We have an on-premise application that needs to accessed by internal users & external users (Guest account) in Azure tenant A. So is it possible to have only a trust between them as B2B collaboration.
What we want to archive is that Azure tenant B should
i)Access the application & they can onboard and additional users(contractors) as guest users in Azure tenant B.
ii) Azure tenant B users to mange the access (via groups that exist in Azure tenant A) for their guest users.
Note: We want to avoid federation
Or any other option please suggest
