Sorry, but no it doesn't.

Lets walk through your smb.conf:

You do not need to set 'netbios name', Samba will fill it in for you.

You do not need the 'winbind enum' lines, they can just slow things
down, winbind has to enumerate all users and groups.

Now we come to the 'biggy', did you actually read the line above 'You
must set a DOMAIN backend configuration' ?
Obviously not, because you do not appear to have done so, I would expect
as a minimum:
idmap config OURDOMAIN : backend = rid
idmap config OURDOMAIN : range = 10000-999999
There are other idmap backends and you could use a different range, but
the ranges must not overlap.

Doesn't matter where Samba comes from, you set it up the same, just
