Add/Update TenantId in .Net Core Identity

[kallievz]

Hi All.

Bit of background, we have a couple of users spanning Tenants. They can access data across a couple of tenants, but not all same time.

So, what we are trying to achieve:
Single User in Identity, set up and linked to a Tenant, with specific roles(UserRoles) and Permissions(RoleClaims) .
Now, the user can have the option to "switch" tenant, updating the User table with the new Tenants, and refresh token to apply the relevant claims referreing to the the "new" tenant.

So, in stead of Duplicating User in UserTable, we would like to have the abitity to update TenantId in Identity Table. I tried, but Getting the TenantMismatch , as context is tenant aware, and the user does not currently belong to tenant i want to update. How would you suggest in handling this approach. Setting Up a TenantUser entity, where user is linked, Use the UserRole entity to see which tenant user is linked to?

And how do i override the TenantId already set on an Entity in order to Update the User Table?

Might seems simple, but not really. Any advice would be appreciated.

Kind Regards

Hi, in your case I don't know if MultiTenantIdentityDbContext is the best choice -- the standard IdentityDbContext with an added tenant entity and a many-to-many relationship with user and tenant might be a better design. Then its just a single user entry tied to as many tenants as needed. This means your Identity database is not automatically filtered per-tenant or enforced with mismatch etc. But it might work well for you.

Then you can simply use a session variable to mark the "current" tenant for the user and give them a menu to switch between them.

What do you think?

Thanks for the response. I will try this when i swoop to the access parts again. Playing a bit with Maui Blazor Hybrid with web and a shared RCL.
