[CentOS] LDAP syncrepl incompatibility between CentOS 4.x and 5.x

All,

After many hours of research I have found there is a incompatibility between OpenLDAP V2.3.x and V2.2.x, or atleast between V2.3.27 the current version on CentOS V5 and V2.2.13 the current version on CentOS V4.

The syncrepl feature of OpenLDAP, to keep multiple slapd servers sync'd, was working between CentOS 4 and 5 at one time, as that is how I populated the "slave" servers.

I've found references indicating protocol changes and incompatibilities between these versions and indeed looking at detailed debugging logs I can see the protocol falling apart between the two versions.

Has anyone else seen this issue? Is anyone aware of a fix in the pipeline or a work around?

Thanks in advance,

Brett
