Jack and Pat on OpenSSO and OpenDS...

Pat Patterson reminded me of a conversation he had at OSCON 2009 with Jack Adams about OpenSSO. Luckily, the discussion was captured in video.
During the conversation, they talk about OpenDS as well. Thanks for the plug, Pat !

Another new feature in OpenDS Control Panel

Opends Logo TagOpenDS 2.0 has been out for a couple of months now but the development team kept on the pace of development.

Beside its ability to manage remote OpenDS servers, the Control Panel has been enhanced to support the Recurrent Tasks introduced in the OpenDS 2.0 server, and both Export LDIF and Backup can be scheduled to happen at a later time or on a regular basis.

Managing multiple OpenDS servers

Opends Logo Tag
Up until now, to manage an OpenDS server, one would need to log onto the machine and starts the Control Panel.

In the next release of OpenDS (OpenDS 2.2), the Control Panel can now connect to remote servers, allowing an administrator to remotely monitor and tune any running instance of OpenDS.

Let's see what has changed in the Control Panel for the remote access, and what are the limitations.

The first thing you will notice when starting the Control Panel is a new dialog which allows you to choose between the local server or a remote server.
OpenDS Control Panel, connection dialogOpenDS Control Panel new connection dialog

Once you've selected the server to administer, you will see the usual Control Panel window with its left action bar and information on the right.
OpenDS Control Panel remote server view

You can change server while the Control Panel is running. It's in the File menu, when you are on the Main window of the Control Panel.
OpenDS Control Panel, Changing Server to Administer
OpenDS Control Panel,  Changing Server to Administer

There is very little difference between managing a local server and managing a remote server.
One thing you will notice when administering a remote server is that you can't stop or restart it. Also, you cannot use the Control Panel to configure the Java properties of a remote server. That's it.

The Control Panel cannot be installed as a standalone tool, it's a part of the OpenDS server installation, and it can only manage one server at a time, local or remote. But the ability to manage remote servers will reduce the need to logon to each host and run the Control Panel on each instance either physically or using a remote display, simplifying the task of the directory administrators.

If you want to check this capability, you can download and install one of the recent OpenDS daily builds, or wait for next promoted build (2.1.0-build001).

Everything has an end...

And so do vacations, and blog silence.

I've been back in the office for over a week now but I was trying to catch up with emails, irc, blogs and news, too busy to find the time to blog again.
There's a lot to say on the LDAP and OpenDS front.

While I was happily riding the Mont Ventoux and around with friends and family, the project kept on moving on the path to OpenDS 2.2 and several new features have been committed by the team in the code repository:

  • The Control Panel can now be used to manage remote server instances.
  • OpenDS now publishes all changes in a public ChangeLog accessible (subject to access control) under the cn=changelog naming context.
  • Replication now supports a Fractional mode allowing to exclude or include only specific attributes of all replicated entries.
  • dsreplication utility has been improved to allow separating the replication service from the replicated OpenDS instance.
  • The import feature has been rewritten and optimized, reducing the time and memory required to import very large set of data.
  • The server now supports 2 new MatchingRules to better deal with Time and Dates (GeneralizedTime syntax).
  • The server now supports the ability to declare a new syntax but default it's implementation to an existing one.
  • The server now supports the ability to declare new Regular Expression based syntaxes and attributes.
  • The server now supports the ability to declare new Enumeration based syntaxes and attributes.

Most of the new features are already documented as part of the User Documentation of the OpenDS documentation wiki. You can test these features in recent daily builds, or you can wait for the next promoted build (2.1.0-build001) that should come pretty soon.
I will be starting a series of articles to describe with illustrations and details those new features, in the coming days and weeks.

Also in a separated branch, Matt and Bo have been working on an LDAP Client API, which is getting in a good shape to be released for beta testing soon (probably along with OpenDS 2.2).

LDAPCon 2009
The 2nd. International conference on LDAP, LDAPCon 2009 will be held on September 20th and 21st at Waterfront Marriot Hotel , Portland OR, USA. If you haven't registered yet, please register now ! The registration fee includes access to the LinuxCon 2009 (Sep 21 - 23), and if you still need to be convinced that it's worth attending, you can check the agenda. I hope to see you there.

