[Samba] Changing from samba 2-2.8a to 3.1 with ldap?

[Michal Gubik]

Hi, I am trying to upgrade from old samba to new one, I replaced the 
samba.schema for open-ldap, changed the smb.conf file to:
passdb backend = ldapsam:ldap//localhost added ldap amin dn and suffix 
options but it still aint working with the old ldap records? Do I have 
to dump the old records and update them with some changes to the ldap 
with new schema or is samba3 ldap backward compatible? Can anyone 
describe the process of migrating from old samba to new one with ldap?
