Sorry about that, I missed that out, try this one:
[global]
workgroup = WORKGROUP
vfs objects = catia fruit streams_xattr
fruit:delete_empty_adfiles = yes
fruit:metadata = stream
fruit:nfs_aces = no
fruit:veto_appledouble = no
fruit:wipe_intentionally_left_blank_rfork = yes
[NAS]
comment = RaspberryPi
path = /mnt/shared
read only = no
create mask = 0600
directory mask = 0700
[DatabaseShare]
comment = Database File Share
path = /mnt/shared/partage_de_fichiers
read only = no
create mask = 0660
directory mask = 0770
force group = sharedaccess
force create mode = 0660
The major problem people have with Samba is that they say it is hard to configure, all those parameters to set, totally missing that mostly they are setting defaults that do not need to be manually set.
You also may find it easier if you also install the acl and attr packages (they may be already installed) and use acl_xattr, so that:
vfs objects = catia fruit streams_xattr
Becomes:
vfs objects = catia fruit streams_xattr acl_xattr
map acl inherit = Yes
Then read up on setfacl and getfacl. These will allow you to set finer control on your directories and files.
You would then not require the 'create', 'directory' & 'force' lines.
