Re: "best" way to check if OpenLDAP replication is working

I can attest to that.  :)

Reloading a server used to be required at least once a month or so before we updated from 2.3 to 2.4.23 openldap (5 servers, including the single master) due to being out of sync.

I think that a lot of our replication woes are the result of running some pretty ancient versions of OpenLDAP.  I'm in the process right now of upgrading our LDAP infrastructure to use all new 2.4.25 installations (rather than the 2.3.43 version that's bundled with CentOS) and I'm thinking that a lot of our replication issues might vanish once that upgrade is complete.
