Another interesting things. Package libldap doesn't require libldap-data and as such /etc/openldap/ldap.conf file isn't there. Recommends: libldap-data >= 2.4.44 In case of upgrade 42.1 to 42.3 for example (with --no-recommends for obvious reasons on server), the old libldap rpm is removed, ldap.conf is saved as ldap.conf.rpmsave and no new is installed. I've seen here sysadmins thinking the file is no more needed. So there's two thing, if the file is not useful for having a running system, then recommends is the right tags. If file is mandatory (which seem clearly the case) then Requires is the right tag. After installing libldap-data package, restored old ldap.conf file a command using -ZZ is again working. An update would be really appreciate, and also a line in the Release note.
