samba - Oct 2019 - Primary group is 0 and contains 0 supplementary groups

Rowland, thanks for listening. I am learning to use the list, this is the
first time I use this feature, sorry for the inconvenience, I believe it is
the last message that will be created as new. I changed my receive settings
to be able to reply to messages individually.
>From what you answered earlier, I have a main server with AD, running Samba
4, everything is configured and working. The error is happening on a
secondary server, which will be for files only. This secondary server
authenticates to the primary server, so the password server.

Groups have been created on the primary server so that users of these
groups can access their shares.

I believe I have some idmap error, or something, but as I have no
experience in Samba, I can't find my mistake.

Thanks!

Atenciosamente,
Robson Vitor Mendon?a

It sounds like your 'main server' is configured as a Samba AD Domain 
Controller (seeing the smb.conf from that computer would confirm this) 
and if so, should be referred to as a DC (it helps, a 'server' could be 
many things)

This sounds like a Unix domain member and the smb.conf you posted a link 
to, confirms this.

Nope, it isn't really referred to as a password server, if it is a DC, 
it is much more than that ;-)

AH, are you used to Samba3 ?

AD doesn't really work like that, well, not without doing other things.

Can you please post the the smb.conf from the other Samba computer.

Why do you need SMBv1 (ntlm auth = yes) ?

Once I have all this info, I will help you to write your smb.conf files 
correctly and help you to get things working.
