The sync script runs as Administrator on the Win server as I wrote earlier.
After doing the 4.12 -> 4.15 upgrade earlier this week, the script failed
with a "Permission denied" and something about "ACL not
copied". I googled
that error message combined with Samba and found a link that mentioned
that mapping root to administrator via user.map was not working any more
(by design if I remember correctly). Unfortunately I did not save that
search and/or link. Anyway, I disabled the user.map option and then the
replication worked again (except the date issue in my original mail)
