[Samba] PDC migration from suse 8.2 - samba 2.2.7 ldap - to latest versions on ubuntu 8.04

[GG]

Hello Vladimir, John and all the NG :-)
Thanks so much for answering. I really hoped someone would :-)

So I installed Debian latest stable netinst on the future production
server and here are my issues in the quotes :-( no net command on my
suse 8.2

Cheers :-)
Giorgio

done :-) Debian Stable netinst

My ignorance comes out :-)
Must I set it different from the production server as FW points
production.domain.com - I have clients using DNS=oldPDC and PDC
forwards queries to FW. FW has pdc.domain.com defined to point to lan
ip.

slapcat -f /etc/openldap/ldap.conf -l /ldap.ldif
OK

thanks :-)

# net getdomainsid
-bash: net: command not found :-( and not found in yast

I understand it has to do with extracting the sid from
/etc/samba/secrets.tdb but how do I install the command? suse 8.2 yast
has now net package and googling net is.. well wow!

I see it only contains shares so I bet smb.conf would just keep all
the old settings rigth? /DATA will be rsynced
