Hi to all!
I've set up Zimbra LDAP (2.4) as master, and I want to use RHEL v5 LDAP
(2.3) as a slave. This is relevant part of my slapd.conf on LDAP 2.3:
This won't work. The format of the contextCSN changed between 2.3 and
2.4. A 2.3 replica does not have the code in it to normalize the
differences. The only supported 2.3/2.4 replica that is support is
with a 2.3.43 master and a later version of 2.4. In the early
versions of 2.4 there was a problem with comparison of the two
contextCSN formats. Not sure exactly which version fixed the problem,
but by 2.4.19 it was working.

Replication works OK, when I first start LDAP, it populates
automatically. But after that initial data, it just doesn't pull
anything anymore. I have to restart it, or it won't pull data from
Master :( Problem is, when I add user to Zimbra LDAP (master), it does
not propagate immediately data to slave LDAP. I don't even know what the
interval is, I've never seen it happen in a few minutes after the Master
LDAP is updated...
Am I missing something? Shouldn't "refreshAndPersist" do it without any
delay (or with minimal delay)? Should I run someting on zimbra LDAP
side, or is the sync from LDAP 2.4 to LDAP 2.3 impossible? Would it be
better to set something like:
but this just seems like a bruteforce to me :( I repeat, after I restart
slave LDAP, all the new enteries appear magically.
I'm really confused.
