[Samba] Unshow of domain name

[basti.mueller31 at web.de]

Hi,

I migrated my Samba 4 PDC to a AD. Everything works well. I've switched from OpenLDAP to Winbindd after the migration.

No I've this problem:
Linux (for example via "ll") shows the Name of Domain in front of user/group.
root at server:/media/intranet# ll
insgesamt 28K
drwxrwx---+  4 root                root                  4,0K Aug 10 09:05 ./
drwxr-xr-x  22 root                root                  4,0K Aug  9 14:03 ../
drwxrwx---+ 19 COMPANY\fileadmin COMPANY\mitarbeiter 4,0K Jul 27 12:03 01_Test/

and if I just use getfacl I've "134" in front (cause of the backslash?)
root at server:/media/intranet# getfacl 01_Test/
# file: 01_Test/
# owner: COMPANY\134fileadmin
# group: COMPANY\134mitarbeiter
user::rwx
group::---
group:BUILTIN\134administrators:rwx
group:COMPANY\134mitarbeiter:rwx
mask::rwx
other::---

Is there a way to unshow these Domainnames? My configurations:
smb.conf:
[global]
        netbios name = PDC
        realm = COMPANY.COM
        workgroup = COMPANY
        server role = active directory domain controller
        idmap_ldb:use rfc2307 = yes
        template shell = /bin/bash
        template homedir= /home/%U
        dns forwarder = 8.8.8.8
        min protocol = SMB2
        winbind enum users = yes
        winbind enum groups = yes

/etc/nsswitch.conf
passwd:         compat winbind
group:          compat winbind
shadow:         compat 
hosts:          files dns
networks:       files
protocols:      db files 
services:       db files 
ethers:         db files 
rpc:            db files 
netgroup:       nis 

thanks for help.
