There are conferences and there are Conferences. The Conferences are the ones that you remember, because they happened in unusual places, because they’ve had a different atmosphere, you’ve met lots of friendly and bright persons. They are the ones you leave with the satisfaction of having learned something, having received value, and you’re looking forward to come back next year.
The IRM Summit is one of these Conferences. The next European IRM Summit is taking place in November, 3 – 5, near Dublin, Ireland, at the Powerscourt Estate pictured here. It’s a 2 days event where you can learn and discuss about the Identity Relationship Management space, standards, platforms, solutions…There will be many presentations, demos, trainings, plenty of time for discussions and meetings, a free half day Kantara Initiative workshop around “Trusted IDentity Exchange (TIDX)”, and some fun. I can already hear the fiddle, the pipes, the harp and smell the Guinness ! And I hope the weather will let us enjoy the wonderful garden.
Check out the agenda and the list of speakers, and don’t wait until last minute to register. While there are hundreds of rooms available, they are still counted and limited. Last year’s summit was sold out !
I’m looking forward to see you in beautiful Ireland !
Four years ago, exactly I was free from all obligations with my previous employer and started to work for ForgeRock.
My first goal was to setup the French subsidiary and start thinking of building a team to take on development of what we named a coming later OpenDJ.
4 years later, I look at where we are with ForgeRock and I feel amazed and really proud of what we’ve built. ForgeRock is now well established global business with several hundreds of customers across the globe, and plenty of opportunities for growth. The company has grown to more than 200 employees worldwide and still expanding. The ForgeRock Grenoble Engineering Center has moved to new offices end of May and counts 13, soon 14 employees and we’re still hiring.
Thanks to the ForgeRock founders for the opportunity and let’s keep rocking !!!
My colleague Warren, who I had the pleasure to work with at Sun and again with ForgeRock, has been playing with Ansible and has produced 2 roles to install OpenDJ and to configure replication. Check Warren’s blog post for the details, or go directly to the Ansible Galaxy.
In the LDAP information model, a syntax constrains the structure and format of attribute values. OpenDJ defines and implements a large number of syntaxes (you can discover them by reading the ldapSyntaxes attribute from the cn=Schema entry).
But infrequently, we receive enquiries on an obscure and non standard syntax, often in the form of “I’m having an error importing schema from this or that legacy directory server”, with an error message that ends with “No such syntax is configured for use in the Directory Server”.
As syntaxes are constraining the structure and format of attribute values, they are implemented as code, specifically Java code in OpenDJ. It’s possible to implement new syntaxes by implementing the org.opends.server.api.AttributeSyntax abstract class, and installing the classes or the JAR in OpenDJ classpath. But often, it’s easier and more convenient to define a syntax by configuration, and OpenDJ offers 3 possibilities to define new syntaxes. In term of backward compatibility, I will only focus on the 2 main ones, by substitution and by pattern (the 3rd one allows to define enumeration of values).
With OpenDJ, you can define a new syntax by configuration and delegating the contraints to an already implemented syntax. A simple example is the URI syntax (which was defined is some very old schema with the OID 220.127.116.11.4.1.4401.1.1.1). A URI is really an ASCII string, and it might be sufficient to accept attributes with URI syntax to verify that all characters are pure ASCII. The standard syntax for ASCII strings is IA5String aka 18.104.22.168.4.1.1422.214.171.124.15.
ldapSyntaxes: ( 126.96.36.199.4.1.4401.1.1.1 DESC ‘URI’ X-SUBST ‘188.8.131.52.4.1.14184.108.40.206.15’ )
Insert the above line in the schema LDIF file before the attributeTypes, and you’re done.
The other option is to define the syntax as a pattern, using regular expressions. This could be better when willing to enforce additional constraints on an URI, for example, verifying that the URI is an LDAP one.
ldapSyntaxes: ( 999.999.999.1 DESC 'LDAP URI Syntax' X-PATTERN '^ldap://[-a-zA-Z0-9+&@#/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#/%=~_|]' )
So the next time you are trying to import some legacy schema to the OpenDJ directory server, and you have an error due to missing syntaxes, you know what to do to quickly resolve the problem.
The date has been set, the 2014 ForgeRock summit in United States will take place on the week of June 2nd, in Phoenix AZ.
Make sure you block the date in your calendar ! I hope to see you there.
And if you’re in Europe, don’t panic ! We are also planning an EMEA summit in the fall. The date and location will be announced later.
With OpenDJ 2.6.0, we’ve introduced a new way to access your directory data, using HTTP, REST and JSon. The REST to LDAP service, available either embedded in the OpenDJ server or as a standalone web application, is designed to facilitate the work of application developers. And to demonstrate the interest and the ease of use of that service, we’ve built a sample application for Android : the OpenDJ Contact Manager
The OpenDJ Contact Manager is an open source Android application that was built by Violette, one of the ForgeRock engineer working in the OpenDJ team. You can get the source code from the SVN repository : https://svn.forgerock.org/commons/mobile/contact-manager/trunk. Mark wrote some quite complete documentation for the project, with details on how to get and build the application. He published it at http://commons.forgerock.org/mobile/contact-manager/.
