We are currently working on a project using the ABP framework and would like to implement a multi-tenancy feature where a single user instance can be associated with multiple tenants.
Currently, when we attempt to create a user under a different tenant using an email address that already exists in another tenant, the framework creates a new user instance with the same email address for this tenant. However, our requirement is to allow the same user instance to belong to multiple tenants. That is one user to many tenants collaboration.
We noticed that ABP.io's web application has implemented such a feature. For instance, a single user can belong to multiple organizations (tenants) while maintaining the same user identity and credentials.

Hi,
We noticed that ABP.io's web application has implemented such a feature. For instance, a single user can belong to multiple organizations (tenants) while maintaining the same user identity and credentials.
It's not like that, users only belong to multiple organizations but under the same tenant.
Currently, when we attempt to create a user under a different tenant using an email address that already exists in another tenant, the framework creates a new user instance with the same email address for this tenant. However, our requirement is to allow the same user instance to belong to multiple tenants. That is one user to many tenants collaboration.
You can consider adding a page to show the tenant list and change the current tenant.
For example, add a new cookie tenant resolve contributor and add it to the top of resolvers
public class MyCookieTenantResolveContributor : HttpTenantResolveContributorBase { public const string ContributorName = "Cookie"; public override string Name => ContributorName; protected override Task<string?> GetTenantIdOrNameFromHttpContextOrNullAsync(ITenantResolveContext context, HttpContext httpContext) { return Task.FromResult(httpContext.Request.Cookies["my_tenant_key"]); } }public class SwitchTenantModel .... { public ... OnPostAsync() { // set tenant to cookie and refresh the page } }https://abp.io/docs/latest/framework/architecture/multi-tenancy#determining-the-current-tenant

Hi,

It's not possible. tenant data is isolated.
we can list all the tenants for the user and switch between them
ABP determines the current tenant with the current user's tenant id as the first option. So I suggest you add a custom cookie tenant resolver as a first option, in this way, ABP ignores the current user's tenant id for the purpose of dynamic tenant switching.

I am reaching out to learn more about the functionality implemented on your platform, ABP.io, where a single user can be associated with multiple tenants or organizations within the same instance. This feature, as showcased in your platform, provides a seamless experience for users managing multiple organizations under one account.
I would like to be the owner of one tenant while simultaneously being a member of another tenant.
I am currently exploring a similar requirement in one of our projects and would greatly appreciate it if you could share insights into how this functionality was achieved. Specifically:
Architecture and Design: How did you design the mapping between a single user and multiple tenants? Are there any specific database structures or entities used to facilitate this?
Authorization and Role Management: How are roles and permissions handled for a user across different tenants? Does your solution support tenant-specific roles for the same user?
Implementation Details: Are there any particular ABP modules or configurations leveraged to achieve this?
