[Samba] getent passwd user no output, addc + dm

[Lin Pro]

There are two ubuntu 16.04 samba 4.5 servers. Ubuntu ADDC and a Member
(ubuntu-dm1)
>From Member "wbinfo -u" shows shows users of ADDC
>From Member "net ads join -U administrator" was successfull with no errors.
The dns A record was added in ADDC.

But getent passwd <user> shows no results.

DMember's /etc/nsswitch.conf
passwd:         compat winbind
group:          compat winbind
shadow:         compat
gshadow:        files

hosts:          files dns
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup:       nis


root at ubuntu-dm1:~# ldconfig -p |grep winbind
libnss_winbind.so.2 (libc6,x86-64) =>
/lib/x86_64-linux-gnu/libnss_winbind.so.2
