how to delete backend DB

Hi

I am trying to delete a backend DB

Currently have dn: olcDatabase={-1}frontend,cn=config dn: olcDatabase={0}config,cn=config dn: olcDatabase={1}monitor,cn=config dn: olcDatabase={2}bdb,cn=config

I would like to delete olcDatabase={2}bdb,cn=config

I tried

ldapdelete -v "olcDatabase={2}bdb,cn=config"

note- I have ~/.ldaprc setup with URI & SAS_MECH

slapd will not let me do it ? I know I can shut down slapd and remove the file. But I am wondering if there is a "proper" way to do it

Thanks Alex
