Perhaps I need to add a note about sssd.

Okay, can only speak for debian, but you need the glue that connects
Samba to nsswitch (a link to how to set this up was on the domain
member page, but it wasn't obvious, hopefully it is now), see here:

Do you have sssd installed, if so, make a decision, do you want too use
winbind or sssd ?

If sssd, stop using winbind and ignore the link above.
If winbind (which I suggest), stop using sssd

There is a problem with using Centos as the base OS, you must compile
Samba, the default OS Samba packages cannot be used to create a DC
