Hello Dimasf,

this is surely a configuration error. Since we have a connection error message and you say they can ping each other, I would check your firewall first.

Thank you Javier. I haven't indeed done anything with the master's firewall. I assume the firewall is set to Zentyal default. Any suggestion on which port/protocol I need to setup on the master's?

Thanks,

Hi Javier,

I set the master's firewall so that it allows an ldap connection from slave. By doing that, I was able to enable the Users & Groups module. Another problem then occured when I tried to save the changes.

I attached a new log for diagnosis purposes.

Thanks,

Dimas
