OK, 4.13.2 with 'winbind use default domain = yes' works for myself and 
there isn't anything really wrong with your smb.conf, but there was this:

So, we have user dmu60evo in our domain, but on client machine, we are
not able to use username in format DOMAIN\dmu60evo. So we have to use
winbind use default domain = yes.

Why can you not use 'DOMAIN\dmu60evo' ?
Is dmu60evo a local Unix user as well as being in AD ?
