SOGo com Zentyal ADDC

Acabei de atualizar uma instância do Zentyal de 4.1 para 5.0.1. Após a atualização, o SOGo não permite mais o login dos usuários. Os usuários podem acessar outros serviços do Zentyal, como compartilhamentos e logon de domínio, mas o SOGo recusa as mesmas credenciais.

Eu tentei copiar /etc/sogo/sogo.confda instalação antiga para a nova. Eu também tentei limpar os novos sogoe zentyal-sogopacotes e instalá-los novamente, mas isso levou a uma situação pior (sem conexão Mysql e todo o /etc/sogo/sogo.confcomentário).

No arquivo /var/log/sogo/sogo.log recebo:

Jan 31 09:40:41 sogod [13184]: <0x0x561c14f67ce0[LDAPSource]> <NSException: 0x561c155e19b0> NAME:LDAPException REASON:operation bind failed: Invalid credentials (0x31) INFO:{"error_code" = 49; login = "cn=direzione di agape,cn=users,dc=ufficio,dc=lan"; }

Aqui está o que acredito ser a parte relevante do meu sogo.conf atual (o que funcionava na versão antiga):

Você pode me ajudar a identificar o problema?

EDIT: Olhando aqui , se entendi o bug report corretamente, parece que preciso editar o meu sogo.confpor causa de uma mudança introduzida no SOGo algum tempo entre a versão 3.0.2 e a versão 3.2.4. Esse pode ser o culpado, porque o Zentyal 4.1 empacota o SOGo 2.3.2, enquanto o Zentyal 5 empacota o SOGo 3.2.10. No entanto, mesmo supondo que seja esse o problema, não entendo como devo editar meu sogo.conf...

EDIT 2: Encontrei este comando que poderia lançar alguma luz, se eu pudesse entender sua saída ... Suponho que mostra o que o SOGo entende lendo o arquivo de configuração, mas não sei o significado da maioria definições:

EDIT 3: I've tried purging SOGo and installing it again, then activating it again in the Zentyal control panel. This time Zentyal configured SOGo MySQL connection correctly, so that at least SOGo starts up, but the login problem is still there.

EDIT 4: I've added one more line from the logfile above, maybe it helps
