auditlogs not listed in monitor database

Hi!

I have an odd effect: Using ldapsearch -Q -Y EXTERNAL -H ldapi:/// -b 'cn=Databases,cn=monitor' -s sub '(monitoredInfo=mdb)' description monitoredInfo monitorCounter

I only get two databases: # Database 1, Databases, Monitor dn: cn=Database 1,cn=Databases,cn=Monitor monitoredInfo: mdb ... olmDbDirectory: /var/lib/ldap/

# Database 3, Databases, Monitor dn: cn=Database 3,cn=Databases,cn=Monitor monitoredInfo: mdb ... olmDbDirectory: /var/lib/ldap/audit/

However I have two mode MDB databases used as auditlog/changelog. Why aren't hose displayed?

Kind regards, Ulrich Windl
