Hello, I am upgrading my PDC server and samba. For samba it's a minor update (samba-3.0.9 to samba-3.0.10). same server name, same ip, same DOMAIN et same NETBIOS NAME. All users are in ldap (not the same server). I do not want to join all stations again so it is ok to : backup /etc/samba backup domain sid using net rpc getinfo aftter the upgrade : install the new version. add the ldap password in the secrets.tdb use net setlocalsid SID use the backup (smb.conf) start samba Is it a good technic ? Thanks !