Also noticed in the blogosphere and the websphere :

Finally I know the title of this post may have alarmed some of you. I don't know what's going to happen in the coming days, but I just hope I won't have to write another post with the same title on the subject of OpenDS or myself.

The Agenda for the 2nd International LDAP Conference (LDAPCon 2009).

The agenda for the 2nd International LDAP Conference has been published, and the conference really looks very attractive to me (sure I'll be presenting and thus I'm a little bit biased Angelic). I can't wait to be in Portland OR, meet with all the LDAP experts from the various open source projects or directory services vendors and have those lively discussions.
I hope to see you there.

Updated script for OpenDS.

Opends Logo TagBack in March, in the series of OpenDS tips, I had written an article and a script to help converting schema files for OpenLDAP to a format suitable for OpenDS.

I received multiple suggestions for the scripts as well as sample schema files that would not load in OpenDS after being converted. Most of the time, it was due to the lack of respect of the RFC syntaxes.
Recently, I found the time to update the script and produce better conversion. You can get the python script here. The March article has been refreshed with the new script as well.

OpenDS turns 3 today...

OpenDS open source project is 3 years oldAnother year has passed and we already end of July. Today is the anniversary day for the OpenDS project which is turning 3 this year.

As usual, this is also time to look back in the mirror and consider what we've achieved.

A little more than 10 days ago, we announced the availability of OpenDS 2.0, the new and stable release of our LDAPv3 directory server. OpenDS 2.0 came just about one year after OpenDS 1.0 and 6 months after OpenDS 1.2.
You can read about OpenDS 2.0 features in the Release Notes, but also in the various articles that have relayed our own announcement such as:

Sun OpenDS Standard Edition 2.0 CD
Yesterday, Sun publicly announced the general availability of Sun OpenDS Standard Edition 2.0, a Sun supported version of the OpenDS project, as well as the release of OpenSSO Express Build 8 (due in a couple of weeks).

Sun OpenDS Standard Edition 2.0 has the same features as OpenDS 2.0. Differences are in the branding, the license, the documentation that is available from in HTML and PDF and of course the support services offered by Sun.
Mark Craig has already posted an illustrated article describing how easy it was to install Sun OpenDS Standard Edition 2.0 on Windows XP.

OpenSSO Express builds are supported snapshots of OpenSSO development. As Pat Patterson, Community Manager for OpenSSO and covering all Identity Products at Sun, detailed on his blog, OpenSSO Express Build 8 includes a new Mobile One Time Password Feature, the Fedlet for .Net and a new task flow enabling single sign-on to

As OpenDS is getting mature, we're seeing public endorsement and use of it. In the last couple of weeks, we had 2 success stories including the use of OpenDS :

Finaly within a year, the OpenDS Community has more than doubled, in term of members in the community, but as well in the number of active contributors and participants in the #opends IRC channel, and in term of unique visitors on the Monthly visits

I'm proud of what we've accomplished in 3 years and even more of the past year. We still have a lot of ideas and customers requirements to build in the OpenDS project. Overall we know where we want to go and we hope our new executives will agree that it's a nice and viable path to follow...

OpenDS 2.0 on Mac OS X with the latest JVM...

Opends2 PictoMacOSX 10.5.7There is an issue in the start and stop scripts that is preventing OpenDS 2.0 to be installed via Java Web Start on Mac OS X 10.5 with the latest version of the JVM (Update 4 a.k.a 1.6.0_13). I've discovered the problem at the same time we were releasing OpenDS 2.0.0 release candidate 4 which was planned to be the last release candidate. So the fix is not the release but has been committed to the trunk.

The issue is that the new JVM does use a larger default minimal heap size and reject any calls with -Xmx if the maximum heap size is smaller than its internal default (around 30MB).

