Removing entries from cn=config

Hi all,

I've been trying cn=config for some time now but I have a question: I can add/modify entries using ldapadd/ldapmodify, but so far I have not found a way to remove configurations without stopping slapd, going to slapd.d and manually removing the entry from there. What is the proper way to remove entries? If I try to remove the monitor database I get this error, for example:

# ldapdelete -x -Dcn=admin,cn=config olcDatabase={2}monitor,cn=config -W Enter LDAP Password: ldap_delete: Server is unwilling to perform (53)

I've tried to google it but had no success. Thank you!
