  • Hi eric. tremblay ,

    We currently don't have any scripting that would enable you to do this. We would just limit what the user can see based on the security configured in Views. If a user doesn't have permissions to certain datasets or views, the control would display "Undefined" or be empty.

    You can get the WindowsUserName of the current logged on user and check if they are member of a specific Active Directory group and set the visibility of certain controls if they are authorized.

    Here's some example code to let you do that:

    using AxiomCore2.Client;
    using AxiomCore2.ControlProperties;
    using AxiomCore2.Controls;
    using AxiomCore2.Data;
    using AxiomCore2.Events;
    using AxiomCore2.Legacy;
    using AxiomCore2.Log;
    using AxiomCore2.Managers;
    using System;
    using System.Collections.Generic;
    using System.IO;
    using System.Linq;
    using System.Collections;
    using System.Drawing;
    using System.DirectoryServices;
    using System.DirectoryServices.AccountManagement;
    
    namespace AxiomScript
    {
        public partial class ScreenScript : IDisposable
        {
            // axiom references
            public ControlApplication Application { get; } = ControlApplication.Instance;
            public ControlFactoryManager ControlFactory { get; } = ControlFactoryManager.Instance;
            public IDataProvider DataProvider { get; } = DataProviderManager.CreateInstance();
            public ILog Log { get; } = ClientLog.UserScript;
            public NavigationManager Navigation { get; } = NavigationManager.Instance;
            public ControlScreen Screen => _screen;
    
            public void OnScreenVisible()
            {
                // get arguments used to create the application
                var args = (AxiomCore2.SerializableSandboxArgs)ClientInfo.Instance.GetType().GetField("_sandboxArgs",System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance).GetValue(ClientInfo.Instance);
    
                // get the WindowsUserName property
                var userName = args.WindowsUserName;
    
                // check if the user is member of a specific Active Directory group
                var authorized = IsUserInGroup(userName, "CanaryAdministrators");
    
                // set the visibility of certain controls if the user is authorized
                SetControlsVisibility(authorized);
    
                Log.Info($"User: {userName} Authorized: {authorized}");
            }
    
            public void OnScreenInvisible()
            {
            }
    
            public void Dispose()
            {
            }
    
            public void SetControlsVisibility(bool authorized){
                Label2.IsVisible = authorized;
                ValueBox2.IsVisible = authorized;
            }
    
            public static bool IsUserInGroup(string userName, string groupName)
            {
                // based on example on stackoverflow https://stackoverflow.com/a/76893395/10188134
                try
                {
                    using (PrincipalContext pc = new PrincipalContext(ContextType.Domain))
                    {
                        var gp = GroupPrincipal.FindByIdentity(pc, groupName);
                        var up = UserPrincipal.FindByIdentity(pc, userName);
    
                        if (gp == null || up == null) {
                            return false;
                        }
    
                        DirectoryEntry user = new DirectoryEntry($"LDAP://{up.DistinguishedName}");
                        DirectorySearcher mySearcher = new DirectorySearcher(user)
                        {
                            SearchScope = SearchScope.Subtree,
                            Filter = $"(memberOf:1.2.840.113556.1.4.1941:={gp.DistinguishedName})"  // takes also subgroups
                        };
    
                        return !(mySearcher.FindOne() == null);
                    }
                }
                catch (Exception)
                {
                    return false;
                }
            }
        }
    }
