I have a GeneXus 18 upgrade 8 Knowledge Base with GAM, generating .NET Core.

It has 2 Deployment Units: one for installing the customer-facing web frontend and another for the back office, which is also web-based. The deployment will be to two docker containers with different URL addresses, but they will share the same ApplicationID, Repository, and Identity Provider, with Single Sign-On enabled.

I understand that in this scenario, I will need to use the GAM Remote Authentication Type.

Do I need to define an Authentication Type for each Deployment Unit / Container?

I am asking because the GAM Remote Authentication Type only allows one Local Site URL, which must match one of the callback URLs defined in the application.
