[Samba] How to Samba share with mixed Active Directory 'Classic' authentication

I have a Samba4 AD Domain with one of the file servers as a domain member. This file server
host the main network shares for the domain. Currently, Windows users mapping this share are
authenticated using their AD domain credentials. That all works just fine.

What I want to do now is ALSO allow a user on a network host which IS NOT a domain member, and
the user is not domain users to also map/mount this share, possibly via the "Classic"
'security = user' mechanism. Can this be done? That is, can both mechanisms be accomodated somehow?

Below is the current smb.conf with 'security = ADS' and various idmaps.

netbios name = OHPRSSTORAGE

# workgroup = NT-Domain-Name or Workgroup-Name, eg: LINUX2
#   workgroup = WORKGROUP

# server string is the equivalent of the NT Description field
   server string = HPRS NAS server
