back-ldap core dump - openldap-technical

22 Nov 2010


      Hi
I have to migrate from a openldap 2.3.x to openldap 2.4. During this migration phase i want my openldap 2.3.x master replicate with slurpd to my new openldap 2.4.x master mirror mode architecture with some rewriting rules for split my big directory.
I configure a proxy ldap using back-ldap with slapo-rwm overlay, but  operational attributes  related  to  entry  creation and modification are proxied, even when i put < lastmod off > in the conf, contrary  of the man of slapd-ldap ...
So i put rw-map directives in the conf for strip operationnal attributes but this kind of operation generate a core dump ...
