Yes, the ones that wear red hats ;-)

Yes, Samba is designed to use winbind and actually expects it.

The computer has a hostname, it also has a domain name, it also a fully
qualified domain name which is made up of the 'hostname' joined to the
domain name. If 'hostname' contains the fqdn, it is possible that the
fqdn may be hostname.example.com.example.com

The 'some distros' you refer to are probably the red-hat ones, why they
set /etc/hostname to the fqdn, I do not know, but whenever I have set
up Samba on Centos, I always have to remove the domain
from /etc/hostname
