[Samba] samba 4 as a pdc and /etc/passwd

but my original question was do I need to duplicate all the accounts in
/etc/passwd between the two machines since I did not have ldap installed
originally? Will samba 4 and it's built-in ldap stuff capture what I need
to get through pdc to bdc replication?
