I just updated a webapp server (3.4.21) from Ubuntu 16.04 to Ubuntu 18.04 and detected that the files plugin needs now the workgroup/domain name. This was just optional in the past.

So all users need to configure there folders again, and they need to know the workgroup name.

I tried to set our workgroup as a default entry, but there is no define option in the config-files.php. Is it just not documented or is there no possibility to set a default ?
