Hi @Saurabh Sharma , this thread may be of help to you. You may need to add the users as external users before they can sign in. Take a look through that thread and let me know if you have any questions!
I have a requirement to register an application on Azure AD.
Scenario:- We have two production domains(with two-way trust) and their separated Azure tenants. Now we have to register an OnPrem application on Azure
Condition:- Both tenant users have to be authenticated and can use the application.
Note:- Authorization will be managed by the application owner
Could you please assist? is it possible to authenticate other tenant users?
