wbinfo -u and wbinfo -g return the expected list of users and groups:

Code:
wbinfo -u
NB\administrator
NB\jon
NB\billy
NB\will
But getent passwd and getent groups return only the local users and groups. What could I have done wrong? I have done the Google, many times very hard.

Code:
nsswitch.conf
passwd:         winbind compat ;lwidentity
group:          winbind compat
shadow:         winbind compat

hosts:          files dns
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files
Code:
smb.conf
