Package: kopano-server Version: 8.7.0-3 The default AppArmor configuration file /etc/apparmor.d/usr.sbin.kopano-server doesn't cover the default LDAP configuration files, which are left by default in /usr/share/kopano/ldap.*.cfg and just included from /etc/kopano/ldap.cfg (which is the Kopano recommendation).
Adding "/usr/share/kopano/ldap.*.cfg r," to /etc/apparmor.d/usr.sbin.kopano-server seems to help.