Still OpenDS 2.0 can be installed on Mac OS X and used with the latest JVM, by downloading the Zip file, unzipping it and doing minor edition in the start-ds and stop-ds scripts.

$ unzip ~/Desktop/
Archive: /Users/ludo/Desktop/
creating: OpenDS-2.0.0/
inflating: OpenDS-2.0.0/upgrade
$ cd OpenDS-2.0.0/bin

In the start-ds and the stop-ds scripts, replace all occurences of the string "-Xms8M -Xmx8M" with "-client"

$ cp start-ds start-ds.orig
$ sed -e "s/-Xms8M -Xmx8M/-client/g" < start-ds.orig > start-ds
$ cp stop-ds stop-ds.orig
$ sed -e "s/-Xms8M -Xmx8M/-client/g" < stop-ds.orig > stop-ds

OpenDS QuickSetup App IconYou can now run the setup program (or launch the QuickSetup application) to install and configure the OpenDS directory server.

Configuring Replication Groups: A small but important new feature of OpenDS 2.0

Opends2 Picto-2
I'm mostly done with the series of post concerning the new features of the latest release of OpenDS, the opensource LDAPv3 directory service. Yesterday, Mathieu, the developer behind Assured Replication, reminded me of a small but important new feature of OpenDS, in the area of replication: the ability to configure Replication Groups.

A replication group is a simple way to relate replicated OpenDS directory servers together. It's useful when there are more than 2 replicated servers, when the replicated servers are within different data-centers or to distinguished primary servers from secondary servers.

Replications groups are identified by a group ID which is a unique number assigned to a replication domain on a directory server and to replication servers. Group IDs determine how a directory server domain connects to an available replication server. From the list of configured replication servers, a directory server first tries to connect to a replication server that has the same group ID as that of the directory server. If no replication server with a compatible group ID is available, the directory server connects to a replication server with a different group ID.

In practice, it allows to prioritize how the replication traffic is done between the servers. In the case of multiple data-centers, it's preferable that all directory servers in a data-center are connected to replication servers in the same data-center. Only in the case of absence of a local replication server, a directory server will connect to a remote replication server.

Note that when configuring replication with OpenDS 2.0 and the
dsreplication utility, both the replication server and the directory server are configured in the same process and thus the same host. It will be very rare if the replication server is not working for its directory server.

The figure below is an illustration of 2 Replication Groups, one for each data center.

OpenDS 2.0 Replication Groups with multiple data-centers

Now to configure a replication group ?
A replication group is configured on each directory server and replication server that should be part of the same group.

On the directory server, the replication group is configured per replication domain (i.e. per replicated suffix).
First identify the replication domain

$ bin/dsconfig -D "cn=directory manager" -j /tmp/passwdfile -n -s list-replication-domains --provider-name "Multimaster Synchronization"

cn=admin data (domain 29167)
cn=schema (domain 9674)
dc=example,dc=com (domain 14741)

Then set the group ID for the domain

$ bin/dsconfig -D "cn=directory manager" -j /tmp/passwdfile -n set-replication-domain-prop --provider-name "Multimaster Synchronization" --domain-name "dc=example,dc=com (domain 14741)" --advanced --set group-id:5

For the replication server

$ bin/dsconfig -D "cn=directory manager" -j /tmp/passwdfile -n set-replication-server-prop --provider-name "Multimaster Synchronization" --advanced --set group-id:5

Repeat this to the other directory servers and replication servers that should be part of the same group.

Note that there is a group by default with the group ID 1.

Configuring replication groups have some impact when using Assured Replication, since Assured Replication only works within a single group. So groups can be used to limit the impact of network latency when using Assured Replication, or to constrain the changes to be more consistent in a single data-center.

You can find more information about replication groups in the Replication Architecture reference manual and in the Replication section of the Administration Guide.

Assured Replication: A New Feature of OpenDS 2.0

OpenDS 2.0 has just been released and there are several new and exciting features in it.

