  Hi,

  It seems like you have defined the permission correctly and set it for the menu item. But you also need to grant this permission to your user.

  You can either use a code like this

  var user = await UserManager.GetUserByIdAsync(1);
  await UserManager.SetGrantedPermissionsAsync(user, grantedPermissions)
  

  or you can do it in the Seed method of your dbcontext. You need to insert a record to AbpPermissions table. Second option might be good for granting this permission to admin role or admin user.

  Thank you. This is helpful.

  I see now that I forgot to give the permission to the user.

  Where would I ideally add those 2 lines? in which file? thank you

  var user = await UserManager.GetUserByIdAsync(1); await UserManager.SetGrantedPermissionsAsync(user, grantedPermissions)

  I put the following inside my PermissionChecker.cs file and it worked -

          var user = userManager.GetUserByIdAsync(3).Result;
  
          //Grant user3 subscriber permissions to view dashboard pages
          var permissions = PermissionFinder
              .GetAllPermissions(new SEAAuthorizationProvider())
              .Where(n=>n.Name.ToString()=="Pages.Subscribers")
              .ToList();
  
           userManager.SetGrantedPermissionsAsync(user, permissions);
  

  Also, I had to manually update some tables in the database. I probably have to create some functionality from the client side so assigning roles/permissions can be easier or is there a better way? thanks

  All permissions could be defined in your custom AuthorizationProvider

  public class MyAuthorizationProvider : AuthorizationProvider
      {
          public override void SetPermissions(IPermissionDefinitionContext context)
          {
              SetPagePermissions(context);
  
              SetEntityPermissions(context);
  
              var permission = context.GetPermissionOrNull(PermissionNames.Impersonation.Name);
              if (permission == null)
              {
                  context.CreatePermission(PermissionNames.Impersonation.Name);
              }
          }
    }
  

  Also permissions should be assigned to users or roles, you can do it easely in EF Seeds:

  private Role CreateAdminRole(int? tenantId)
          {
              var adminRole = _context.Roles.Include(e => e.Permissions).FirstOrDefault(e => e.Name == StaticRoleNames.Tenants.Admin && e.TenantId == tenantId);
              if(adminRole == null)
              {
                  adminRole = _context.Roles.Add(new Role(tenantId, StaticRoleNames.Tenants.Admin, StaticRoleNames.Tenants.Admin) { IsStatic = true, IsActive = false });
                  _context.SaveChanges();
              }
  
              // Grant all permissions to admin role
              var permissions = PermissionFinder
                  .GetAllPermissions(new MyAuthorizationProvider())
                  .Where(p => p.MultiTenancySides.HasFlag(tenantId.HasValue?MultiTenancySides.Tenant: MultiTenancySides.Host))
                  .ToList();
  
              var existPermissions = adminRole.Permissions?.ToList() ?? new List<RolePermissionSetting>(0);
              if (existPermissions.Count != permissions.Count)
              {
                  foreach (var permission in permissions)
                  {
                      if (existPermissions.Any(e => e.Name == permission.Name && e.TenantId == tenantId)) continue;
  
                      AddPermissionForRole(adminRole, permission, tenantId);
                  }
                  // remove obsolete permissions
                  foreach (var permission in existPermissions)
                  {
                      if (!permissions.Any(e => e.Name == permission.Name)) {
                          _context.Permissions.Remove(permission);
                      }
                  }
  
                  _context.SaveChanges();
              }
  
              return adminRole;
          }
          private void AddPermissionForRole(Role role, Permission permission, int? tenantId)
          {
              _context.Permissions.Add(
                  new RolePermissionSetting
                  {
                      TenantId = tenantId,
                      Name = permission.Name,
                      IsGranted = true,
                      RoleId = role.Id
                  });
          }
