[Samba] Primary group is 0 and contains 0 supplementary groups

[Robson Vitor Mendonça]

Dear,

I am having a problem configuring Samba 4 domain member. The main server
works only as AD and the second one will be for file sharing.

Looking at the logs I see errors like:

"UNIX token of user 0
Primary group is 0 and contains 0 supplementary groups"

Logs: https://pastebin.com/BR1W0X3E

smb.conf: https://pastebin.com/B5Ve41KG

Does anyone know what can it be?

Thanks!

Atenciosamente,
