I'm very confused with doing samba upgrade from samba 3.5 (debian squezze) to samba 4.1 (ubuntu 14.04 lts) What i'm done now? all from official samba wiki:

[https://wiki.samba.org/index.php/Migrating_a_Samba_NT4_domain_to_a_Samba_AD_domain_%28classic_upgrade%29]

My scenario is to do backup of existing samba 3 on old machine, transfer files to new machine and do classicupgrade from this file. I can't do classicupgrade on old machine because is on production site and can't be unavailable.

Now on new machine i have working open ldap with imported database from old one, and also have files smb.conf and /var/lib/samba/* from old machine. I have checked ldap for duplicate names of users and groups.

To do classicupgrade i run command:

samba-tool domain classicupgrade --dbdir=/dir/with/files/from/old/machine/var/lib/samba/ --use-xattrs=yes \ 
--realm=office.mycompany.com --dns-backend=SAMBA_INTERNAL /patch/to/samba3/smb.conf

and the output of this command is:

After that samba-tool can list users and group but can't add computers, and command

samba-tool ntacl sysvolreset

exit with error:

ERROR(<class 'passdb.error'>): uncaught exception - Unable to get id for sid

    (BA_gid,BA_type) = s4_passdb.sid_to_id(BA_sid)

Can someone help me with understanding what i'm doing wrong or what i shut to do more ?

When i'm trying to log as someone to network share in samba4 logs i have this:

I think is something with groups mappings but don't know how to fix that. Is there possibility to edit some samba3 or ldap files , even manually to correct this problem ?

Regards

  • anybody ? i think is something with gorup mappings but not understand how to fix that – Łukasz Apr 18 '16 at 8:36

OK got it, i should not copy all files from /var/lib/samba from old server but only this files:

# secrets.tdb
# schannel_store.tdb
# passdb.tdb
# group_mapping.tdb
# account_policy.tdb
# smb.conf

and use only this file for classic upgrade procedure.
