samba - Feb 2004 - Changing from samba 2-2.8a to 3.1 with ldap?

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?

why not start here...
<http://us1.samba.org/samba/docs/man/upgrading-to-3.0.html>

of course, you could look at the two schema's and recognize that the
objectclass is different (sambaAccount vs. sambaSamAccount) - which
pretty much means that you have work to do.

yes, you need to update ldap base.
dump it with the help of ldapsearch into some file, e.g. old.ldif:
  ldapsearch -LL -x -h <server> -D
"cn=Manager,dc=example,dc=com" -b "dc=example,dc=com" -w
"secret" > old.ldif

convert if with convert it with
   convertSambaAccount --input=old.ldif --output new.ldif --changetype=modify
--sid=<your-sid>

you may get <your-sid> invoking at PDC:
  net getlocalsid

convertSambaAccount is in <samba-source>/examples/LDAP, chmod it to make
executable.

now apply changes to LDAP: ldapmodify -D
"cn=Manager,dc=example,dc=com" -w "secret" -f new.ldif
