After some testing there's actually more not working, for instance: the collectsummary.php script doesn;t return any values (all 0), ut if I try the ldapquery manually, it actually gives non-zero results:
ra% ldapsearch -x -D "cn=root,dc=boosten,dc=org" -W -b "cn=operations,cn=monitor" -LLL '(cn=modify)' monitorOpCompleted
Enter LDAP Password:
dn: cn=Modify,cn=Operations,cn=Monitor
monitorOpCompleted: 19
and from the cli log:
0 ) modify - Summary Value: 0
0 ) modify - Value NOT Stored to db as it is empty
I'm on OpenLDAP 2.4.23, on FreeBSD.
