samba - Dec 2015 - Fruit module configured to use matter still write ._* files

I have configured samba as follow:

[global]
workgroup = GOYMAN
netbios name = MATRIX
security = user
encrypt passwords = yes
smb passwd file = /var/db/samba4/private/passdb.ntdb
vfs objects = catia fruit streams_xattr
fruit:resource = xattr
fruit:metadata = netatalk
fruit:locking = netatalk
fruit:encoding = private

[projects]
path = /data/projects
write list = kuon, ino
force create mode = 0770
create mask = 0770


I expect "fruit:resource = xattr" to avoid the creation of ._ files,
but I still get some.

If I add a tag with the OSX finder, the tag get stored as an extended attribute.

But I copied an illustrator file (.ai) and I got a ._ file generated alongside
it. The thing is I also got some metadata on the file itself.

kuon at matrix /d/projects ❯❯❯ ls -la
drwxrwxrwx  20 kuon  users       24 Dec 22 00:38 .

I'm using FreeBSD with ZFS, samba is 4.3.1


Thanks

cf man vfs_fruit:

"fruit:resource = xattr" only works on Solaris or a Solaris
descendant, because it not only requires support for xattrs of
arbitrary size, but also that the POSIX file IO API (open, read, write
asf) works with xattrs.
