yes, you are right, in effect I can't find PC names in users

$ wbinfo --domain-users | grep $(hostname)

or in groups

$ wbinfo --domain-groups | grep $(hostname)

but for PAM the PC is a user:

$ getent passwd $(wbinfo --own-domain)\\$(hostname)$

and it is a group too:

$ getent group $(wbinfo --own-domain)\\$(hostname)$

in my nsswitch.conf I have only set:

$ grep winbind /etc/nsswitch.conf
passwd:         files winbind systemd
group:          files winbind systemd

There is something else I have to do to instruct PAM how to get users?

from debian stretch with built-in samba 4.5.16 to debian bookworm with 
built-in samba 4.17.3.

$ grep mkhomedir /etc/security/pam_winbind.conf
mkhomedir = yes

I don't know, I was thinking was inside the smb protocol but... never 
take anything for granted ;)

Best regards
