I am trying to delete a complete tree, but i got the error messages:

ldap_delete: Other (e.g., implementation specific) error (80) ldap_prune: Other (e.g., implementation specific) error (80) ldap_delete: Operation not allowed on non-leaf (66) additional info: subordinate objects must be deleted first

But when i remove from /etc/openldap/slapd.conf the line:

index cn,uid eq

I can delete perfectly.

Does anybody know why?
