22 February 2007 - 22:35LDAP vs RDBMS (2 of 2)

Trey Drake of Sun (and assumedly of OpenDS) has posted a couple of articles on why LDAP is better than RDBMS systems for directory data. Here is the latest one (and the prior one). Good stuff.

For those who care, OpenLDAP introduced persistent search in its implementation of pull or sync replication (syncrepl) in OpenLDAP 2.2 a couple of years ago. We've considered surfacing it for enterprise use when customers have been curious but none have really pressed for the capability.

Yeah, Pat and Trey, let's keep an eye out for that first real DSML deployment

five comments:

OpenSSO/Access Manager (optionally) uses persistent search to keep its internal cache in order, so anyone using OpenLDAP with those (and I know that some folks are) would be interested in persistent search. Is it a ‘hidden feature’? How is it enabled?

@Pat Patterson: The persistent search feature is described in RFC4533. The OpenLDAP implementation is enabled using the syncprov overlay, documented in the slapo-syncprov(5) manpage. There’s also some discussion of it in the Syncrepl chapter of the Admin Guide. So no, it’s not a hidden feature…

@hyc: Cool – the way you said “surfacing it for enterprise use” kind of implied that it is somehow submerged. Now I know, I can point folks to the feature when they ask if OpenLDAP works with OpenSSO.
