[Samba] RV: Security tab missing, and another error

[Oscar .]

Hi all.

I have Samba 4.2.8 in a Debian Virtual Machine, i have domain, can join a Windows 10 machine to domain, and i have logged with “administrator” domain account in my Windows 10 machine, wih RSAT tools i can create users etc

The problem is with a created folder in server.

Mkdir /usuarios

Smb.conf:

# Global parameters
[global]
        workgroup = PDC
        realm = PDC.CASA
        netbios name = SAMBA
        server role = active directory domain controller
        dns forwarder = 8.8.8.8
        vfs objects = acl_xattr
        map acl inherit = yes
        store dos attributes = yes

[netlogon]
        path = /var/lib/samba/sysvol/pdc.casa/scripts
        read only = No

[sysvol]
        path = /var/lib/samba/sysvol
        read only = No

[usuarios]
        path = /usuarios
        read only = No

I have done too :

net rpc rights grant 'pcd.casa\Domain Admins' SeDiskOperatorPrivilege -Uadministrator
successful

i cannot set permissions in security tab because there is no security tab in Windows 10 accessing \\pdc.casa

also <getent group "Domain Admins"> dont return anything and if i write <chgrp "Domain Admins" /usuarios> :

chgrp: group invalid: «Domain Admins»

i have acl in fstab :

user_xattr,acl,barrier=1,errors=remount-ro 0       1

What can i solve this 2 problems please?

Thanks all!
