Dear OpenLDAP developers, For bdb_modify and bdb_modrdn, there are two occassions to invoke bdb_psearch, one with LDAP_PSEARCH_BY_PREMODIFY, the other with LDAP_PSEARCH_BY_MODIFY. For other operations such as add, delete, there is only one occasion. Could you give a hint why it is like this? Thanks! Xingyuan
