OpenLDAP Quick Tips: Replication Strategies

OpenLDAPOpen SourceSuretec Hi All,

Here's the 22nd tip in the "OpenLDAP Quick Tips" series:

"You are not sure what type of OpenLDAP replication to use, but you know you need to".

This tip won't actually go into the technical setup (and isn't very quick ;-) ) of the different replication types, we'll leave that for another set of tips. You can always read up on them yourself in the Replication section of the OpenLDAP 2.4 Administrator's Guide. Or if you're coming to the UKUUG's annual Large Installation Systems Administration (LISA) you'll be able to hear Howard Chu and myself give our talks:

- OpenLDAP Replication Strategies - Gavin Henry (Suretec Systems & OpenLDAP project)
- OpenLDAP and MySQL: Bridging the Data Model Divide - Howard Chu (Symas Corp. & OpenLDAP project).

Andrew Findlay (Skills 1st), another respected authority on LDAP[?] will also be giving a talk on Writing Access Control Policies for LDAP.

Anyway, on to the strategies.

Suretec partners Symas release a MySQL Cluster back-end for OpenLDAP

OpenLDAPOpen SourceSuretec
MySQL and Symas have worked together for much of 2008 to produce a back-ndb, a back-end module for OpenLDAP that uses MySQL Cluster’s networked clustered database technology for OpenLDAP. Initially, we were concerned about how this would turn out but the advantages of the clustering technology made it worth a try. It turned out much better than expected!

MySQL (Sun) has contributed the source of this back-end to the OpenLDAP project and it is available in source from the project now. We expect it to be included in the next OpenLDAP 2.4 Release (imminent). MySQL will be offering binary distributions for selected platforms by the end of September.

The news is out: OpenLDAP and the new MySQL NDB Backend

OpenLDAPOpen Source Suretec can now report that Symas, using MySQL’s NDB API, have developed an OpenLDAP backend which talks directly to the MySQL cluster storage engine, completely bypassing the SQL layer, in association with MySQL of course.

Others think this is good news too.

It is already Open Source and will be committed to the main OpenLDAP codebase when ready. (when is the PostgreSQL one out! ;-) )
