AuthP Multitenant User Management with Blazor 8

[meliora-solution]

This project aims to establish a unified user identity for multitenant environments across multiple projects. The implementation relies on AuthPermissions.AspNetCore.

• TenantCreate.razor can only be accessed by users who have the TenantCreate permission. Therefore, only two users, namely Super@g1.com and AppAdmin@g1.com, have the authority to create tenants.
• InviteUser.razor and AcceptInvitation.razor in the TenantAdminController. are user interfaces used when the tenant wants users to sign up only by invitation.
• Still working on figuring out the process when a tenant wants users to be able to sign up by themselves.

While not many functions have been created yet, these steps are crucial for implementing multitenancy in IdentityUser.

Thank you @JonPSmith . The library is very useful.

Add Tenant in TenantController

There are some good progress implementing this library for Blazor. But I come across a problem with AuthTenantAdminService.

private readonly IAuthPServiceFactory<ITenantChangeService> _tenantChangeServiceFactory; needs to be registered. In the example3 this registration is done in program.cs

.RegisterTenantChangeService<InvoiceTenantChangeService>()

Problem is I dont use Invoice example, so I can not use this way. For temporary solution, I copy AuthTenantAdminService to local clas and removing all the code with ITenantChangeService

    private readonly IAuthPServiceFactory<ITenantChangeService> _tenantChangeServiceFactory;
   var errorString = await tenantChangeService.CreateNewTenantAsync(newTenantStatus.Result);
   if (errorString != null)
      return status.AddErrorString(this.AlreadyLocalized(), errorString); //we assume the tenantChangeService localized its messages

It works, I can create Tenant (Login As Super@g1.com). But I know this is not a good solution. Is there any other way to register ITenantChangeService.

I solved it. I change Example3.InvoiceDbContext. I remove Invoices and LineInvoice and keep only Companies. I think I need the company table for detail information about the tenant.

I have done all the functions in Example 3. And Now I am trying to understand example 6.

What I don't understand is about sharding hasowndb=true but the database has 2 tenants. the owner of db is big rock. But I can assign another tenant to database two. Why is that ? I thought that if the database has already owned by a tenant then I can not assign to other users ?

Hi @meliora-solution,

There two types of sharding: Hybrid or Sharding-Only - see the Sharding explained document. Both types have there pros and cons as explained in the document.

• Example 6 shows the Hybrid type
• Example 7 shows the Sharding-Only type
