  but I need to be able to impersonate a tenant user from the host.

  This is not supported by default, can you share your code?

  So the function impersonate in ImpersonationService that have tenantid and userid as parameters - this does not work?

  I knew how to do this in Identity Server - but have no reference for Openiddict - do have no code for now! Just trying to use the impersonate function. And I can see that the call is made and that the payload is correct when looking at ImpersonateUser or ImpersonateTenant. But the server code somehow does not work correctly.

  I have now solved this by doing an override of the existing functionality. Providing code here for others reference:

  1. Create ExtendedImpersonationExtensionGrant.cs in HttpApi.Host

  using Microsoft.AspNetCore.Mvc;
  using Microsoft.Extensions.DependencyInjection;
  using System;
  using System.Security.Claims;
  using System.Threading.Tasks;
  using Volo.Abp.Account.Web.ExtensionGrants;
  using Volo.Abp.Data;
  using Volo.Abp.DependencyInjection;
  using Volo.Abp.Identity;
  using Volo.Abp.MultiTenancy;
  using Volo.Abp.OpenIddict.ExtensionGrantTypes;
  
  namespace xxx.xxxxxx
  {
      public class ExtendedImpersonationExtensionGrant : ImpersonationExtensionGrant
      {
          protected IDataFilter _dataFilter { get; set; }
  
          public override Task<IActionResult> HandleAsync(ExtensionGrantContext context)
          {
              _dataFilter = ServiceProviderServiceExtensions.GetRequiredService<IDataFilter>(context.HttpContext.RequestServices);
  
              return base.HandleAsync(context);
          }
  
          protected async override Task<IActionResult> ImpersonateUserAsync(ExtensionGrantContext context, ClaimsPrincipal principal, Guid? tenantId, Guid userId)
          {
              if (!tenantId.HasValue && !this.currentTenant.IsAvailable)
              {
                  IdentityUser foundUser = null;
  
                  using (_dataFilter.Disable<IMultiTenant>())
                  {
                      // host user
                      foundUser = await this.userManager.FindByIdAsync(userId.ToString());
                  }
  
                  if (foundUser != null) // impersonate directly into user in tenant!
                  {
                      return await base.ImpersonateUserAsync(context, principal, foundUser.TenantId, foundUser.Id);
                  }
              }
  
              return await base.ImpersonateUserAsync(context, principal, tenantId, userId);
          }
  
          protected async override Task<IActionResult> BackToImpersonatorAsync(ExtensionGrantContext context, ClaimsPrincipal principal, Guid? tenantId, Guid userId)
          {
              IdentityUser foundUser = null;
  
              using (_dataFilter.Disable<IMultiTenant>())
              {
                  // host user
                  foundUser = await this.userManager.FindByIdAsync(userId.ToString());
              }
  
              if (foundUser != null && !foundUser.TenantId.HasValue) // Possible to revert back to host user
              {
                  return await base.BackToImpersonatorAsync(context, principal, foundUser.TenantId, foundUser.Id);
              }
              
              return await base.BackToImpersonatorAsync(context, principal, tenantId, userId);
          }
      }
  }
  
  

  2. in HttpApi.HostModule.cs under ConfigureServices(ServiceConfigurationContext context) function add the following:

  this.Configure<AbpOpenIddictExtensionGrantsOptions>((Action<AbpOpenIddictExtensionGrantsOptions>)(options =>
  {
      options.Grants.Remove("Impersonation");
      options.Grants.Add("Impersonation", (IExtensionGrant)new ExtendedImpersonationExtensionGrant());
  }));
  

  Then it works calling the following in Angular - and you can log in to a user under a tenent directly from a host and back again using standard functions:

  this.impersonationService.impersonateUser(entity.id).subscribe((result) => {
    this.toaster.success('::Logged in - please wait');
  })
