[Samba] backend migration and Samba upgrade.

Prev: [Samba] 2 domains, 2 password servers and one Samba installation
Next: [Samba] Samba on top of Windows?
From: Bastien Semene on 5 May 2010 10:10 Short background : Due to Windows Seven deplaoyment we have to upgrade Samba 3.0 to Samba 3.4 (actually less version but I see no reason not to go directly to 3.4). And due to SQL backend support aborted we have to switch from SQL backend to LDAP backend. What I have in mind to do this migration is the following : -install samba 34/OpenLDAP (I also change the machine in the meantime) -configure Samba 34 to use the ldap backend, the smb.conf will be rewriten from scratch. - sync the sid with net getlocalsid and netsetlocalsid. -pdbedit -e to export users and pdbedit -eg to export groups (on the old server). -pdbedit -i and pdbedit -ig on the new server. -tests. I'm far to be an expert in Samba, so advices on this procedure are very welcome. While checking that everything should be ok, I did a pdbedit -L and many lines (less than 1000) like this one appeared : lookup_global_sam_rid: looking up RID 513. Executing query SELECT nt_logon_time,nt_logoff_time,nt_kickoff_time,nt_pass_last_set_time,nt_pass_can_change_time,nt_pass_must_change_time,username,nt_domain,nt_username,gecos,nt_homedir,nt_dir_drive,nt_logon Can't find a unix id for an unmapped group No user SID retrieved from database! There are 3 RIDs concerned : 513, 11001, 515. Can I correct this error before migrating ? Is it mandatory/interesting to correct this error ? This is the output of the testparm command : Load smb config files from /usr/local/etc/smb.conf Processing section "[netlogon]" Unknown parameter encountered: "readable" Ignoring unknown parameter "readable" Loaded services file OK.
