So this just happened during an upgrade? Do I assume that it was in the manual that you needed to do this, and it was overlooked? or that the devs didn't bother to tell you, confirm that config during upgrade, etc?

I don't know the source of the change. It happened during a cert renewal.

This is with your LDAP SSL not with the Host SSL Certificate correct?

In theory they should be the same.

@scottalanmiller Thanks... That did the trick.

I am still trying to understand this issue, but it is probably due to having multiple Zimbra servers in a pool. Usually in one Zimbra Server setup that usually doesn't happen.

No, we don't use a pool here.

Had this error after installing a new commercial certificate. The error seems valid as my server hostname and certificate name do not match, but it is my understanding this name mismatch is allowed and should still work.
To resolve this I just ran these two commands as Zimbra user.
zmlocalconfig -e ldap_starttls_required=false
zmlocalconfig -e ldap_starttls_supported=0I am slightly concerned as to the security implications of disabling these settings. I am still on ldap not ldaps and this is on CentOS 7.
