Did you follow the instructions on this wiki page:

getent should show your users where ever they are, in CN=Users or an OU.
However 'getent group' doesn't show groups, you need to run 'getent

What version of samba4 are you running, versions before 4.2.0 did not
run with a separate winbind daemon, from 4.2.0 onwards the same winbindd
deamon that is used with a 'classic' setup is used, but in all cases,
you should only start the 'samba' daemon, this will start any other

I have a feeling that you are using 4.2.0 , if so getent will not
display any users or groups unless you explicitly ask for one, i.e.
'getent passwd' will only show local users, but 'getent passwd fred'
would display the info for 'fred'. I should also point out now you are
using AD, you shouldn't retain any local users that are also in AD, pick
one or the other, but don't try and keep both.
