Some people cannot upgrade, so they have to use what they have, but
without knowing what OS the OP is using, we don't know if they can
upgrade easily.

Why ?

That is correct and 'man smb.conf' tells you not to do it this way, but
who reads manpages ;-)

It doesn't matter if there or not.

Well, Microsoft says you can use a netbios domain name that is
different from the left part of the DNS name, so I suppose Samba
should as well.

I notice it was missing as well, but the OP could be using something
else instead of winbind. 'idmap config' existed on 3.6.0, so it should
work.

Why recommend something, that the OP might not be able to do, without
all the facts.