To me, the biggest innovation in this release is "Assured Replication", an extension to the loose consistency multi-master replication feature that brings tighter consistency of data between replica. "Assured Replication" is not to be taken for a full synchronous and transactional replication mechanism. A change is not transactionally applied to a set of or all replicas of a topology. With "Assured Replication", the response to an LDAP modification is delayed until the change has been received or applied by other servers, in a best effort mode. It provides a greater assurance that a change is not lost even if the server receiving it crashes.

Opends Assured Replication with Safe Data level 2

Assured Replication can function in 2 modes :

  • Safe Data Mode: an update must be propagated to a defined number of Replication Servers before returning a response to the client. So if the server or the replication server is stopped, the data is still available to all other replicas.
  • Safe Read Mode: an update must be propagated to all directory servers in the domain before the client is returned a response for the update.

Of course, for both modes, it's possible to configure a timeout interval to prevent LDAP clients to be waiting indefinitely if some servers are not available.

Configuring Assured Replication is pretty straightforward but cannot be done when setting up replication itself. So the first step is to configure Multi-Master Replication for a domain with dsreplication.

$ bin/dsreplication enable --host1 localhost --port1 5444 --bindDN1 'cn=directory manager' --bindPassword1 secret12 --replicationPort1 8989 --host2 localhost --port2 6444 --bindDN2 'cn=directory manager' --bindPassword2 secret12 --replicationPort2 8990 --adminUID admin --adminPassword secret12 --baseDN "dc=example,dc=com" -X -n

Establishing connections ..... Done.
Checking Registration information ..... Done.
Configuring Replication port on server localhost:5444 ..... Done.
Configuring Replication port on server localhost:6444 ..... Done.
Updating replication configuration for baseDN dc=example,dc=com on server localhost:5444 ..... Done.
Updating replication configuration for baseDN dc=example,dc=com on server localhost:6444 ..... Done.
Updating Registration configuration on server localhost:5444 ..... Done.
Updating Registration configuration on server localhost:6444 ..... Done.
Updating replication configuration for baseDN cn=schema on server localhost:5444 ..... Done.
Updating replication configuration for baseDN cn=schema on server localhost:6444 ..... Done.
Initializing Registration information on server localhost:6444 with the contents of server localhost:5444 ..... Done.
Initializing schema on server localhost:6444 with the contents of server localhost:5444 ..... Done.

Replication has been successfully enabled. Note that for replication to work you must initialize the contents of the base DN's that are being replicated (use dsreplication initialize to do so).

$ bin/dsreplication initialize --baseDN "dc=example,dc=com" --adminUID admin --adminPassword secret12 --hostSource localhost --portSource 5444 --hostDestination localhost --portDestination 6444 -X -n

Initializing base DN dc=example,dc=com with the contents from localhost:5444:
23 entries processed (100 % complete).
Base DN initialized successfully.

for a detailed log of this operation.

$ bin/dsreplication status -h localhost -p 5444 --adminUID admin --adminPassword secret12 -X

dc=example,dc=com - Replication Enabled
Server : Entries : M.C. (1) : A.O.M.C. (2) : Port (3) : Security (4)
localhost:5444 : 23 : 0 : N/A : 8989 : Disabled
localhost:6444 : 23 : 0 : N/A : 8990 : Disabled

Now that replication is setup, we can enable the Assured Replication mode, using the dsconfig utility. For this, on each of the OpenDS direcotry servers, we first need to retrieve the full name of the replication domain.

$ bin/dsconfig -D cn=directory\\ manager -w secret12 -n -s list-replication-domains --provider-name "Multimaster Synchronization"

cn=admin data (domain 29167)
cn=schema (domain 9674)
dc=example,dc=com (domain 14741)

$ bin/dsconfig -D cn=directory\\ manager -w secret12 -n set-replication-domain-prop --provider-name "Multimaster Synchronization" --domain-name "dc=example,dc=com (domain 14741)" --advanced --set assured-type:safe-data --set assured-sd-level:2

Note that the Replication Domain has a different value on each server, so you have to repeat these 2 commands on each instance.
Setting the assured level for Safe Data to 2 means that the server will make sure the data has been received by at least 2 replication services before returning to the LDAP client the response to the update request.

