Thank You, Rowland.

I have already read that. According to chapter File System Support, does
that imply, that Samba could also well never grant Modify permission for
linux ACLs? Do I need extended ACLs on filesystem in order to do that? I
thought, that write permission on filesystem should be sufficient for
Samba to grant Modify for Windows...

As of smb.conf, here is snippet


   path = /mnt/data_disk/www/pripomienkovanie/
    dos filetime resolution = yes
    writable = yes
    read only = no

    preserve case = yes
    create mask = 775
    directory mask = 2775

    oplocks = false
    level2oplocks = false
