Hi,

I am using openldap 2.4.23-12.el6.i686 for provider and openldap version 2.2.28-4AV1.1 for slave.

My configuration is Provider with proxy consumer on one machin and slave on another machine.

I am getting error “CSN too old, ignoring” in logs(provide-proxycosumer config)

Do my both provider and slave machines needs times synched using NTP or lag of few seconds is allowed (1-2 seconds)?

Thanks
