samba - May 2015 - Import idmap database error on classicupgrade process

I copied all the database files of samba3 as is mentioned in the wiki - The
classicupgrade process
<https://wiki.samba.org/index.php/Samba_Classic_Upgrade_(NT4-style_domain_to_AD)#The_classicupgrade_process>

But if the winbindd_idmap.tdb file is in the folder, the errors occur. See
below:

IDMAP_VERSION_V2

If I remove/delete the file, the provisioning continues and tells me he did
not find the file: *Can not open database idmap, Ignoring: [Errno 2] No
such file or directory*

Can I still provisioning without the file? There is the possibility of
post-migration issues regarding lack of this file?

Hi, on the wiki page, it tells you to copy:

secrets.tdb
schannel_store.tdb
passdb.tdb
gencache_notrans.tdb
group_mapping.tdb
account_policy.tdb

It does not mention 'winbindd_idmap.tdb'.

So why are you including it ?

Rowland

You're right, man! Sorry! My mistake!

I put that file because I read in somewhere about the persistent and
temporary files regarding .tdb files. The winbindd_idamp.tbm was on that
list, and I think that's why I left it in the folder. :D

Another doubt. For the provisioning starts, I had to comment out the line
referring to the ldap backend in the smb.conf of samba3.

# passdb backend   = ldapsam:ldap://empresa.com

This can affect the provisioning?
