Hello,

We currently have a multi server setup. Primary server has all services enabled, secondary server has all services except logger enabled and ldap is set as a replica.

If we need to bring down the Primary server to patch OS for example, we were under the impression that secondary would still work for their own local mail store. Login to the GUI works fine, however we cannot send out email.

Looking in the logs, it seems postfix is trying to query the master ldap.

Code:

ldap-vad.cf still points to the master ldap.
