Sorry to be so long in replying, just a couple of comments about your 
smb.conf. You are running Samba as a standalone server and I do not 
think you need any more than this in '[global]':

[global]
     workgroup = peers
     netbios name = SHS1
     security = user
     unix password sync = yes
     cups options = raw
     printcap name = cups
     printing = cups

You also probably do not need '[homes]' & '[users]', they do virtually 
the same thing.

Coming back to your original problem about SIDs, How are you creating 
the users and groups ? and where ?

Are you using anything else with Samba (sssd for instance, I cannot see 
why you would, but stranger things have happened)

The thing is, you usually do not care about SIDs on a 'standalone 
server', you connect as a user with password and that's it.
