That said, I don't recall syncrepl ever working in 2.2.x and have used
slurpd for replicating with 2.2 but if the OP says he thinks he had it
running, well, I'm not gonna argue with him.

syncrepl 2.2.x works fine between CentOS 4 systems as installed via
yum.  I just used this today, made changes on the master that I needed
on to use on the slave, the replication was instant.

The issue is between 2.2.x and 2.3.x.  What I said I thought worked
was replication from CentOS 4.x to CentOS 5.x (ie. 2.2.x -> 2.3.x), as
when I brought the CentOS 5.x on-line and started slapd,  the LDAP
database was almost instantly available.  I never used any other
method to load the LDAP data on the CentOS 5.x system from the CentOS
4.x master.

It is only recently that I noticed the replication failing, I believe
after a recent yum update.

I have looked at using yum to regress the version of LDAP on the
CentOS 5.x system, but it seems I needed to have turned on a yum
option before the update to do this.  I also noticed all the
dependencies as far as trying to build myself.

My assumption is that eventually newer versions of LDAP will be
available that will work.

There is an openldap in the CentOS Testing repo for centos-4 that will work with centos-5.

It has a compat-openldap-<c4_version> for the things that are compiled against the c4 version ... and i am using it in production and syncing c5 and c4.

However, it is a couple updates behind.

The version is 	openldap-2.3.27-4.el4.centos

Thanks,
Johnny Hughes
