[Samba] unix_primary_group = yes don t work

[Christian Daré]

Hi,

On a samba 4.9.4 fileserver using ad backend with rfc2307  , when i 
create a file from a Win10 client, it s always created with the rights 
user:"domain users".
I ve understood that with "unix_primary_group = yes" , the file should 
be created with the rights user:gidNumber .

Here is my config :
[global]
        security = ADS
        workgroup = SAMBA494
        realm = SAMBA494.UNIV-BREST.FR
        log file = /var/log/samba/%m.log
        log level = 1

        idmap config * : backend = tdb
        idmap config * : range = 700000001-800000000
        idmap config SAMBA494 : backend = ad
        idmap config SAMBA494 : range = 100000-4000000
        idmap config SAMBA494 : schema_mode = rfc2307

       idmap config SAMBA494 : unix_nss_info = yes
       idmap config SAMBA494 : unix_primary_group = yes

       username map = /etc/samba/samba_usermapping

     vfs objects = acl_xattr
     map acl inherit = yes
     store dos attributes = yes

     load printers = no
     printing = bsd
     printcap name = /dev/null
     disable spoolss = yes

     winbind enum users = yes
     winbind enum groups = yes
     winbind use default domain = yes

     usershare path =

[homes]
     comment = repertoires personnels
     browseable = no
     read only = no
     force create mode = 0755
     force directory mode = 0755
