samba classicatualização de samba3 para samba4

  • 772

Estou muito confuso com a atualização do samba do samba 3.5 (debian squezze) para o samba 4.1 (ubuntu 14.04 lts) O que acabei agora? tudo da wiki oficial do samba:

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

Meu cenário é fazer backup do samba 3 existente na máquina antiga, transferir arquivos para a nova máquina e fazer a atualização clássica deste arquivo. Não consigo fazer a atualização clássica na máquina antiga porque está no site de produção e não pode estar indisponível.

Agora, na nova máquina, estou trabalhando com o ldap aberto com o banco de dados importado da máquina antiga e também tenho os arquivos smb.conf e /var/lib/samba/* da máquina antiga. Verifiquei o ldap em busca de nomes duplicados de usuários e grupos.

Para fazer classicupgrade eu executo o comando:

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

e a saída desse comando é:

Depois disso, a ferramenta samba pode listar usuários e grupos, mas não pode adicionar computadores e comandar

samba-tool ntacl sysvolreset

sair com erro:

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

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

Alguém pode me ajudar a entender o que estou fazendo de errado ou o que fechei para fazer mais?

Quando estou tentando fazer login como alguém para compartilhar a rede nos logs do samba4, tenho isto:

Acho que é algo com mapeamentos de grupos, mas não sei como consertar isso. Existe a possibilidade de editar alguns arquivos samba3 ou ldap, mesmo manualmente para corrigir esse problema?

    Ok, entendi, não devo copiar todos os arquivos de /var/lib/samba do servidor antigo, mas apenas estes arquivos:

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

    e use apenas este arquivo para o procedimento clássico de atualização.