From a client point of view, there should be no difference, except that the server might take a little longer to return the response to an update request. In our measures, we found that the response time increased by 25% for Safe Data Level 2, which seems a lot, but honestly, when the response time is in the order of 2ms, it's hard to notice !

New in OpenDS 2.0: I18N Collation Matching Rules

Opends2 PictoOpenDS 2.0 has just been released and there are several new and exciting features in it.

Today we will be taking a closer look at the I18N Collation Matching Rules.

In LDAP, most of the data is made of DirectoryStrings which are UTF-8 encoded strings. LDAPv3 specifications and more precisely RFC 4518, defines the way to prepare UTF-8 strings to be compared in LDAP and OpenDS being fully compliant with LDAPv3 implements this RFC.
This means that the server will properly case-fold non-ascii characters and be able to compare properly and in a case insensitive way, none ascii characters like the French é or Japanese characters.

OpenDS Entry Editor Panel

Let's work with an example, an entry with the givenName "Hélène" illustrated on the right (click on the image for a larger view).

If I search the directory for that givenname, I can retrieve the entry:

$ bin/ldapsearch -p 2389 -b "dc=example,dc=com" '(givenname=hélène)'
dn:: Y249SMOpbMOobmUgRGVUcm9pZSxvdT1QZW9wbGUsZGM9ZXhhbXBsZSxkYz1jb20=
mail: Helene.Detroy-AT-example-DOT-com
givenName:: SMOpbMOobmU=
objectClass: person
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: top
uid: hdetroie
cn:: SMOpbMOobmUgRGVUcm9pZQ==
sn: DeTroie

$ bin/ldapsearch -p 2389 -b "dc=example,dc=com" '(givenname=HÉLNE)' givenName
dn:: Y249SMOpbMOobmUgRGVUcm9pZSxvdT1QZW9wbGUsZGM9ZXhhbXBsZSxkYz1jb20=
givenName:: SMOpbMOobmU=

Note : DN, CN and GivenName are base64 encoded in the result as expected per LDIF Specifications.
Note : To be able to type in correctly the string "hélène" in a terminal (like to the filters above), make sure the LANG is set to use UTF-8 encoded characters (LANG=en_US.UTF-8).

Let's see what happens if I'm searching for the same user without the accentuated letters.

$ bin/ldapsearch -p 2389 -b "dc=example,dc=com" '(givenname=helene)'

Nothing returned. This is because in Unicode the letter e and é do not normalize the same. Now this is a big problem, especially in Europe because we do not like when our name is not written how it should be and also because the person that searches may not remember exactly how to spell the name or may not know how to type the composed character on his machine. Also in French (but with other locales as well), the letters e and é and É are considered comparing equal.

That's where the I18N Collation Matching Rules come to the rescue.
OpenDS 2.0, like his far ancestor Sun Directory Server, supports by default a set of extensible matching rules that are locale specific.
This means I can now search for the GivenName according to the Collation Rules associated with French or German or Norvegian or Japanese.

Each locale has been assigned an OID and then there are 6 different matching rules per locale : LowerOrEqual, LowerThan, Equality,GreaterOrEqual, GreaterThan , Substring.

So if one would like to match givenname for equality according to the French collation rules, the filter would be the following:

$ bin/ldapsearch -p 2389 -b "dc=example,dc=com" '(givenname:' givenName
dn:: Y249SMOpbMOobmUgRGVUcm9pZSxvdT1QZW9wbGUsZGM9ZXhhbXBsZSxkYz1jb20=
givenName:: SMOpbMOobmU=

Or for a substring match, still according to the French collation rules:

$ bin/ldapsearch -p 2389 -b "dc=example,dc=com" '(givenname:\*)' givenName
dn:: Y249SMOpbMOobmUgRGVUcm9pZSxvdT1QZW9wbGUsZGM9ZXhhbXBsZSxkYz1jb20=
givenName:: SMOpbMOobmU=

