Issue ID: 10259 Summary: Wrong RID sends when using syncrepl provider Product: OpenLDAP Version: 2.6.8 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs@openldap.org Reporter: florent.david@gmail.com Target Milestone: ---

When using a custom syncrepl consumer bind to an OpenLDAP v2.6.8 provider and it quickly appears than this provider sends to our consumer a cookie with a Replica ID different from the original one.

In the logs below, we clearly see a refreshAndPersist synchronization initialized whith a RID with value 606. After a while, on the same connection, OpenLDAP syncrepl provider sends a new cookie with RID=612

Is it a normal behaviour ? Should consumer checks the Replica ID sends by OpenLDAP before storing it ?
