Samba4 AD have its own winbind daemon called winbindd:
# ps aux|grep -i winbind
root 1820 0.0 4.9 432100 50616 ? Ss 21:24 0:00
/usr/sbin/winbindd -D --option=server role check:inhibit=yes --foreground
root 1917 0.0 4.0 437788 41792 ? S 21:25 0:00
/usr/sbin/winbindd -D --option=server role check:inhibit=yes --foreground
root 2057 0.0 3.5 432100 35936 ? S 21:33 0:00
/usr/sbin/winbindd -D --option=server role check:inhibit=yes --foreground
Sernet packages will install it automatically:
# dpkg -l| grep -i "winbind"
ii sernet-samba-winbind 99:4.2.11-9
amd64 Samba nameservice integration server
