This my code:

        string userName = "";
        string password = "";

        userName = ConfigurationManager.AppSettings["UserName"];
        password = ConfigurationManager.AppSettings["Password"];
        domain = ConfigurationManager.AppSettings["domain"];

        IServiceManagement<IOrganizationService> orgServiceManagement = ServiceConfigurationFactory.CreateManagement<IOrganizationService>(serviceUri);

        if (orgServiceManagement.AuthenticationType == AuthenticationProviderType.Federation)
        {
            // ADFS (IFD) Authentication
            ClientCredentials clientCred = new ClientCredentials();
            clientCred.UserName.UserName = userName;
            clientCred.UserName.Password = password;
            _serviceProxy = new OrganizationServiceProxy(orgServiceManagement, clientCred);
        }
        else if (orgServiceManagement.AuthenticationType == AuthenticationProviderType.OnlineFederation)
        {
            // Online authentication
            AuthenticationCredentials authCredentials = new AuthenticationCredentials();

            authCredentials.ClientCredentials.UserName.UserName = userName;
            authCredentials.ClientCredentials.UserName.Password = password;

            // Error getting here
            AuthenticationCredentials tokenCredentials = orgServiceManagement.Authenticate(authCredentials); 

            _serviceProxy = new OrganizationServiceProxy(orgServiceManagement, tokenCredentials.SecurityTokenResponse);
        }
        else
        {
            // On-Premise, non-IFD authentication
            ClientCredentials credentials = new ClientCredentials();
            credentials.Windows.ClientCredential = new NetworkCredential(userName, password, domain);
            _serviceProxy = new OrganizationServiceProxy(serviceUri, null, credentials, null);
        }

        _serviceProxy.EnableProxyTypes();

    }
    catch (Exception e)

    }

    return (IOrganizationService)_serviceProxy;
}
