[Samba] coexisting with samba2-ldap and samba3-ldap

[aux]

Hi, in my local network i have two samba server (2.2.8a) :


[samba-2.2.8a-ldap PDC and OpenLDAP server]-> contains scripts,policies
[samba-2.2.8a-ldap File server] -> contains data (160GB)

Recently i upgrade PDC to samba 3.0.12 and OpenLDAP server(2.2.23).
The PDC works correctly but when the scripts mount a share from samba FS
not works because still using old ldap attributes.

I'm trying to change some parameters, for example (smb.conf):

ldap filter = (&(uid=%u)(objectclass=sambaSamAccount))

and in /etc/ldap.conf:

nss_map_objectclass sambaAccount sambaSamAccount
nss_map_attribute pwdLastSet sambaPwdLastSet
nss_map_attribute logonTime sambaLogonTime
[...]

many attributes (old rid, old primaryGroupID, etc.) are not identical
and i don't know if i can map this and i don't know if samba take into
account the /etc/ldap.conf configuration.

exists some way to do this without having to update everything to
version 3?

thanks
