Access CIFS share over WebClient from Docker-Container as a host

Hi everybody,

we have the problem, that it is not possible to save files or open files in the webclient (in an report) from an CIFS share. Everything runs in a container. The service account that runs the service tier in the container.. Must he have the permissions to open that network share? Or the user that is currently logged in over the web client?

The container is running with a credential spec, so that it has connection to the domain.
But when I try to change the service account that is running the service tear, it doesn't run anymore. The domain account that I'm using has SQL permissions to have full access to the database.. And there are no usefull informations in the containers event log.

Thank you for your help!

best regards,
Robin
