Cannot save peristent value for postfix

Hi, i'm struggling with strange carbonio behavior. It's new installation and i need save this postfix var.
smtp_sasl_auth_enable with value no.
i used postconf -e and zmlocalconfig -e .
In localconfig.xml is correct value, even the runtime change works. But when i restart services, this value has wrong value.
It is some LDAP problem?

Please help.

Thank you
