[Freeipa-users] Server replication stopped working

Hi Ludwig,

Version:
389-ds-base-1.3.4.0-33.el7_2.x86_64

The timestamp probably matches the last time I've done a ipa-replica-manage
re-initialize.
I have to do it every day (many times a day actually!), as replication is
broken, This CSN changes all the time.

My main goal is to rebuilt everything from a clean base.
I've got no master without errors.

What is the easiest way to rebuilt everything?
ipa-[cs]replica-manage re-initialize isn't very effective.

Thanks by advance,
Regards
