If the following line is in slapd.conf for the back_sql.la module:

id_query "SELECT id, keyval, oc_map_id, dn FROM ldap_entries WHERE pusername =
?"

Then slapd will not start and logs the following error:

Nov 30 12:00:59 testbrazilldap01 slapd[24111]: /etc/openldap/slapd.conf: line
36: unknown directive <id_query> inside backend database definition.

This worked correctly in version 2.4.23.

After looking through the code, the 'id_query' configuration appears to be
missing from servers/slapd/back-sql/config.c, while it was present in that file
for version 2.4.23.

I've sent a patch for config.c named paul-terry-151203.patch
