I thought syncrepl is using entryCSN, not modification timestamp…

Maybe explain more detailed.

Kind regards,

Subject: [EXT] Translucent and Syncreplication

Hi,

We are currently setting up a new openLDAP service and face Problems when combining slapo-translucent and syncreplication.

To increase reliability and performance the new new openldap Server is behind a Loadbalancer which redirects requests to three instances.

These three instances sync config and data via syncrepl.

This works fine.

We also have a legacy LDAP Server that some of the data has to be stored and updated in during migration of other services.

For this we use the slapo-translucent functionality and that also works fine.

We now face problems when combing these two concepts. When stacking the syncrepl and translucent overlays the server is not starting because slapo-translucent/slapd-ldap is setting olcLastMod to false.

This has come up many times in this list but I was unable to find a solution. Is there another setup to combine translucent with high availability?

Mit freundlichen Grüßen

Clemens (Bergmann)