But remembering OID for each locale and type of matching is not easy. So we've also provided some shortcuts in the form of the locale name and a short string representing the different matching; lte, lt, eq, gte, gt, sub


$ bin/ldapsearch -p 2389 -b "dc=example,dc=com" '(givenname:fr.eq:=helene)' givenName
dn:: Y249SMOpbMOobmUgRGVUcm9pZSxvdT1QZW9wbGUsZGM9ZXhhbXBsZSxkYz1jb20=
givenName:: SMOpbMOobmU=

$ bin/ldapsearch -p 2389 -b "dc=example,dc=com" '(givenname:fr.sub:=hel\*)' givenName
dn:: Y249SMOpbMOobmUgRGVUcm9pZSxvdT1QZW9wbGUsZGM9ZXhhbXBsZSxkYz1jb20=
givenName:: SMOpbMOobmU=

$ bin/ldapsearch -p 2389 -b "dc=example,dc=com" '(givenname:de.eq:=helene)' givenName
dn:: Y249SMOpbMOobmUgRGVUcm9pZSxvdT1QZW9wbGUsZGM9ZXhhbXBsZSxkYz1jb20=
givenName:: SMOpbMOobmU=

So not only those I18N Collation Matching Rules can be used in Search filters to search, but they can be used for indexing as well, and also for server side sorting.
Unfortunately, setting extensible matching rules for indexes is not possible from the ControlPanel. So it has to be done with dsconfig.

$ dsconfig set-local-db-index-prop \\
--backend-name userRoot \\
--index-name givenName \\
--add index-extensible-matching-rule:fr.eq \\
--hostname ludovic-poitous-computer-2.local \\
--port 5444 \\
--trustStorePath /Users/ludo/dev/Tests/OpenDS2rc4/config/admin-truststore \\
--bindDN cn=Directory\\ Manager \\
--bindPassword \*\*\*\*\*\* \\

Don't forget to rebuild the index for the givenName attribute (bin/rebuild-index -b dc=example,dc=com -i givenname).

You can find more information about the I18N Collation Matching Rules on the OpenDS 2.0 Documentation Wiki.

New in OpenDS 2.0: Monitoring in the Control Panel

Opends2 PictoOpenDS 2.0 has just been released and there are several new and exciting features in it.

Today we will look at the new feature in the Control Panel: the monitoring aspect.

At first look when we compare the Control Panel for OpenDS 1.2 (on the left below) and the one for OpenDS 2.0 (on the right below), not much has changed. Except for the left bar menu that contains a new section: Monitoring and a status bar at the bottom of the panel.

OpenDS 1.2 Control PanelOpenDS 2.0 Control Panel

Let's look a little more in details what kind of monitoring information for the OpenDS server is now available:

General Information.

OpenDS 2.0 General Monitoring PanelIn the General Information Panel, you will find overall statistics such Connections, Up Time, but also information related to the system like the name, OS, number of CPUs, available memory in the JVM. You will also have a screen dedicated to the Java VM specific information (see below) such as the version, the vendor, the running arguments, a lot of details about the various segments of memory of the VM. A third screen highlights the work load. The fourth one gives details about the entry cache and the fifth one gives details about the local backend database environment, i.e. low level statistics on memory, transactions, locks in the database. There are more than 50 parameters from the database that you can retrieve and look at with the "Show Operations..." button.

OpenDS 2.0 Monitoring Java VM

The Connection Handler.
The Monitoring Panel for the Connection Handler gives greater details about the LDAP operations that are processed by the server, sorted by kind of Connection: what goes on the LDAP port, what happens on the LDAPS port and the Administrative operations.

OpenDS Connection Monitoring

There are many more statistics information available from the OpenDS server, either through LDAP, JMX or SNMP if you have enabled the later two. Not everything can be displayed in the GUI, and in future version we will provide external tools or widget to graph some of the monitoring information. Meanwhile, play with the Monitoring screens of the OpenDS 2.0 Control Panel, and let us know what you think, what you like, what you feel is missing.

And for a supported version of OpenDS, please check Sun OpenDS Standard Edition 2.0
