Apache Directory Server, Stored Procedures and Triggers for LDAP.

LudoLeave a comment

Ersin Er from the Apache Software Foundation exposed his experimentations with Stored Procedures in LDAP and how they are used with Triggers.

Stored Procedures are code (java bytecode) stored in LDAP objects executed by a generic LDAP Extended request to pass parameters and get returned result and values.

Triggers are specifying an event, action,time and a scope in a single attribute definition, and leverage stored procedures for actions. Events are predefined, and triggers are run within an Administration domain (Subtree Specification). Pretty neat ! I think this is not a new idea, but it looks like a simplification in the use of the plugins and tasks that exist in Sun Directory Server and OpenDS. There might be value in a common representation of such LDAP directory server extensions, but I’m afraid this will not lead to better interoperability as Stored Procedures will be very specific to each implementation.

LDAPCon – Day 2

Ludo1 Comment

I’ve noticed that Jan-Piet Mens is also blogging live from LDAPCon. And yet we had a good evening with lively and hilarious discussions between the OpenLDAP, OpenDS, Isode, ApacheDS developers.

Steven Legg (eB2Bcom.com) exposed his work on XML enabled Directories also known as XLDAP. Most of the protocol and data model has been conducted through IETF. So far Steven has been the only one to produce an implementation. It’s not really surprising: one need to be both an expert in LDAP and XML processing to get an idea of what XLDAP is. But I recently got a question indirectly from a customer about XLDAP and whether we had any plan to implemented. Could it be that XLDAP is starting to raise interest ?

Andre Posner from Sun showed the use cases and added value of Sun Directory Proxy Server 6.x for security, availability, integration of different Directory Servers, migration of services.

LDAPCon day 1, afternoon

LudoLeave a comment

It was a long afternoon at the LDAPCon with presentations until nearly 8pm. Thanks to the organizers it was followed by a social event with food and free drinks. A good occasion to relax, taste the local beer, recall the old LDAP stories and redo the world until exhaustion of fuel :-).

Frank Tröger exposed his work on a Reference Schema for Identity Management, searching, sort and linking all of the LDAP schema that have been defined in that area (with a focus on higher education).

Daniel Pluta from Munich University of Technology talked about Access controls for Group and Role management.

Giovanni Baruzzi from Syntlogo presented his thought on Designing a Directory Tree. In a nutshell, keep it simple:

"As flat as possible, as deep as needed"

Hilla Reynolds, Director of Development at CA revealed in a very animated and humorous presentation her secrets for a "Seamless Directory Backbone service": Standards, distribution, failover… Applications access front-ends that deal with the real sources of information.

Other sessions I did not attend (split sessions) included a presentation of the Apache Directory Studio (formelly known as LDAP studio). Impressive tool and progress since I last downloaded it. And a presentation on Spring LDAP.
