(ITS#6720) back-ldap core dump

Full_Name: olivier chirossel
Version: 2.4.23
OS: linux
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (



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

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 ?
