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 eu faço agora? todos do wiki oficial do samba:
[ link
Meu cenário é fazer backup do samba 3 existente na máquina antiga, transferir arquivos para a nova máquina e fazer o upgrade clássico desse arquivo. Eu não posso fazer o classicupgrade na máquina antiga porque está no site de produção e não pode estar indisponível.
Agora na nova máquina eu tenho o trabalho de abrir o ldap com o banco de dados importado do antigo, e também tenho os arquivos smb.conf e / var / lib / samba / * da máquina antiga. Eu verifiquei o ldap para nomes duplicados de usuários e grupos.
Para fazer o comando classicupgrade i run:
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 deste comando é:
eading smb.conf

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

sair com erro:

Alguém pode me ajudar a entender o que estou fazendo de errado ou o que eu calei para fazer mais?
Quando eu estou tentando logar como alguém para compartilhamento de rede em logs de samba4 eu tenho isso:

Eu acho que é algo com mapeamentos de grupos, mas não sei como corrigir isso. Existe a possibilidade de editar alguns arquivos samba3 ou ldap, mesmo manualmente, para corrigir este problema?
Atenciosamente
OK, eu não deveria copiar todos os arquivos do / 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.
