Sorry, i say samba 3, meaning samba not AD but NT4-Style domain as i use samba 4.2 on this marchine.
It's a shame i can't use openldap user information on domain member, as mapping are already done there.
Using passdb backend = ldapsam:ldap://172.30.1.250/ works but i need to hack SID in sambaDomainName to match domain SID (meaning my member
SID for local machine matches SID for domain using net getdomainsid on client)

4.2 is EOL, but I think you know that ;-)

OK, your PDC needs to know who your users and groups are, but, like an
AD DC, you shouldn't use the PDC as a fileserver.

It doesn't actually, I created a test NT4-style domain last week, to
remind me how they worked, you create the users and groups on the PDC,
joining a computer creates a computer object in ldap on the PDC.
However, your users and groups get ID's from winbind based in the range
you set in the clients smb.conf

By 'samba 3' do you mean Samba version 3.x.x and if so, what version, or
do you mean an NT4-style domain ?
