a few Linux boxes share ldap (multi-master) backend that PAM/SSSD uses to authenticated users, and these LDAPs are also is used by Samba, users start @ uid 1000.
Boxes are in the same both DNS and Samba domains.
Do I treat these users as system or virtual users from postfix/dovecot perspective?
If it can be a matter of choice then which is better/best? many thanks.
