What are you feelings on using the command line ?
You could always open a terminal on the Samba 4 DC, enter:

ldbedit -e nano -H /usr/local/samba/private/sam.ldb

press enter

press Ctrl+w
type 'dn: cn=domain users'
then add 'gidNumber: <whatever number you want to use>'
I suggest 10000
Press Ctrl+x
Press 'y'
Press 'enter'

That's it, Domain Users now has a gidNumber.

Ah, but setting up libnss_winbind is the same as on a domain member, go 
here and read the info:


remember to follow the links.

You may need another file, if getent doesn't work after setting up the 
links, just say and I will post the possibly missing file.