The whole application is just about 4000 lines of code, and most of it is dealing with the display itself. But you can find code that deals with asynchronous calls to the OpenDJ rest interface, with paging through results, and parsing the resulting JSON stream to populate the Contacts, including photos. Et voila :
The application is just a sample but it clearly is usable in its current form and will allow once a contact was retrieved from the OpenDJ directory, to add it to the Contacts standard application, call the person, locate its address on maps, send the person an email, navigate through the management chain…
In future versions, we are planning to add support for OAuth 2.0, removing the need to store credentials in the application settings.
As it’s open source, feel free to play with it, hack and contribute back your changes.
Last Monday and Tuesday (Nov 18-19), I was in Paris attending the 4th International LDAP Conference, an event I help to organize with LDAPGTF, a network of French actors in the LDAP and Identity space. ForgeRock was also one of the 3 gold sponsors of the conference along with Symas and Linagora.
The conference happens every other year and is usually organized by volunteers from the community. This year, the French guys were the most motivated, especially Clément Oudot from Linagora, leader of the LDAP Tool Box and lemonLDAP projects, and Emmanuel Lecharny one of the most active developers on Apache Directory Server.
I was honored to be the keynote and first speaker of the conference and presented “The Shift to Identity Relationship Management“, which was well received and raised a lot of interest from the audience.
The first day was focusing more on the users of LDAP and directory services technologies, and several presentations were made about REST interfaces to directory services, including the standard in progress: SCIM.
Kirian Ayyagari, from the Apache Directory project, presented his work on SCIM and the eSCIMo project. Present for the first time at LDAPCon, Microsoft’s Philippe Beraud spoke about Windows Azure Active Directory and its Graph API. And I talked about and demoed the REST to LDAP service that we’ve built in OpenDJ. For the demo, I used PostMan, a test client for HTTP and APIs, but also our newly open sourced sample application for Android : OpenDJ contact manager. In the afternoon, Peter Gietz talked about the work he did around SPML and SCIM leveraging OpenLDAP access log.
After many talks about REST, we had a series of talk around RBAC. Shawn McKinney presented the Fortress open source IAM project and more specifically the new work being done around RBAC. Then Peter, Shawn and Markus Widmer talked about the effort to build a common LDAP schema for RBAC. And Matthew Hardin talked about the OpenLDAP RBAC overlay bringing policy decisions within the directory when deploying Fortress.
Then followed presentations about local directory proxy services for security based on OpenLDAP, about Red Hat FreeIPA (another first appearance at LDAPCon) and about OpenLDAP configuration management with Apache Directory Studio. Also Stefan Fabel came all the way from Hawaii ( Aloha ! ) to present a directory based application for managing and reporting publications by a university: an interesting story about building directory schema and data model.
The day ended with a presentation from Clement Oudot about OpenLDAP and the password policy overlay. As usual, talking about the LDAP password policy internet-draft raises the question of when it will be finally published as an RFC. While there is a consensus that it’s important to have a standard reference document for it, I’m failing to see how we can dedicate resources to achieve that goal. Let’s see if someone will stand up and take the leadership on that project.
After such a long day of talks and discussion, most of the attendees converged to a nearby pub where we enjoyed beers and food while winding down the day through endless discussions.
The second day of LDAPCon 2013 was more focused on developers and the development of directory services. It was a mix of status and presentations of open source directory projects like OpenDJ, OpenLDAP or LSC, some discussions about backend services, performance design considerations and benchmarks, a talk about Spring LDAP… As usual, we had a little bit of a musical introduction to Howard Chu‘s presentation.
I enjoyed the Benchmark presentation by Jillian Kozyra, which was lively, rational and outlining the major difference between open source based products and closed source ones (although all closed source products were anonymized due to license restrictions). It’s worth noting that Jillian is pretty new in the directory space and she seems to have tried to be as fair as possible with her tests, but she did say that the best documented product and the easiest one to install and deploy is OpenDJ. Yeah !!! :-)
Another interesting talk was Christian Hollstein‘s about his “Distributed Virtual Transaction Directory Server“, a telco grade project he’s working on to serve the needs of the 4G network services (such as HSS, HLR…). It’s clear to me that telco operators and network equipment providers are now all converging to LDAP technologies for the network and this drives a lot of requirements on the products (something I knew since we started the OpenDS project at Sun, kept in mind while developing OpenDJ, even though right now our focus has mainly been on the large enterprises and consumer facing directory services).
All the slides of the conference have been made available online through the LDAPCon.org website and the Lanyrd event page. Audio has also been recorded and will be made available once processed. And as usual, all the photos that I took during the conference are publicly available in my Flickr LDAPCon 2013 Set. Feel free to copy for personal use.
It’s been a great edition of the LDAPCon and I’m looking forward to the next one, in 2 years !
Meanwhile I’d like to thanks the sponsors, all 75 attendees, the 19th speakers and the 2 organizers I had not mentioned yet : M.C. Jonathan Clarke and Benoit Mortier.
