For sure we have 'rid' there ;-)

This would mean fiddling with the DM setup and new risks (afai
understand we would have to at least chown everything etc etc)

I prefer the smaller job: as the rsnapshots only have to be available to
2 or 3 users, I try to rsync "by name" and not with "--numeric-ids" as
it was done before. Maybe add "--chown" as well, we don't need too much
detail in the rsnapshots anyway. I test that now (waiting for such a
snapshot run currently).

Yes, sure, it could be improved, but I am getting tired and exhausted of
fiddling with AD-details at 2 sites lately. Remember these 2 words:
"holiday" and "vacation". When? When?
