD group", userName, inRole ? "is" : "is not", userGroup);
    }

Answer 8

这似乎更简单：

public bool IsInRole(string groupname)
{
    var myIdentity = WindowsIdentity.GetCurrent();
    if (myIdentity == null) return false;

    var myPrincipal = new WindowsPrincipal(myIdentity);
    var result = myPrincipal.IsInRole(groupname);

    return result;
}

How to write LDAP query to test if user is member of a group?

Answer 10

您可以尝试以下代码：

public bool Check_If_Member_Of_AD_Group(string username, string grouptoCheck, string domain, string ADlogin, string ADpassword)
{
    
     try {
        
        string EntryString = null;
        EntryString = "LDAP://" + domain;
        
        DirectoryEntry myDE = default(DirectoryEntry);
        
        grouptoCheck = grouptoCheck.ToLower();
        
        
        myDE = new DirectoryEntry(EntryString, ADlogin, ADpassword);
        
        DirectorySearcher myDirectorySearcher = new DirectorySearcher(myDE);
        
        myDirectorySearcher.Filter = "sAMAccountName=" + username;
        
        myDirectorySearcher.PropertiesToLoad.Add("MemberOf");
        
        SearchResult myresult = myDirectorySearcher.FindOne();
        
        int NumberOfGroups = 0;
        
        NumberOfGroups = myresult.Properties["memberOf"].Count - 1;
        
        string tempString = null;
        
        while ((NumberOfGroups >= 0)) {
            
            tempString = myresult.Properties["MemberOf"].Item[NumberOfGroups];
            tempString = tempString.Substring(0, tempString.IndexOf(",", 0));
            
            tempString = tempString.Replace("CN=", "");
            
            tempString = tempString.ToLower();
            tempString = tempString.Trim();
            
            if ((grouptoCheck == tempString)) {
                
                    
                return true;
            }
            
                
            NumberOfGroups = NumberOfGroups - 1;
        }
        
            
        return false;
    }
    catch (Exception ex) {
        
        System.Diagnostics.Debugger.Break();
    }
    //HttpContext.Current.Response.Write("Error: <br><br>" & ex.ToString)
}

布兰登约翰逊，喜欢它，我用你所拥有的，但做了以下改变：

private static string[] GetGroupNames(string domainName, string userName)
{
    List<string> result = new List<string>();

    using (PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, domainName))
    {
        using (PrincipalSearchResult<Principal> src = UserPrincipal.FindByIdentity(principalContext, userName).GetGroups(principalContext))
        {
            src.ToList().ForEach(sr => result.Add(sr.SamAccountName));
        }
    }

    return result.ToArray();
}

Answer 14

如果要检查用户组成员身份，包括间接链接到用户父组的嵌套组，您可以尝试使用＆＃34; tokenGroups＆＃34;属性如下：

Using System.DirectoryServices

 public static bool IsMemberOfGroupsToCheck(string DomainServer, string LoginID, string LoginPassword)
        {
            string UserDN = "CN=John.Doe-A,OU=Administration Accounts,OU=User Directory,DC=ABC,DC=com"
            string ADGroupsDNToCheck = "CN=ADGroupTocheck,OU=Administration Groups,OU=Group Directory,DC=ABC,DC=com";

            byte[] sid, parentSID;
            bool check = false;
            DirectoryEntry parentEntry;
            DirectoryEntry basechildEntry;
            string octetSID;

                basechildEntry = new DirectoryEntry("LDAP://" + DomainServer + "/" + UserDN, LoginID, LoginPassword);
                basechildEntry.RefreshCache(new String[] { "tokenGroups" });

                parentEntry = new DirectoryEntry("LDAP://" + DomainServer + "/" + ADGroupsDNToCheck, LoginID, LoginPassword);
                parentSID = (byte[])parentEntry.Properties["objectSID"].Value;
                octetSID = ConvertToOctetString(parentSID, false, false);

                foreach(Object GroupSid in basechildEntry.Properties["tokenGroups"])
                {
                    sid = (byte[])GroupSid;
                    if (ConvertToOctetString(sid,false,false) == octetSID)
                    {
                        check = true;
                        break;
                    }
                }

                basechildEntry.Dispose();
                parentEntry.Dispose();

                return check;
        }

Answer 15

这应该在.NET 3.5+中起作用

// using System.DirectoryServices.AccountManagement;
public static bool IsUserMemberOfGroup(string username, string group)
{
    using (var ctx = new PrincipalContext(ContextType.Domain))
    using (var usr = UserPrincipal.FindByIdentity(ctx, username))
        return usr.IsMemberOf(ctx, IdentityType.Name, group);
}

这与这里的许多答案类似，但这是
