Process :
- In Admin of Files Service, do not give rights to groupe "Client" (Not in "Files administrators" or "File readers"
- Connect with a user of the group "Client"
- The user see the "Files" Tab
It is also possible to give access rights to a package to a group even if the group does not have access to the service, which is not consistent.
As an administrator, it feels like giving access rights for a group to a package when the group does not have access to the service.
