Sharing Dashboard to Guest user from 2 Tenants

[MosesLim]

I'm currently exploring the risk of using guest user to share my dashboard to multiple users from different AAD.

Tenants/Users:

1. ADX Cluster Tenant
2. External Tenant 1
1. Ext Tenant 1 Guest 1
3. External Tenant 2
1. Ext Tenant 2 Guest 2

Scenario 1:

1. External Tenant 1 Guest 1 aren't able to share the dashboard created by ADX Cluster Tenant as they are only given Viewers.

Scenario 2:

1. Ext Tenant 1 Guest 1 can do the following in sequence.
1. Save as copy for a dashboard that is shared to although with viewer access.
2. Then using the Share --> Manage Permission, it allows to search for Ext Tenant 2 Guest 2 and share it with all the guest user in External Tenant 2 or even user from ADX Cluster Tenant.

Is Scenario 2 intended? is there any way to block that?

Hi @MosesLim 

We answered this on a different thread, but nevertheless answering for the benefit of others.

ADX dashboards do not support cross tenant sharing today.

When adding users to a tenant you can share with them dashboards with their guest identities.

That also means you cannot block sharing with other tenant users a specific dashboard as long as you have sharing permissions.

Link the correct procedure for guest users please.
